I forgot the report. Here we go.

----------------------------------------------------------------------
1. OpenPrinting Database
------------------------
http://www.openprinting.org/
http://openprinting.org/driver_list.cgi
http://openprinting.org/printer_list.cgi
http://www.linux-foundation.org/en/OpenPrinting/Database/DriverPackages
- Database of all printers for which is known whether they work or do
not work under Linux. Information collected by users and printer
manufacturers. Includes information about which drivers work, which ones
are recommended, which ones deprecated, ... Users can directly
contribute comments and new printer entries.
- Database generates PPD files for many free software drivers,
especially the built-in drivers of Ghostscript.
- Database hosts ready-made PPD files from printer manufacturers, mostly
for PostScript printers, but also for PCL printers using Ghostscript
drivers.
- Database hosts also LSB-based RPM and Debian packages of drivers.
These packages can get installed on all LSB-compliant Linux
distributions. This simplifies driver installation for users (no
compiling, one package for all distros) and driver packaging for driver
developers and printer manufacturers (One LSB RPM for all distros, less
packaging and testing work and cost). The package repositories are
indexed for automatic updates with the distro's package managers (apt,
yum, ...).
- Web query API for automatic look-up of driver packages and PPDs. This
allows printer setup tools and (like system-config-printer) and driver
managers (like Jockey) to automatically find suitable drivers for an
auto-detected printer, and to download and install them automatically.
http://www.linuxfoundation.org/en/OpenPrinting/Database/Query
- Foomatic software for use of local copies of the database and
integration of all printer drivers with the printing systems. This is a
core part of the printing infrastructure in all distributions.
- I am working together with the printer manufacturers to help them
packaging the drivers and with developers of configuration tools
(system-config-printer by Tim Waugh, used by default in Fedora/Red Hat,
Ubuntu, an Mandriva; Jockey by Martin Pitt, working for the LF's Driver
Backports group),
- 1 GSoC 2008 student has worked on a web application for administration
of user contributions and uploads and he is still working on it. He will
work on it full time in his project semester Dec 2008 - May 2009.
- I am also taking care of keeping the system running and adapting it to
the increasing traffic.
2. Common Printing Dialog
-------------------------
http://www.linuxfoundation.org/en/OpenPrinting/CommonPrintingDialog
- I have organized the development of a Common Printing Dialog for all
applications and desktops to make printing easier by having only one
dialog with access to all functionality without being overloaded.
- The design was done by OpenUsability people who met regularly on the
Printing Summits organized be me and on an additional meeting (2006-2008).
http://wiki.openusability.org/printing/index.php/Specification
- The implementation is mostly done by two GSoC 2008 students: Dialogs
for KDE and GNOME and a D-Bus API to call the dialogs out of
applications. Patches for Qt/KDE and GTK/GNOME libraries to make most
applications using the new dialogs are planned. Big part of the
mentoring of the students was done by me.
http://www.linuxfoundation.org/en/OpenPrinting/PPDExtensions
http://www.linuxfoundation.org/en/OpenPrinting/CommonPrintingDialog/TestDialogFromBZR
- During the implementation work period of the GSoC 2008 students I have
designed specs for PPD extensions so that driver developers/printer
manufacturers can make use of the dialog's functionality to present
their driver's user-settable options.
http://www.linuxfoundation.org/en/OpenPrinting/PPDExtensions
3. PDF as standard print job format
-----------------------------------
http://www.linuxfoundation.org/en/OpenPrinting/PDF_as_Standard_Print_Job_Format
I have coordinated the replacement of PostScript by PDF as the standard
print job format and created a reference implementation in the upcoming
Ubuntu 8.10 (Intrepid) distribution. Bug reports in the Ubuntu bug
tracking system stabilized and matured the new filters.
Several CUPS filters for handling PDF were implemented by OpenPrinting
Japan. I have evaluated and tested them and checked their ability to be
packageable for Linux distribution. I told the people of OP Japan what
needed to get changed and where there are bugs and they fixed it.
Other CUPS filters where done by a Google Summer of Code student. I have
done part of the mentoring here.
foomatic-rip was made capable to take PDF input by a student who worked
on an internship at the Linux Foundation. He worked under my supervision.
I have also reported several bugs and feature requests to Ghostscript,
CUPS, OpenOffice, ... to make the PDF workflow work and to move it
forward. I have also fixed several bugs in Ghostscript and the filters
by myself.
4. Printing Summits and other meetings
--------------------------------------
http://www.linuxfoundation.org/en/OpenPrinting/MeetingInfo
Organization of yearly Printing Summits (on the Linux Foundation
Collaboration Summit from 2009 on) where all important people having to
do with printing under Linux will meet: Printer manufacturers, Linux
distribution developers, desktop, application, driver, core printing
system developers. Here the future development is planned and important
decisions are made.
Organization of additional meetings if needed, for example meetings with
the Japanese OpenPrinting workgroup and printer manufacturers in Tokyo
(Nov 2007, July 2008).
5. Coordination/Integration of printing-related free software projects
----------------------------------------------------------------------
General: Reporting bugs to CUPS, Ghostscript, and driver projects, also
fixing smaller bugs. Participation in development discussion.
Cooordination between the projects. Bug and incompatibility workarounds
via Foomatic.
Ghostscript: Merge of ESP Ghostscript with GPL Ghostscript so that
distros can use the newest GPL Ghostscript with all drivers (beginning
of 2007).
In 2008 several bug fixes, like Duplex, Resolution, and InputSlot for
PCL-XL drivers (pxlmono/pxlcolor), discussion with GS developers about
further development, driver integration, PDF capabilities, ...
CUPS: Bug reports feature requests, development discussion, also some
bug fixes.
HPLIP: Testing on real printers (supplied by HP through USD 10000 PO
July 2007-June 2008, new USD 10000 PO 2008/2009 in place), bug fixes,
development discussion.
6. Development and creation of printing APIs for Linux/Unix
-----------------------------------------------------------
http://www.linuxfoundation.org/en/OpenPrinting/PAPI
http://www.linuxfoundation.org/en/OpenPrinting/JTAPI
http://www.linuxfoundation.org/en/OpenPrinting/APAC
Printing API (PAPI), Job Ticket API (JTAPI), Printer Driver API (PDAPI,
OpenPrinting Vector), ...
1 Google Summer of Code 2008 student has done the CUPS implementation of
PAPI.
7. Organization of the GSoC 2008 participation of the Linux Foundation
----------------------------------------------------------------------
http://www.linuxfoundation.org/en/OpenPrinting
http://code.google.com/soc/
http://code.google.com/soc/2008/linux/about.html
http://www.linuxfoundation.org/en/Google_Summer_of_Code
Application for the Linux Foundation as mentoring organization, setup of
project ideas, evaluation of student applications and assigning them to
projects and mentors, reminding mentors and students to deadlines,
mentoring work on the Common Printing Dialog, the OpenPrinting Database
Admin web app, the PDF filters, ...
8. OpenPrinting Steering Committee
----------------------------------
Monthly phone meetings to plan the actions of OpenPrinting, report about
what got done, organize meetings, ...
9. Printing Requirements in the LSB
-----------------------------------
I have made important printing-related requirements going into the LSB,
which is very important to make distribution-independent printer driver
packages possible.
http://www.linuxfoundation.org/en/Specifications
http://refspecs.linux-foundation.org/LSB_3.2.0/LSB-Printing/LSB-Printing/book1.html
Future plans
------------
In addition to the continuation on the topics mentioned above, we plan
to do the follwing:
1. Printer (hardware) testing and self-verification program with branding
We need to create a procedure for that, so that hardware vendors can
tell potential customers that there devices work with Linux
2. Integrating color management as standard part into the printing
workflow. In Mac OS X this is already standard. In Linux this is really
missing. The PDF printing workflow is already the first step towards it.
3. Having more eyes on desktops and applications, about which printing
dialogs they use the quality of their PostScript or PDF output, whether
they switched already to PDF, ...., rgreesions,...
4. Organize the next OpenPrinting Summit as part of the Linux Foundation
Collaboration Summit in April (?) 2009.

I'm around, well, sort of. I am still involved in printing and have
many things that I would like to get done, but I also have another role
at Sun that is eating up a very large chunk of my time. I should be on
in an hour.

Hi,
InstantConference has an easy recording facility for phone meetings. If
activated, one gets a download link for an MP3 file with the recording.
I have transferred the file for the last OP Steering Committee meeting
to the OpenPrinting server:
http://www.openprinting.org/download/meetingnotes/op-steering-committee/OP-SC-Meeting-20081201.mp3
In general, recorded meetings I will upload to
http://www.openprinting.org/download/meetingnotes/
This SC Meeting was small. Only George Liu, Norm Jacobs, and me
participated. Also not very important stuff was discussed. I reported
some stuff of my activity, and Norm told about the development of the
printing part of Solaris. They take more and more of the Linux printing
stack: CUPS (should get standard with CUPS 1.4), system-config-printer
(printer setup tool), hal-cups-utils (Plug'n'Print script), ...
Foomatic, Ghostscript, HPIJS, and Gutenprint they used already. Norm
showed also interest in printer driver download from OpenPrinting for
Solaris.
I asked Norm also to tell about how successful he was with the work of
his GSoC student to implement PAPI for CUPS. Norm told that they were
not so successful and he also did not have enough time for the
mentoring. We also concluded that PAPI will most probably not adopted,
as we end up with CUPS everywhere. So we should better work more on
existing de-facto standards than creating new things with the intention
that they should get a standard in the future.

P. S.: The MP3 is 23 MB long, 73 minutes of talking.

Yes I can do that. I was not too sure where I should send it so I kept it
private.

Color Management types would say "color space transform" rather than "color
correction" because this could also be doing things like taking an RGB (or XYZ
or Lab) document and converting it into CMYK or even deviceN output for the
printer.

Doing the transform on the server would be the preferred way to handle this.
Right now we are limited to doing this client side in the user land apps that
are sending output to the print server. This means we only have color managed
printing in those apps that know how to do color managed printing which right
now is a very limited set of apps (probably less then a dozen total but I can
only think of three off hand and one of those is a specialized front end for
gutenprint). Having this functionality on the server side means that even CM
dumb apps benefit once things are properly configured.

I think this assessment is correct. In fact having this happen in the
*toraster rendering filter makes things much simpler for everyone since doing
this would eliminate the need to do any color management specific
modifications to the individual drivers and it would also centralize this
functionality in one place. For example once GhostScript has been updated to
have an up to date CM implementation (I think we should have at least
development versions with this capability soon) and the new pdftoraster filter
is setup to handle CM the new pdf based printing work flow will have
functional CM for all apps using it, including apps that are not CM aware, no
matter what printer/driver is being used.
As a side note Poppler has now been patched with preliminary CM functionality
and the testing I did with it seemed to work OK. So it might make sense to
continue to use Poppler for the common printing dialog since it's CM support
might be "good enough" for this use.

Currently the CUPS API allows client side apps to get a list of profiles that
are in cupsICCProfile lines in the PPD. But there were several open issues
with the CUPS implementation the last time I checked.
1. If the CUPS server is not local there is no way to get the profile for soft
proofing.
2. CUPS only allows passing a user specified printer profile on the command
line if the profile is installed in a specific directory on the CUPS server
and there is no way in the general case for a client app to get a list of
these profiles or to get a copy of any of these profiles.

That is why I registered. I live with in commuting distance of the conference
which makes it fairly easy for me to attend. So I guess that I will be the
OpenICC representative there and perhaps there will be others as well.

ICC profile location/directory structure was talked about at the meeting.
OpenICC recommends basing the location of ICC profiles on the XDG Base
Directory Specification. This is what is currently implemented in Oyranos.
The current OpenICC specification for this can be found here:
http://www.oyranos.org/wiki/index.php?title=OpenIccDirectoryProposal
also see:
http://bugs.freestandards.org/show_bug.cgi?id=77
This specification was initially promulgated in 2005 and has been through a
number of revisions since then and is subject to additional changes going
forward. It should be possible to extend this to include printer specific
requirements if this is needed. For example one system wide location from
this specification is
/usr/share/color
and all profiles there must be located in
/usr/share/color/icc
But the specification allows for things like:
/usr/share/color/icc/printer
and it is possible to do something like:
/usr/share/color/icc/printer/Epson
For printer profiles for Epson printers.
or
/usr/share/color/icc/printer/Epson/R2400
or
/usr/share/color/icc/printer/GutenPrint-5.2/Epson_R2400
or even
/usr/share/color/icc/printer/GutenPrint-5.2/Epson/R2400
But presently no one is using anything beyond:
/usr/share/color/icc
That is everyone is currently using a fairly flat directory structure since
most systems have a very limited number of profiles (at most a few dozen) and
there does not appear to be any reason to go farther. However on a system
that is used as a print server with a large number of connected printers with
dozens or hundreds of printer profiles an extended directory structure may
make sense. The specification allows for this but does not require it nor
does it contain any details for what this extended directory structure would
look like beyond the base <prefix>/share/color/icc/printer directory.
It might make sense to look at this in connection with the GSoC OpenICC
Oyranos printer project. This is also probably something that should be
settled before CM is added to the pdf2raster CUPS filter so that CUPS can be
updated to handle this correctly.

I am working on the UI design of the CPD and looking at the controls
and parameters for colour, both as presets/profiles and as more
detailed controls. Therefore, I'll need to get a good understanding of
how this all works.
Including:
the workflow from application to printer
colour profiles
color management; in applications, and printer colour management.
what happens where?
detailed user interaction: what controls need to be there?
Can someone point me in the right direction? Provide some useful
information or sources of information?
Thanks in anticipation,
Kate

I might be able to help at least with respect to color management. This is a
complex area with lots of unresolved issues. Here is some high level info
about the current state of things.
Applications:
Currently there are two general types of applications with respect to color
managed printing.
1. Printing color management dumb applications. This is the most common type
of application. These applications either are completely color management
dumb (IE. don't know anything about color management and do not use it
anywhere) or are lacking color management in the printing work flow. GIMP is
an example of an app that knows about color management but has no CM support
in the printing work flow.
2. Apps that are fully color management aware. This includes apps like
PhotoPrint, CinePaint and Scribus. These applications allow users to
transform the document to the printers color space before it is spooled to the
printing back end.
CUPS:
Currently CUPS is architected to allow for color management in the server IF
the *toraster filter being used supports color management. At present none of
the open source filters do (unless recent versions of the pdftoraster filter
have this support now - what is the status of this?).
CUPS server side CM is setup in the PPD file for the printer in the
*cupsICCProfile settings. Currently in the PPD files that come with GutenPrint
these settings are completely wrong and point to profiles that do not exist in
directories that do not exist on most *nix machines (these appear to be OS/X
specific IE. "/System/Library/ColorSync/Profiles/sRGB Profile.icc"). In
addition when I change these and later install a newer version of the driver
these settings get stomped on (not good - we should be able to do better).
Only admins can change the CUPS settings for the profiles that will be used by
the server and this can only be done by editing the PPD file. The only
application that I am aware of that will display a list of these profiles for
end users is Kolor Manager which is in the playground area of KDE SVN. The
current CUPS web admin app does not display these nor does it have facilities
for making changes to these settings.
CUPS will only use profiles (logically) installed in the correct location on
the server. Typically /usr/share/cups/profiles on linux machines. This
location is not compliant with other standards (XDG & OpenICC) regarding where
files like this should be located.
For more detail see the CUPS PPD documentation.
In an ideal world:
1. CUPS would have *toraster filters that are CM aware (I think this work is
underway at least with the pdftoraster filter).
2. Server side CM settings for printers would be persistent across upgrades.
3. The CUPS web admin app would display these settings and allow users with
the correct privileges to make changes to them.
4. Default printer CM settings in the PPD files would be nominally correct for
each platform.
5. Applications that are CM dumb would have color management handled in a
transparent way by CUPS. This should be the case once #1 and #4 are
corrected.
6. Applications that are CM aware would be able to disable CUPS server side CM
and handle CM locally. This is also needed for printing color management
targets for creating custom profiles.
7. The CPD has the potential to make all applications printer CM aware.
8. CPD would integrate with system level CM configuration tools like Kolor
Manager/Oyranos.
The above is mostly high level and may not have been particularly useful.
There is a lot of complexity and many unresolved issues that may make it
difficult to implement CM in the CPD at this time. For example the server side
CUPS CM facilities are currently not working so that means that the best we
can hope for at this time is for the CPD to somehow handle doing this before
spooling the print job. Later when the CUPS server side CM becomes functional
changes will need to be made in the CPD to allow users to select either server
side or local CM.
Does the CPD still use poppler for pdf rendering? If so recent versions of
poppler now support CM although this support is limited (you can't set
rendering intents for example). If that is the case then it might be possible
to leverage poppler to make user space printer CM possible. If you have
switched to GhostScript then you will need to wait for them to complete their
CM work that they have underway.
You might also consider asking on the OpenICC email list since I am sure that
you will get lots of feedback there about how this should work. Many of
those that work on printer stuff are also members of the OpenICC list (Till and
Robert Krawitz for example). In addition the developers of Oyranos and Kolor
Manager are members along with most of the other CM people who are doing open
source work.

The following text will merely describe what I would like to see as a
user. Some comments are added to explain what is meant colour management
wise. Please do not wonder when not even print device selection is
mentioned in my text. I assume such all to be covered elsewhere.
As Scribus and other projects have focus and a long experience with
printing, it would shureley be great to read their thoughts or comments,
what they would think are useful CM options for CPD.
Starting the print button I would like to see in a colour management tab,
offering following basic controls:
Colourmanage by System (*)
Colourmanage in Application ( )
No Colourmanagement ( )
The first would be part of the CUPS *toraster system once its
implemented.
Colourmanage in Application (early colour binding):
A print device profile is needed. So with this option enabled a
selection for a "Separation profile" should appear showing the
system installed profiles. The one ICC profile matching the actual print
conditions the most should be preselected. The other matching and non
matching profiles should follow in a descending order in the selection
list. Once Oyranos is distribution ready and availabel it can help in
preselection and device to profile association.
The set of useful profiles is dependent to the print process. E.g. for a
"Rgb" printer I would not like to select a Cmyk or nColour profile, for
"Cmyk" not a Rgb one.
For application colour management the responsibility to match between
options and ICC profile lays in the hand of the user with the help of a
hopefully well designed application and its helpers.
It is important to note that any print profile is useful only
within a defined set of variables associated with print device, medium,
ink set, driver and driver settings. The Oyranos CUPS module tries to
cover these relations as they are programatically reachable.
Two ways to get profile to print condition matching UI wise I may outline.
preserve - would mean the user selects a print queue.
Then a profile selection system can detect a list of
available and useful profile and they are presented to the
user. All colour related options, except the above and below
mentioned colour management options are not changeable. So e.g.
a user can change positioning but not the ink set. This is a
typical colour managed mode as many vendor drivers offer.
A UI, offering expert level control, may allow to prominently
breaking the profile to print settings relation as a special
option. Typical a warning dialog could popup to say "Hey, do'nt
change this setting or your profile does not match any more.
Cancel[x] Break[]". You may have an alternative to popups.
sync - a user can select whatever options are permitted by the other
UI components. The ICC device profile selection is updated
instantly (assuming its fast enough).
The rendering intent, blackpoint compensation would be needed as the
minimum of options. Additionally a "Simulation profile" and further
options of the selected CMM can be helpful to designers and prepress
people. E.g. "Preserve Black" and the like for Cmyk2Cmyk conversions.
After that I would expect the document gets flattened and converted to the
requested device colour space, which in turn is sent unaltered to the
printer. The selected separation profile (must) be embedded and the whole
thing marked as further not to be colourmanaged.
Some PDF variants allow for that. But I am no PDF expert. So someone with
certain knowledge in this field could hopefully tell more precisely, which
exact PDF versions and attributes are needed to do this in a standard way.
Colourmanage by System (late colour binding):
Here is not much to say. The document needs all colour spaces be assigned
properly, that a remote print host can make colourful sense of the
content. A option for "Flatten Document Colour Spaces" would help in
disambiguating the compositing colour space. That is useful for mixed
colour space documents only. The resulting colour space of a
colour space flattened document would be the compositing colour space,
which is typical the default editing Rgb colour space, but can differ in
some situations. The responsibility to correctly render the document is by
the print system. Such documents are most portable, as they do not need a
retargetting, and should therefore be the default setting.
This approach is in colour terminology called late colour binding, because
the colours get their final values in a rather later stage.
No Colourmanagement:
Omit all colour management related settings and enshure that the content
is not altered during the spooling and printing. This option is important
to print colour target, prematched files and for special applications,
where altering of the content is undesireable. It preserves the state as
is now.
A print preview with a check box to "Simulate on Monitor" would be great
and many consider it a basic feature, as it will help users to predict the
print results. To do the proofing, the selected print profile would work
as the simulation or proofing profile. The target is the actual monitor
profile for that screen region. Oyranos has code in the CUPS module to
obtain certainly the locally stored user accessible ICC device profile.
Any CUPS profiles, being them local or remote, need more details worked
out to fit in seamless in a easy manageable workflow.
If you want to make a professional feature available the kind of on screen
simulation can be selectable. This means to be able to alter the rendering
intent for the proofing profile which is separate from the document to
print rendering intent. The rendering intent for the proofing profile can
be eigther relative colourimetric as a default and optional absolute
colorimetric. The later would allow for a "Match to Light Booth",
compensating for white point differences and do no compensation for the
monitor white point. A further option would be to "Simulate Paper White"
on screen, which is included in the previous option as well but without
the absolute white point.
Vendor ICC colour profile can be included by device dedicated PPDs and
therein configured ICC profiles.
A "Save to PDF" button with all settings applied would be welcome, but is
shurely already covered by the requirement.
kind regards

I am not sure that "Colourmanage in Application" is a good descriptive term
for this option although "early binding" is somewhat descriptive. What is
being described is color management on the user machine (in user land) in the
CPD (or perhaps a CPD color management add in of some sort). The distinction
is that some applications do their own CM (Scribus, CinePaint PhotoPrint...)
and the print system has no way of knowing about this. Doing color management
in these apps the user would select the No Color Management option and calling
this option color management in application could be confusing.

This should be the default once CUPS has CM aware *toraster filters (or at
least a CM aware path). Like the early binding setting it should have a way
for users to select rendering intents, black point compensation and possibly
preserve black. Also these setting need to be passed to and used by the back
end.

That is all color values are assumed to be device values and should not be
altered.

Even without proofing the CPD should use any installed (IE. X11 _ICC_PROFILE
atoms) profiles to color manage what is displayed on the screen. This is a
good starting point and adding proofing later will be much easier.

Currently the CPD only allows for a fairly small preview. This limits it's
usefulness for soft proofing. Most users interested in having on screen soft
proofs will be using applications that have the ability to do soft proofing and
that allow these proofs to be displayed in a larger window. GIMP, Scribus
and I think CinePaint all support soft proofing.

Too many users try to tweak every knob we have, and too many drivers provide extra knobs that interfere with managed color reproduction. The best advice we can give to our users is to turn off all of the vendor controls (if necessary) and leave our color controls set to the defaults. If Linux wants to avoid the "mistakes" of the Mac and Windows world, eliminate vendor controls and minimize (or eliminate) the "standard" color controls. Let the "expert" applications provide controls for color profile and rendering intent, which is equally important to make out-of-gamut colors look reasonable, and leave those controls out of the standard/general print dialog.
I agree with most of this. Although I don't know if printer manufacturers would agree to relinquish their own color controls. I'm not a huge fan of their controls and I think they are a waste of space. But they do likely achieve a major goal for manufacturers, which is platform parity for their products.
> From the point of view of a color-managed workflow, the ideal color space for printer drivers is DeviceN, i.e. a 6-color printer gets 6 color channels, with the separation defined by the ICC profile for that printer, media, color mode, etc. However, the reality is that we don't have tools to create or the infrastructure (at least on Mac OS X) to handle profiles with more than 4 channels, and thus most drivers take RGB or CMYK and map it to DeviceN as needed. Because of this, custom printer profiles are of limited usefulness in a printing workflow - you can (and many people do) tweak the output for a particular set of printer, inks, and media, but the results are not ideal because you are not manipulating the color in the printer's native color space. Moreover, many high-end printers now provide so-called "closed loop" profiling on the printer to normalize the output for the current supplies and environment, making the "traditional" manual profiling workflow unnecessary.
I don't agree with most of this.
The quality of the RGB->DeviceN "black box" provided by a manufacturer for an e.g. 6-color printer, is what determines how effective profiling it can be. For example the Epson Stylus Photo 2200 had a really piss poor Off (No Color Adjustment) LUT. It was wider gamut than the Photo Realistic or Vivid LUTs, but it had nasty gray balance and seriously clipped detail in shadows. It was worth profiling over despite this, for certain classes of imagery. Other classes, it was best to profile over the Photo Realistic mode.
Newer printers, Epson Stylus Pro 3800 or 3880, for example, the Off (No Color Adjustment) LUT is quite well behaved, even compared to the sRGB or Adobe RGB LUTs offered by the driver. Professional, fine-art photographers have been building custom RGB ICC output device profiles over these LUTs for such professional printers for years, using the manufacturer supplied driver, and have achieved superior results compared to either the sRGB or Adobe RGB LUTs.
There are a couple of products on the market that can build 5+ channel ICC output device profiles. They are old, and expensive, and it's unclear exactly how well they work compared to an RGB ICC output device profile over a good (or decent) RGB->deviceN black box LUT provided by the manufacturer. What is clear is that it's non-trivial making such deviceN ICC output device profiles even if you have the software to build them, or an OS that could support them. The profile target you use is a challenge to figure out how you're even going to print it correctly. And then you have a healthy amount of testing to manually determine what the ink limit should be, since ink limiting is the responsibility of the profile, in this paradigm, if there is no black box in the middle of the process. And channel cross over behavior, ink limiting and GCR is really non-trivial.
Looking and high-end proofing products, even that is rarely done with DeviceN ICC profiles for inkjet proofers. If it's an Epson inkjet, most products on the market today depend on Epson's HTM (halftoning module), which is the guts of their black box which can accept either RGB or CMYK input. So the inkjet is still profiled as either an RGB or CMYK device, and the HTM is responsible for further separating that out to deviceN. (For dot proofing on inkjet, other considerations are needed.)
So I disagree that "custom printer profiles are of limited usefulness" or that the "results are not ideal." I have much bigger complaints than not being able to peak inside the Epson/Canon/HP black box. I'm annoyed that it's so f'n difficult to reliably print profile targets on Mac OS X without ColorSync sticking its nose into the wrong business. When that happens, the resulting profile is completely FUBARd and that is truly of limited usefulness and results that are not ideal.

Well they don't. None of them do this correctly. All try to submit a target and then the driver defaults to vendor color matching, typically expecting sRGB as the source space. The user must manually set a "no color management" color setting, because none of the profiling tools use the APIs to inform the OS which then informs the driver to change to the proper mode for building an ICC profile. If we get the driver configured correctly, then yes we get a valid profile target, without ColorSync involving itself.
However, none of the high end profiling tools print targets directly through the OS. Those targets are TIFF, and need to be printed from an application that can correctly print and not color manage the target, and then also inform the OS (the pdftoraster filter, and also ColorSync) to not convert the target. Presently on Mac OS the application of choice is Photoshop, with which we are presently having problems because the No Color Management based PDF spool file has different profiles set for the profile target object, and OutputIntent, causing ColorSync to color manage. It autoconfigures newer print driver settings correctly, but the PDF spool file is malformed, so we get a converted profile target.
I have looked quite long and hard on Apple's developer web site for documentation explaining the architecture and how to avoid transforms and was not successful. The API to get the print driver to set itself to the proper mode for use with an ICC profile using application color matching isn't locatable either.

We can certainly blame such problems on drivers, and be correct.
Yet an off mode for ColorSync doesn't exist. It depends on null transforms. That's the bigger flaw, in my view, because achieving null transforms is complicated. An off switch is much easier, and thus more reliable.
An explicit off switch is allowed in PDF/X-3, while still implicitly tagging the data. DeviceRGB being persona non grata, by Apple, in the PDF spool file is a big source, in my opinion, of the problems we've been having on Mac OS. DeviceRGB could have (and should have) acted as a fail safe for calibration/characterization/prematching workflows. While a small percent of the market, these workflows are the #2 workflow behind simply leaving the driver set to defaults.
> A very common problem with the Epson drivers is that the Epson color controls are not actually disabled in ColorSync mode! However, bugs like those are propagated to avoid "breaking" existing users' workflows (!?!)
I have two current drivers for two different Epson printers and neither of them behave the way you're describing. When I set ColorSync mode, the Color Settings pop-up menu changes to "Off (No Color Adjustment)" and all of its color controls found in Advanced Color Settings vanish. Instead, they are replaced by text explaining the profile that will be used when printing. It appears to be the correct behavior. I know older drivers, for way too long, did behave the way you describe. And yes that's all on Epson, but the documentation is weak, and documentation search on the dev site simply sucks.
So, presently we're unable to reliably print profile targets from Photoshop, using No Color Management (in Photoshop) and Off (No Color Adjustement) in a wide assortment of newer Epson drivers. What happens is, I get a completely borked profile target in printed form. Inspection of the PDF spool file indicates source≠destination, and thus ColorSync is going to come riding in to convert the job.
DeviceRGB being set as the color space would avoid this. Content that is calibration/characterization/prematch from an application, has no business being ICCBased in the PDF spool file.

On most *nix (non-OS/X) systems where users are trying to do color critical
work the users will be using the GutenPrint drivers if there is a GutenPrint
driver for their printer(s). Not those from the device vendor. In many
cases the device vendor does not even have a *nix driver for the device.
When using the GutenPrint driver the user is interacting directly or nearly
directly with the driver and has a degree of control that is far beyond what
OS/X or Windows users have over these devices. That interaction is generally
controlled by the printer driver PPD file. This includes the ability to do
RGB, CMYK and DeviceN (if the printer has more than 4 channels) printing as
well as to change things like ink limits, GCR, sub-channel transitions and
LUTS. The UI for doing some of these things is a little on the primitive side
however.
In addition work is underway on a tool that will create calibration
(linearization) curves for GutenPrint driven printers using various
measurement instruments (actually using ArgyllCMS to do the measurements).
This tool is called GPLin and is still an alpha level tool but it is getting
closer to being a useful tool as it goes through regular updates by it's
author (Alastair M. Robinson).
But to Chris' main point. For RGB and CMYK printing paths there is indeed a
black box built into the driver that is doing some "color management" but with
our open source drivers we also have true DeviceN available. I have done
extensive measurements of the response curves of my GutenPrint driven Epson
R2400 printer and for the most part it's CMYK channels have fairly smooth
response curves with minimal anomalies in the dark to light ink transitions
although the magenta channel could be improved in this regard. In other words
the GutenPrint driver presents this printer as fairly well behaved CMYK device
and CMYK profiles I have created for it using ArgyllCMS give very good results.
I suspect that the same thing is true for those who are using this
driver/printer combination but are using it's RGB mode and it is likely true
for most of the Epson printers supported by the GutenPrint drivers.

And this is critical for those folks who are doing color critical work. If we
don't have a straight forward way to print profiling/calibration targets then
there is a problem.
Robert Krawitz quotes Eric Crampton in the footer of all of his emails thusly.
"Linux doesn't dictate how I work, I dictate how Linux works."
I think it is fitting to use that quote to help make the point that many Linux
users expect to be in total control of their machines. Anything that reduces
their control will at best be viewed with suspicion. For example I have been
running patched and hand modified kernels for a long time and I have other
software on my system that I have modified so that it works the way I want. No
Windows or OS/X user would even think about running a customized kernel yet it
is fairly common for Linux users.
On the other hand since we are dealing with open source code the problems
listed below should not happen. For example if the drivers don't work the way
they should and if the vendor will not fix the issues then we can fork the code
and get things fixed. We are NOT dependent on hardware vendors to get things
fixed.

I think the same things should be true for DeviceCMYK since this is simply a

The problem of course is that in the larger world many PDF documents use
DeviceRGB as a way of doing untagged RGB. In fact I don't think the PDF
specification allows for untagged objects so the only option people have for
creating PDF documents where they don't have to tag the objects in very
specific ways is to use DeviceRGB. Apple appears to be trying to "fix" this
problem and their fix has the unintended consequence that it makes
calibration/characterization/prematching very difficult. My gut tells me that
they are trying to fix this problem in the wrong place and this is why we are
having these issues.

This whole area is very difficult because of it's complexity. There was lots of
work this summer on Oyranos in this area and I think it is worth while to
follow up on that work to see if we can't iron out any remaining issues so
that a linux (or other FOSS OS)/Oyranos/CUPS/... system really works the way
it should. But lets be clear that this will not be easy to solve.

This is back to the RGB only assumption of Windows and OS/X. Many of our open
source printer drivers support RGB as well as CMYK and true DeviceN. Since we
have more flexible drivers available I think it changes how we should approach
this problem to some extent.

I understand, vendors regularly get things wrong.

Basically this hasn't been included in public documentation because even the "experts" writing profiling software have used the API incorrectly (for various reasons the API is semi-complicated), and we don't want to encourage the use of device color on Mac OS X except when it is actually needed (which is basically only when printing a target or doing application color management...)

Sure. Any scenario involving calibration, characterization, or application prematching, requires it. That would be a few scenarios. But they are rather mission critical scenarios for those who depend on it.
It doesn't seem like making ColorSync so hard to turn off has really achieved anything, but lots of problems over the past 5 or so years, for professionals who depend on printing, especially to inkjet printers.

That was an opt in system of color management. The default was DeviceRGB. I am not proposing that model. I'm proposing simplifying the opt out mechanism, and making it robust. Right now it's the year 2009 and this is as bad and inconsistent as it has ever been.

Well if Apple didn't operate like the KGB, as though everything is such a huge fricking secret, and clearly and thoroughly documented how things are supposed to work, it would at least make it easier to identify what is incorrect behavior, and whose bugs these are.

Michael, yes, I have no doubt about that. The problem is that these sorts of color problems with printing are recurring themes. Epson is not the only one who has had problems, although they very well may be the worst offender. But we don't have these kinds of problems on Windows. That should be a WTF moment for Apple. Sane people have started to wonder, rationally, if there is something wrong with the architecture when there are so many recurring problems of this sort, through multiple major revisions of the operating system. We've experienced color related problems with Tioga drivers too.
> DeviceRGB (like what we went through in 10.4 and earlier) only led to more problems since all output was uncalibrated.
There is a very rational, workable medium between totally uncalibrated, which is not what I'm advocating, and forcing everything to be ICCBased. It is fundamentally inappropriate for calibration/characterization/prematch data to be ICCBased. That is a serious systemic problem, and a cause for many of the problems we've been having.
DeviceRGB + an OutputIntent is not the same thing as what you had with 10.3 and earlier. It is not uncalibrated. And I'm not suggesting most applications would have such PDF spool files. Just the ones that explicitly call a particular "calibration API".
Presently, it is possible for PDF spool files to appear with an OutputIntent of None, which I find equally baffling to the lack of DeviceRGB. In my view the PDF spool file is formed exactly backwards. OutputIntent should be required, as it is in all PDF/X. That is the implicit source for device data, enabling the soft proofing of even application prematched data - or even retargeting to a different output device, if necessary.

I have to disagree here. I have three different "grades" of glossy
photo paper here, from different manufacturers. In terms of the amount
of ink they'll take, and thus the correct print settings, they're pretty
much identical, but prints do look different on each, and they have a
very different "feel". Which of the three I use depends on how
"prestigious" I want a print to look, traded off against whether I want
to use the most expensive paper.
Each paper type has (and needs) its own profile, yet the printer driver
has no way of telling which of the three I'm using since the print
settings are identical. Thus, in my opinion, a printing workflow which
doesn't allow me to set a profile at print time is broken.
At best the print dialog can select a sane *default* profile, but it's
imperative that if the user "knows better" it can be overridden.
All the best

The PDF spec certainly allows for untagged objects. And so do the flavors of PDF/X.
In PDF/X-1a objects can be only DeviceGray and DeviceCMYK. DeviceRGB is disallowed. OutputIntent must be CMYK, and is simultaneously the implied source and destination profile for all content in the document (i.e. no further conversions for output, unless diverted, e.g., for proofing).
In PDF/X-3 the OutputIntent can be RGB as well. If it's RGB, then DeviceRGB is allowed, but DeviceCMYK is not. If the OutputIntent is CMYK, then DeviceCMYK is allowed, but DeviceRGB is not. Additionally, ICCBased is allowed which means multiple objects in a PDF using multiple color spaces each defined by an ICC profile - which makes them all ICCBased (an RGB object tagged with Adobe RGB 1998 is considered to be ICCBased; a CMYK object tagged with GRACoL2006_Coated1 is also considered to be ICCBased - these are all considered to be in a color space OTHER than the OutputIntent color space and will be color managed prior to output).
There is a good reason why device spaces exist in these specifications. It was simply unworkable otherwise, to require everything in PDF destined for print, to be ICCBased. While on the other hand, requiring an OutputIntent makes sense for a PDF that's intended for output on a particular device.

Sure.
What is not allowed in a PDF/X-3 framework is DeviceRGB and DeviceCMYK at the same time. For one it usually doesn't make sense. For another there isn't yet a mechanism in the spec for multiple instances of OutputIntent, on a page by page basis, for example (implying a single print job, containing pages with more than one possible print destination). This is being worked on, however. What you are talking about is a case where there aren't multiple physical destinations, but multiple virtual ones by virtue of the entry color space into the black box. And so I can see how this newer model might be applicable on Linux.

I see that this thread has been expanded to some additional lists and these
folks may not know what this is really about since they are coming into this
in the middle of the thread and just to make sure that they understand where
this is coming from here is a little back ground. This started on the email
list for the OpenPrinting group which is part of the Linux Foundation to
discuss how color management should be handled in the new Common Print Dialog
(CPD). This was quickly expanded to the OpenICC and GutenPrint email lists
since these three lists are the primary communications points for those
working on open source printing and color management. The reason that we are
hashing out these OS/X, ColorSync issues in this thread is that we don't want
to repeat the same mistakes on our open systems as we add color management.
The issues Edmund brings up involve ColorSync, various vendor supplied OS/X
printer drivers and perhaps certain applications (Photoshop has been
mentioned). None of these are open source so the open source community can't
be of much help other than making sure that we don't make the same mistakes on
our systems.
However I think we got a little side tracked and I think we need to refocus on
the original purpose of this thread (IE. how to handle color management in the
CPD). The main thing we should get out of this thread is that there needs to
be a print path that allows for convenient printing of profiling and
calibration targets as well as prematched output so that photographers and
color experts/consultants can do their work without having to jump through all
kinds of (perhaps hard to find) hoops. At the same time end users should not
even see these CM related settings unless they pull up a special part of the
UI that is intended for advanced color management savvy users.
There are clearly two use cases here:
1. Your average user - the vast majority of all printing - KISS principle
applies.
2. Photographers, color experts...
These are very different use cases and they fundamentally conflict with each
other. #1 requires that the UI and work flow be as simple as possible - it has
to work for even the most naive user - where as #2 requires a high degree of
control and a high level of user expertise. I think the tension we are
seeing in this thread is about the conflict between these two use cases.
I also agree with Edmund that it should be possible to allow saving named
presets. The current design of the CPD does this so at this point I think
this is a non-issue for our open systems design since it is already included.
Edmund also mentioned vendor branded media and the fact that much of what we
see in the vendor supplied drivers is designed to force users to purchase that
branded media. This is spot on since in many cases the printer vendors make
almost no money on the sale of the printer (at least on consumer level
devices) but make up for that in spades when they sell their expensive high
profit margin media for the printer. A user might spend only $100 to buy a
consumer level printer but over it's life they might spend 10 or 20 times that
much on paper and ink. That is where these vendors really make their money.
We should not let this get in the way of making sound design choices like it
appears to have on closed systems.

Of course right now we don't have any open source *toraster filters that are
color management aware and the only reasonable way to drive a DeviceN, where N

on the new pdftoraster filter to add CM support shouldn't it be capable of
doing DeviceN separations if it is supplied a DeviceN output ptofile? After
all we have CMMs (LCMS) that support DeviceN profiles so it should be fairly
simple for the new pdftoraster filter to generate the correct separations if
the device profile is a DeviceN profile or if the PDF spool file has been
prematched using a DeviceN profile. What happens now if CUPS gets a PDF spool
file that has been prematched to DeviceN? Does it fail even if the device
supports DeviceN and the separations are correct for that device? Or does it
convert it to some other format like CMYK?
I thought that GPLin was driving Epson printers as DeviceN devices. But I may
not have that correct. Alastair care to comment?

Again almost no one here is using the hardware vendor supplied drivers. So I
don't think it matters much what they do. Our GutenPrint driven printers will
continue to support DeviceN and CMYK print modes (even on low end devices)
regardless of what the hardware vendors choose to do other than refusing to
supply documentation for the printers communications protocol. Some vendors
have been refusing to supply this documentation for a long time but these
vendors end up not having much penetration into the FOSS market so they are
seeding this market segment to those vendors that supply the documentation
needed to write open source drivers.

You have that correct - GPLin does indeed do DeviceN for Epson printers,
and includes a "printdevicen" utility to print a multi-channel TIFF in
raw mode. You still need some way to get your data into DeviceN raster
format in the first place, of course - so far I've used it just with
multi-channel Argyll targets for experimenting with linearization. In
CUPS terminology, it's analogous to rastertogutenprint, and you'd still
need a DeviceN-capable pdftoraster.
Which brings me to one difficulty we have with DeviceN profiling -
there's currently no way as far as I know, to create DeviceN profiles
without using commercial software on Windows or Mac. Don't get me
wrong, I'm not a particularly staunch FOSS purist - but the cost of such
specialist software is a significant barrier-to-entry.
All the best,

It attempted to support them - it just didn't *work*, thanks to a few

A lie? As in, an intentionally false statement? That's an interesting assertion. I know for a fact it's possible to print profile targets reliably on Windows. There are other problems on Windows, but reliably printing profile targets and prematching color without ICM becoming involved is not one of them, because it is not aggressively invasive like ColorSync. Those are the problems I'm referring to.
My entrance to the thread was to lend my perspective to Linux dvelopers on avoiding what I consider to be major flaws with printing and color on OS X. Subsequent posts have been responses. These are not new complaints. Multiple forums including Apple's ColorSync User's list and support forums are littered with such complaints.
There isn't a mechanism for relaying perceived (or real) architectural flaws with Apple. Doing so on bug reporter consistently yields "works as intended" responses from engineering. I know because I've been down that road already.

I agree with Michael on all points.
The existing user experience is broken. A different user experience should be employed. But I think we need to be very conscientious about both the next user experience and developer experience, if things are going to be changed yet again. A huge, huge, huge problem on OS X is that things keep changing. Such change + very limited documentation has been a huge pain point for developers, and is a contributing factor to their inconsistency.
And I agree with Michael, in particular, on his first two paragraphs. Duplicative selection of media/color mode/resolution, then having to do this yet again with the profile selection, makes errors possible where otherwise there would be none (at least not UI induced). For some time it has been possible to include such device condition information into the profile as metadata, so there should be room for an application to specify a printer profile, and for the system to figure out what the driver settings should be to replicate the print condition needed for that profile to be valid.
Two things that emphasize a continuing need for application prematching capability:
a.) Black point compensation in ColorSync has functioned incorrectly since it was implemented. In an ICC v2 context, BPC is required. Perceptual rendering is inadequate. So is it working on 10.6? I don't know.
b.) Only the Apple CMM is supported in the print architecture. It's not possible for an application to ask for another CMM be used by CoreGraphics for printing purposes. This means application prematching is a required workflow.

This is something that I can generally agree with. One of the goals of the
Oyranos project is to facilitate exactly this kind of user experience. I also
think this is what the CPD is intended to support in the long run. The key
points are:
1. A very simple printing UI that hides most things color related.
2. In general all (non-target, non-prematched) CM is handled on the back end
and color is managed using ICC profiles.
3. The driver vendors will specify (and supply if needed) the default profiles
used by their device.
4. Users/admins have complete control over things like which profiles are
installed and related settings so that the back end and how it selects and
uses profiles can be configured by the user/admin.
5. Apps that need to do prematching or that are used to print targets will
have a simple API available to disable back end CM for their print jobs.
Of course at present almost none of this is in place in the non-OS/X world
(the following is FOSS specific).
#1. The CPD with proper PPD files will do this right now but none of the
existing PPD files are setup for this type of work flow.
#2. CUPS has the ability with proper *toraster filters to do #2. But the
needed open source *toraster filters still need work.
#3. This is in place on OS/X but the cupsICCProfile settings in the PPD files
are not correct for other platforms and I am not sure if this is the best way
to handle this requirement.
#4. At present is missing. Trying to configure this by using/modifying the PPD
files is at best clumsy and has lots of issues that have been touched on in
other notes in this thread and in other threads. The cupsICCProfile settings
in the PPD file is simply not designed to meet this requirement. This could
conceivably be handled by some type of interface between CUPS, Oyranos and
user land but lots of work still needs to be done in all three areas. Having
a clear vision of what the pieces are and how they fit together will make it
easier to get Oyranos, CUPS and user land tools (like Kolor Manager in KDE and
the CPD) up to speed and should allow for creating any needed APIs in the
various systems involved. I think Oyranos already has most of the APIs needed
to support user land and CUPS. CUPS, of course, has no working interface to
Oyranos in part because the Oyranos printer support is so new (GSoC 2009).
#5. This does not currently exist as far as I can tell either on the back end
(IE. CUPS and friends) or in any of the existing apps that are CM aware. On
the other hand in the open source world there are only a handful of apps that
are CM aware at all and only a subset of those know anything about ICC profiles
in the printing work flow (IE. most color manage to the display only - GIMP is
an example of a limited CM aware app). I think if there were a simple to use
well documented API for this that those apps that need it would be modified to
use it fairly quickly. Particularly since the developers of most of those
apps are members of at least one of the email lists that are part of this
thread. But the issue is that there needs to be a way to do this either
through specialized applications like PhotoPrint or by having a switch on the
CPD if no apps with this ability are available. That is I would consider
having a CPD switch for this to be a transition issue that would be removed
once we had applications available that could use the no-back end CM API call.

It is true that on Windows the user should choose a different LUT than the default which on current drivers is Epson Standard (sRGB). But the printed target isn't useless. You'll actually make a profile that works correctly, although it is restricted in gamut. However, in-gamut colors reproduce correctly.
The problem I'm referring to that does not happen on Windows is ICM getting involved when it's not asked to. That's been a regular problem on OS X, even if it's manifested itself in different ways.

Ah, that would be equal with the Colourmanage by System mode.
Well, as I wrote my initial response, my take was to let CPD implement and
present a UI for full colour management control. With the additional
requirements to softproofing and other stuff let me throw the question,
will CPD have a architecture to allow custom application side tabs and
windows in a style of plug-ins? Can these plug-ins be shared between
applications? It would allow for additional features like a bigger print
preview including soft proofing out of gamut marking and att that.
On the opposite, please correct me, Hal seems to favourise a API which
allowes for that advanced colour management (CM) stuff. That includes
changing of rendering intent, BPC, obtaining the printer profile for soft
proofing. How shall that UI wise integrate with CPD? In CinePaint I never
touched the Gutenprint panel. It was sub ideal (a hack) to have the colour
management dialog in advance to the print dialog. The print profile is not
known during soft proofing. The proofing profile can be different from the
print profile. I found printing dialogs much more useful, which allowed
a scalable preview. Some came even with a pager. Shall CPD show a print
preview button. Sorry if that is already discussed on the Linuxprinting
mailing list.
IMO, the current way to present toppic clouds in CPD is useable to hide CM
controls for most users, but still they are always reachable for those who
want them. Breaking consitency of print settings related to the selected
ICC profile should, if at all allowed, be indicated by a big warning.
There are situations where people try to improve their results with canned
ICC profiles by tweaking the print settings. This is something, I
regulary did in times, where I had no ICC workflow available. A way to
include custom corrections and effect profiles would be nice to have
anyway.
Effect profiles can then be used for the preferenced artistic look of a
print out.
This would more egalise the selection of a special printer just for the
style of interpreting colours and favoure individual user selectable
effects and styles. Vivid and natural is than available for all users not
just on single products. (Still media, inks and print hardware will make a
differencs for handling, eveness, gamut, UV stability and so on.)
The abstract class of ICC profiles, combined with a profile manipulator or
a traditional colour correction curves panel with additional sliders for
HSV manipilations which saves abstract ICC profiles, can then be used
to do colour tweakings.
Abstract profiles are almost not a path for colour professionals to get
1:1 output or relyable TAC reduction and so on. Thats something for the
device link class of profiles or special and thus selectable CMMs. Beside
that custom CMMs might help in the future on the artistic side too, e.g.
per image gamut mappings.
Effect profiles are part of the print dialog on osX. I do not know about
Windows' native dialog.
Now we get back to early versus remote colour binding.
This all requires early colour binding and thus CPD has to locally
render final values. In a more complicated workflow, CPD could tag the
content with appropriately manipulated profiles for remote applyance. With
more resources I could imagine to get effect profiles reproduceable
working in a remote and late colour binding scenario. But that would
certainly require much support and man power. This later path is unlikely
to get implemented in the forseeable future.
To summarise:
a) Effect profiles are cool and very flexible.
b) Device link profiles and selectable CMMs allow for advanced
professional and artistic stuff.
c) The above is all difficult to get remotely working, so colour
conversions should typical apply already in CPD.
d) Average users expect to select print effects at time of printing and
thus in the print UI.
e) If CPD does not care, vendors will take their chance and fill that
niche to provide better than average results.
d) Vendor intervention in the CM workflow is undesireable as it will
invent lots of different solutions and potentially break things.
Given with all the above I want to reiterate about the three basic CM
modes in CPD (Hal suggested to have only two):
* Colourmanage in Application (early colour binding).
CPD is considered as part of the application infrastructure and not
stand allone. The name CPD, Common Printing Dialog, implies this to me.
So early colour binding has typical to happen in CPD. For applying of
effect profiles and other advanced CM technices, which we do not (yet)
know how to simply transport over PDF to a remote host, this early
binding mode is the preference.
* Colourmanage by System (late colour binding), or colour process remotely
is the right default with vendor supplied ICC profiles. In the
perceptual tables can a pleasing rendering be expected.
* No Colourmanagement, print raw values. A exception for printing colour
targets, special cases, e.g. dot by dot printing, and when the above
does not suffice.
That written I do not at all want to fix the modes names, but they should
be transparent to the user as they are very fundamental not only for
developers. The names and how they are exposed to CPD users have to be
discussed with the UI experts in detail.
Further the strong suggestion of Mike Sweet to hide the selection of the
final print profile can be reached with deploying technices like effect
profiles and others. This means as well that the above three basic CM
modes would loose their prominence. Perhaps the No Colourmanagement
mode resides in a expert tab of CPD. Perhaps that mode is intermediate
and switches back automatically after printing the colour chart.

Good that would omit the No Colourmanagement mode from the CPD UI. But
then a simple application, which is always available to prints to all
queues is a reuirement to point colour experts to. The application should
be able to work with all drivers. Could Photoprint take this over?

Hi all
I've been reading all posts with varying levels of comprehension, but
always with great interest.
To get back to my own concern, design of the UI for the CPD I'm going
to boil this down to a quite high level statement which expresses the
direction we believe the CPD should take. This is not only in response
to the information gleaned here, but also very much in the context of
our own convictions about the design of a print dialogue for all users.
So:
*If printing doesn't exist, colour printing also doesn't exist. Terms
and concepts like colour management and ICC profiles have no meaning
to a vast majority of users. Most users want their colour printing to
just work with no intervention required.
*Successful colour printing is as much about media as it is about the
ink which goes on it. This means that for successful colour printing
from the CPD a holistic picture of the print is required.

Agreed, most users do not need to know about techical details.
As soon as they want colour to just work, ICC colour management is the
right choice to get this done. So at least the results of colour
management are understood, and meeting of expectations regarding colour is
part of how they are satisfied with the print system.

Is it planed to omit a detailed print preview? I have seen this kind of
windows and modes in office applications, mainly to walk through multi
page documents before printing. They are very useful there.
How is the print preview integrated with CPD? Shall it work like a
button inside CPD, which calls into the main application with some
parameters to render the preview on application side? Or is it a tab?
A link to according documentation would be great.

How can we learn details about CPD presets? What makes it difficult to
dump out a CPD preset?

While the idea was provided to hide low level ICC options, I would
see it as an disadvantage to have the ICC related controls not
available and would favour to make the outlined CM controls available in
CPD through a experts only panel, which has a reset button for getting
easily to the defaults.
But if not, how can applications plug-in a own CM panel into CPD?
As well looking at Windows and osX print dialogs, there are a lot of
colour controls. These are not the expert controls you wrote about.
Nevertheless they are a big selling point for photo printers.
Delivering vivid, natural, sepia and other effects on button click
including a canned ICC profile mode is typical integrated into driver
panels of photo capable printers. Why would print manufacturers wast that
space if it would be of no need?
As well I expect most home users have a photo mode in their printing
device. They print mostly letters but from time to time as well images
and flyers. So this kind of ICC colour controls matters.
> *Let the API take the strain: i.e automatic colour control override is
> desirable and achievable.
You mean setting and freezing colour related controls as soon as a ICC
profile is selected(?) This would be the correct mode for the use of ICC
profiles. Somehow CPD has to know, which settings are colour related for
the particular driver. This can eigther be transported through Oyranos or
the profile itself, which again can be translated by Oyranos.
There will be people who complain about the missed capability to hand
tweak their colours. This is quite natural. A way to satisfy those
demand is to support effect profiles, which fits well with the point
above.

A big advantage of dumping out a preset is better supportability. With
dumped files, it is possible to send such a preset to a knowledgeable
person for remote analysis.
Cloning presets is for administrators and for sharing among people equally
useful.
Regarding ICC profiles, a preset package would need to include the ICC
profile.

At least on OS X, the API is the means to set two flags: object source and OutputIntent (destination profile and implicit source profile for device color). The application doesn't directly set these. It has to ask for it to be set via an API. And then only later if the two flags (color spaces) are correctly set, is color management disabled at the raster stage.
Putting objects into DeviceRGB/CMYK/Gray/N, instead of ICCBased color space, with a required OutputIntent could be a way to inform the system to not perform color management. But as Graeme points out it could be a different flag entirely. Also, I don't know what the print spool file format is in on Linux, so perhaps that language is more easily extended than PDF.
PDF/X-3 is just one possible model. It doesn't have to be followed exactly. But it's a good model. (I'm calling it a model because we can follow its workflow prescriptions without using the actual file format.)
PDF/X-4 which adds transparency support to PDF/X-3. As I've implemented Ghostscript based proofing for high end clients, I'm confident its transparency support works well.
PDF/X-5 implements externally referenced images and ICC profiles, which could come in handy.
PDF 2.0 spec will add explicit BPC (black point compensation) support in the file format, which means the ability to set a per object flag for BPC on or off. And that should be considered since perceptual and relcol transforms aren't ideal for most images, in an ICC v2 context. (In v4, perceptual would be the default intent. In v2, relcol + bpc should be the default.)
You may want multiple OutputIntents. Currently all of these specs use just one, following a "one PDF, one output device condition" sort of philosophy. But it's imaginable having a single print job for a small book and cover, where there are different intents for the cover, and the interior stock. Or a book that's mostly black and white but with some color image inserts in the middle of the book.
Anyway, I think in the near term PDF/X-4 along with BPC support make the most sense to me.

Abstract profiles could do these kinds of edits in the PCS. Either as an advanced panel of sliders that institute edits in the PCS - a sort of on-the-fly abstract class profile. Or a separate means of creating them and just allow a pop-up menu of selections. I like the slider approach.
I think it's important to not have effects baked into output device profiles.

I think the CPD design probably needs to be clarified for those who have not
had a chance to review the current design. The CPD has a print preview that:
1. Is always displayed unless the user says "just print" which bypasses the
UI.
2. Has a fixed size and is fairly small.
3. The preview is NOT intended for proofing since it's small size makes it of
limited usefulness for this and the apps that are used by users who need/want
soft proofing generally already have this built in or available as a plug-in
(GIMP, Scribus...).
While I am not sure that I totally agree with these design choices they are
reasonable and are a good starting point for moving forward.
For more details on the UI design see

The CPD does not use tabs. See the above link for details on why this is the
case. Keep in mind that the CPD is designed for the new PDF based printing
work flow so it expects that the app will pass it a PDF file and this is used to
render the preview. The same PDF is passed to the back end when the users
commits the print job.

Users can create CPD presets and these are persistent. A static set of
presets are also configured in the PPD file by the driver vendor so that certain
presets are vendor/device specific and always present. IE. there are a set of
presets that are specified by the vendor in the PPD file that are always present
unless a local admin has modified the printer PPD file.
I don't know anything about extracting and sharing user created presets.

The CPD is for the most part controlled by the contents of the printer PPD
file. Controls are grouped and those groups are presented to users who can add
or remove these groups from the controls that are displayed. Controls can be
in more than one group but are only displayed once. In the CPD these groups
are called tags. By enabling or disabling these tags the user can make the
CPD as simple or complex as they want within the limits of what is exposed in
the PPD file. In its simplest form the CPD only has controls to select
presets, to select the queue, to enable the selection of tags and to select
the number of copies printed along with the preview.
I believe that it is possible to have tags and controls that are not specified
in the devices PPD file for doing things that are not printer specific. This
could be used to have a Color Management tag for those controls related to
this functionality. For users who choose one of the vendor created presets CM
will likely be set to use the system default profiles and CM processing path.
Advanced users should be able to create presets for printing targets that
completely disable all color processing and other presets for certain types of
prematched printing if the back end can not be configured to correctly handle
profile selection. I think we should be able to make the need for prematching
a very rare occurrence if we can get Oyranos/CUPS and friends to work
correctly. But I think it could take some time to get all of this working the
way we want.
Currently there are no CM controls available on the CPD unless those are in
the devices PPD file (and none have this that I know of).

I agree with this. When I saw how the CPD was designed to work at the
OpenPrinting Summit in April I was impressed by how flexible and user centric
the UI design for the CPD is. IMO it is the most advance printing UI in
existence and it shows a lot of promise for moving things forward. About the
only things missing at this point are how CM should be presented and almost
none of the vendor PPD files are setup to take full advantage of the CPD (PPD
extensions were created to support these advanced CPD features and most PPD
files do not use these yet).

Admins need a way to create presets that are available for all users of a
given queue/printer. Doing this by modifying the PPD file on the server is
only acceptable as an interim measure. This is very important for the CM
related presets for shared printers in organizations that need to have
professionally configured color managed print queues. For example color
consultants/experts should be able to calibrate and profile a
printer/media/drivers settings combination and then create a preset that will
always set the printer up correctly (IE. select the correct paper tray, set
the right driver settings, use the correct profile, lock down any controls that
affect color...) and that preset should be available to any user who uses that
printer/queue. Then all users have to do to get a hand configured color
managed print is to select that preset.
This would be useful even for local print queues. For example my wife likes
to print photos and complains about how complex it is to get the same quality
of results that I do. Her complaints are justified IMO since it requires
jumping through hoops that are difficult for non-color experts to understand.
If I could configure a preset that did everything to insure that the correct
things would happen I could label that preset something like "Print Photos on
XXX Paper" and all she would have to do is load the correct paper into the
printer and select the custom preset. I am sure that this would make my wife
happy and it would also mean that I would not have to assist her every time
she wanted to print some photos (which I think would also make her happy).

Can the effect profiles be applied in a late binding style - remotely

A)
One alternative would be to replace the object ICCbased profiles with ones
which contain the abstract effect(s):
object space (sRGB) -> abstract effect(s) (CIE*Lab)
==> new profile (replacing sRGB)
If the input (object) profile has several tables, the unused ones can be
omitted using only the wanted rendering intent. Its like a device link
with a output colour space of CIE*Lab. Some refere to it as backing in a
profile. It would need to iterate over all PDF objects and replace their
ICC profiles. The intermediate replacement ICC profile can be considered a
additional conversion even if it does not alter any colour values. This is
due to the interpolations during the profile table creation.
B)
An other alternative is to put the effect profile(s) into the job ticket
for later usage during object colour conversion:
object space (sRGB) -> abstract effect(s) -> device space (printer)
But that largely depends on the spoolers capabilities. From a CM point of
view that would be ideal, as it allows to follow a as few as possible
conversions strategy.
The colour binding can be moved from a early to a late stage with both
alternatives. As well the output intent remains untouched as Chris Murphy
suggested. ... feature complete

I agree it's a bit of a challenge to make this happen with screened data, but I'd wonder why it's screened if it's not meant for immediate output?
If it's normalized to output space but NOT screened, an "effects profile" or "abstract" profile is relatively easy:
devicespace >PCS > abstract profile > PCS > devicespace
If the supported precision is at least 16bpc I'd consider it pretty much a non-issue. (ACE is 32bpc float precision.)
If it is screened, well, it's still absolutely doable but it's basically a 1-bit TIFF style workflow. I think there are probably other priorities, but I'm open to discussing this.

I think if the precision level of the conversion is high enough, quantization is a non-issue. But there might be gamut issues...including abstract profile induced posterization.

A soft proof that incorporates the abstract profile effect in the chain, as well as the output device profile, has clear benefits in avoiding undesirable gamut mapping problems.

Devicelink workflows are inherently extremely fragile, as presented by the ICC spec. Only a creative solution, that is not obviously prescribed by the ICC spec, can work around such problems. This may very well include *mandatory* PSID support (although I have yet to see explicitly documentation for this tag), or some mechanism for referencing at least the destination profile for the purpose of tagging the resulting data correctly once converted. The effect of an abstract profile would occur before this, but interestingly enough the aggressiveness of the abstract profile in terms of a saturation boost very possibly will affect the rendering intent.
i.e. with a null abstract profile, and use selects RelCol+BPC, but then decides that an abstract profile boosting saturation is preferred, might necessitate the perceptual intent in order to better manager the larger percentage of out of gamut colors as a result of applying the abstract profile that boosts chroma.
*shrug* It's an interesting challenge. The more advanced and imaginative the workflow gets, the more we run into problems with the ICC spec.

It's fairly well established that printers do not need more than 8bpc. The challenge is getting the correct 8bpc. And this is most easily achieved by an intermediate space with 16bpc or higher. (e.g. ACE is 32bpc float for some time now, previously it was 20bpc integer regardless of source bit depth). So yeah, any conversions shouldn't be considering 8bpc at all. 16bpc works in most instances, and 32bpc float is just going to totally clobber the issue altogether so I'd work toward a 32bpc float model. And just totally eliminate any question about whatever serious torquing of color spaces may be instituted (by the pipeline or the user or the driver or LUTs or profiles, or whatever).
So *if* there is a debate it's between 16bpc integer and 32bpc float, not 8bpc or 16bpc.

I completely agree 16-bit can be a essential quality improovement. Its
like looking through glass or no glass. If someone has no problems while
looking on a surfaces through glass then be it.
If you want the best output in regards of fine shades, be warned of 8-bit
source and 8-bit print files.
Printers capable of showing very smooth transitions of shades, are able to
expose stepping coming from 8-bit source material since years. This is
visible in smooth sourfaces like water, blurred image regions, sky and
other gradient alike image regions. Dithering is a poore cirumvention and
possibly sand for your eyes. Others may be trained and see the artificial
habit of the banding artifacts coming from the 8-bit source material.
Keep in mind that most advertising material, arts prints, arts
paintings behind thick glass and of course monitors have easily
conditioned many peoples eyes to be very tollerant.
That said, for office paper, news paper and smaller than post card size
prints 8-bit might be enough. This maps to the majority of printed
imagery, but not to all printing demands.

I just remembered something, someone mentioned aproaching Nokia but getting
shut down. While the CPD might be a hard sell for nokia, which is primarly
interested in Meego as a phone os, one might be more successful with Intel
which is mostly interested in Meego for netbooks (and or Moorestone based
phones). The Meego stack is mostly standard Linux (X11, kernel.org kernel,
CUPS + foomatic) with QT for a widget framework. It shouldn't (easy for me
to say) be much harder to support Meego than say KDE. Since the stack is
young getting it in widespread use, at-least within Meego apps, should be as
simple as getting into the environment.

I think that this assessment is basically correct. Intel/Meego might be more
likely to respond to this than Nokia. Also the current CPD is tied to KDE and
I think it would be better to decouple it from KDE and make it a
generic/native Qt app. This would in the long run make it more attractive to
Nokia/Intel and other Meego vendors while at the same time supporting KDE. If
anything this should result in wider use of the CPD.
I have a contact at Intel who is part of the Meego team. I am not sure if he
can help but I will contact him to see if there is any interest. Probably
will not go anywhere but it can't hurt to try.

guys,
yes, I also have a contact on the meego platform.
however, we have to be careful here what we get into.
the cpd is designed for desktop computers, we did wake up to
the rise of netbooks and support those small screen sizes,
down to 800x600. but positively the design is made for
either a gnome or kde desktop environment with mouse/trackpad
input.
- anything handheld is not in scope;
- touch input is not in scope;
- environments where the distributor decided that the standard
kde/gnome desktop environment is not suitable and build their own
UI shell, are very much a grey-zone. case-by-case in/out of scope.
doing any (combination) of the above is simply another branch in
the design, which is work that then simply needs to be commissioned,
from design + usability to implementation + integration.
