Hi Henning Hraban, I contacted three print shops and they demand three different color profiles, one of them prints on "100 % recycling paper" with an uncoated profile. The other two use ISO Coated v2 300% and Coated Fogra 39.
Being online shops I think they will complain if not the right profile is provided. But anyway. I will summarize: Am 17.02.20 um 16:35 schrieb Henning Hraban Ramm: > That means you should keep your photos in (profiled) RGB.

All my images should be profiled. I think I can do this in Gimp. > For type and logos I still rely on (device dependend) CMYK colors and > my experience how they’ll come out in Euroscale printing. Device depended means what? I did this to convert our RGB corporate colors to device depended CMYK: transicc -i sRGB.icc -o Fogra/Iso-whatever.icc But what shall I do with the logo? It is a RGB SVG. Do I understand you correctly that the best would be to ask someone with Indesign to convert it to CMYK with the above cited profile chain? Or shall I tell the designer: These are the values I need as CMYK, just do it. > Colors that you define in TeX or Metapost are a different problem.

I do it like this: \startmode[fogra39] \definecolor [hs-logoblau] [c=1.000, m=0.735, y=0.279, k=0.160] \definecolor [hs-dunkelblau] [c=0.844, m=0.544, y=0.070, k=0.000] \definecolor [hs-hellblau] [c=0.468, m=0.220, y=0.086, k=0.002] \definecolor [hs-orange] [c=0.127, m=0.832, y=1.000, k=0.042] \setupcolors[cmyk=yes,rgb=no,] \setupbackend[ format=PDF/X-3:2003, intent={Coated FOGRA39 (ISO 12647-2:2004)}, ] \stopmode I like your thought that all profiles are more or less the same. That would mean that my designer could convert our SVG logo and our SVG icons to Device-profiled CMYK-PDF and I am good. Thanks for your help. juh ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
