[Openicc] Control slug for print outs with metadata about colormanagement settings

[Jan-Peter Homann]

Hello Lai Uwe, hello List
Thanks for your reply.
Lets assume, we have a system with e.g.
1) Oyranos
2) Scribus
3) Ghostscript
4) CUPS
5) Gutenprint

All this parts have to be coordinated for the correct usage of 
ICC-profiles and printer driver settings.

So far as I know, we have currently no agreed architecture, for cross 
application coordination of color settings and color management 
policies. It is currently the user, who decides where to use ICC 
profiles and where no conversion should be applied to avoid unwanted 
color conversions.

The control slug for the print out with color settings would be a first 
step for transparency of colormanagement in the printing chain.
So I would be very glad to get statements from
2) Scribus
3) Ghostscript
4) CUPS
5) Gutenprint

If there is a way to make the current color settings / driver settings 
available for generating a control slug (or additional color 
configuration page for  print pipeline).

Best regards
Jan-Peter
