Our print ad run goes live Tuesday and I must convert the RGB comps to CMYK tonight. I'm worried converting will crush the shadows and lose the punch. Tell me the exact sequence to convert while preserving contrast, which sliders to watch, and a quick proofing move I can use to convince the client the CMYK version still reads as bold as the screen file.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.
