Hello everyone,
I'm about creating a DIN Lang Folder brochure with ConTEXt. I got everything set up the way I'd like it to. Now that I'm done with the work, I've been told the output pdf should have a CMYK Color profile embedded for the on demand printing service to be able to deal with the file...
I am unsure what steps I have to take to make my output pdf compliant with CMYK. I don't even know how I could verify it does indeed have CMYK. Evince doesn't seem to show that info...
So if anybdy of you could give me some hints, that's be wonderful.
Cheers De Benny
Hi Benny, if you can read German you might find some hints in my articles about creating din lang folders https://www.hasecke.eu/post/werbemittel-mit-context-gestalten/ On colors read the second part: https://www.hasecke.eu/post/wie-wir-bei-hostsharing-mit-context-arbeiten/ Search the mailing list for color profile questions because I had to ask often to make my things work. ;-) The wiki contains some hints, too. What you can do is to create a mode like this: \startmode[fogra39] \doiffileelse{CoatedFOGRA39.icc}{}{\farbprofilnichtgefunden} % This will be printed in log if context does not find the profile for % some reason \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 If you call context with --mode=fogra39 you will get these color definitions and the defined pdf format with the right profile (intent). If you download additional icc profiles (eg. the fogra one is missing in the context distribution) put them here: context/tex/texmf-local/colors/icc In this folder they won't be overwritten by an update. There are some limitations in ConTeXt concerning colors as embedded images are not converted, so RGB images are converted only by the print shop during printing, which can lead to strange results. I think the only way to control the output is to convert all images to CMYK by hand. By doing this you can modify them to get the best results. I hope that helps juh
