Hello all,
I´m happy to hear that the proposal was accepted. I plan to help where I 
can. I read the proposal and the links provided by Till.
One central point to solve is the association of a driver setup with an 
ICC-profile. A very smart approach to this task was already discussed in 
the list is as following:
- All necessary informations to setup the driver are encoded in the 
profile incl. e.g.
- per channel ink limiting
- per channel calibration curves
- resolution
- rasterization

This allows an easy exchange of profiles between users and secures, that 
driver setting and profile will match after the profile is imported.

 From the GUI, the profile chooser will be the center for all color 
relevant options.

During profile generation we need a communication layer between the 
driver (e.g. Gutenprint) and the profile generation software (e.g. 
ArgyllCMS). This communication layer pulls the driver setup, wich was 
active during printing the testchart and writes the information into the 

I would prefer a solution, which would be independent both from drivers 
and profiling solutions, so that it could be e.g. implemented into 
Oyranos or g-c-m with may be Gutenprint and ArgyllCMS being the first 
solutions to support it. Even if the profiling solution would not 
support it directly, such information could easily integrated into every 
ICC-profile afterwards through Oyranos or g-c-m.

The main question for prototyping would be to find a first driver 
developer who will be able to support the project:

Do You think Gutenprint would support such a project ?
If yes, what will be a timeframe for Gutenprint being able to import a 
complete setup with one file ?

Do you think, that the ICC automated workflow group would support the 
project with an outlook to be an official applied ICC tag ?

Best regards
