Right, I get that (although I see why my reply might imply I didn't), but "aptitude why" is not acknowledging that dependency, which interested me...

Actually more accurately I tried CMY, not CMYK. It made no difference. What is the K of CMYK? Cyan, Magenta, Yellow, Kick-Ass??? Is there any reason I should expect CMYK to do better than CMY or RGB?
