Back in the ancient computer days, I had a H/P Deskwriter that only had CMY (single cartridge) and it was the cat's butt then. Color work was not brilliant but I never had a bit of trouble with it. Later, I "upgraded" to a newer CMYK unit and it gave me nothing but grief! So much so that I vowed to never use another H/P product ever. And I haven't. In theory, CMY should produce perfect colors including black and it does so in traditional subtractive photographic processes just as RGB works in the additive processes. But it does not in the print process where every color media needs a black "kicker" to really make it work.
