Hi there,
I want to produce a certified pdf with cmyk + spot colours, preferably with a Ghent profile. So far I've tried GWG_SheetCmyk_2015 CMYK + RGB (as Illustrator refers to spot colours as rgb) but it gives me an error after preflight. So which one should I look for? I'm using Pitstop Pro 13 and 17 on OSX 10.10.5. Tia.
