[Openicc] colord Printing Plans, CPD and Gutenprint role of PPD

[Jan-Peter Homann]

Hello Edmund,
My interest in this discussion is to establish a transparent workflow 
for colormanagement from document ICC profile to driver setting ICC profile.

I believe, that solutions like e.g. Oyranos or colord could deliver a 
communication layer between the colorsettings of the document which is 
been printed and the actual printer driver setting.

I´m fed up with the color infrastructure of Mac OSX, which I´m using 
since 20 years. I also don´t see that the ICC itself, will define such a 
transparent color infrastructure, because obviously important ICC 
members like vendors for operating systems or closed source printer 
drivers have no interest to do this.

I believe, that the OpenSource community has the potential to solve this 
puzzle and to create an ecosystem of printer drivers, applications and a 
colormanagement framework, which could lead to similar results under 
LINUX, Mac OS X and Windows (inside the ecosystem..)

I think 3 to 5 years to reach this goal is quite optimistic but possible...

On the other hand, I´m learning that taking part on OpenICC as a enduser 
/ consultant is sometimes quite time consuming and leads to 
missunderstandings...

E.g from my perspective, it is 100% clear, that driver settings and 
assigning profiles to a driver setting is best done in the driver and 
than communicated from the driver via the "color infrastructure layer" 
like e.g. Oyranos or colord to the place where the color transform  
takes part.

1) Create a driver setting
2) Assign a profile to the driver setting in the driver
3) make the driver setting choosable in the printing GUI (e.g. CPD, GTK+ 
Chooser or individual UI)
4) Deliver a mechanism, that the assigned profile of the choosed setting 
is communicated via Oyranos / colord or whatever to the engine where the 
color transformation from document ICC to printer ICC is done.

It seems, that I´m not able to explain or convince the developers here, 
that this way makes sense...

On the other hand, the developers at OpenICC , seem to prefer some ways, 
which I don´t understand
- the magic of CUPSicc...
- the magic of a fuzzy match through Oyranos

Hopefully I learn through the mailinglist, to fix the obvious 
communication problems between me and the developers here...

Edmund,
Did you understand now more my interest in the discussion ?

Best regards
Jan-Peter
