Client proofed it in RGB, I printed it in CMYK, rice was purple
Last month a restaurant owner approved a menu proof where the rice looked white on his screen, but the file had an RGB value that shifted to a weird lavender once I flattened it for print. He called me furious at 7am asking why his signature dish now looked like a science experiment. Has anyone else had a client insist their monitor is the final authority on color?
Did he ever tell you what monitor he was looking at it on? Because that is the whole ballgame right there. A cheap laptop screen with the brightness cranked up will show you a totally different white than a color corrected display, and no two screens in his restaurant are probably the same either. Did you ask him to compare the proof on paper before signing off, or did he just eyeball it on screen and give you the thumbs up? Next time make him sign a physical proof, that is the only way to end this argument.
