Re: Spot conversion to CMYK Reply #15 – November 24, 2018, 10:43:39 AM I generally use whatever application I have the file in. If it is a print ready (supposedly) PDF I will just use acrobats preflight and convert to CMYK, never had a complaint and if they did we would explain that the file needed to be converted for press.It is curious though how apps handle the conversation of a pantone to CMYK. Just noticed it today, I am setting up a large calendar in Indesign, used the companies pantone colour 221 U. When in Illustrator working on one of the vector images in the calendar I converted the pantone and got a CMYK makeup. When I converted the same pantone in Indesign it was a completely different makeup, not even close. Bizarre that applications from the same company do not seem to use the same method for converting got CMYK.
