I need to find out how to calculate the proper Cyan, Yellow, Magenta, and Black values from Red Green Blue input to produce plates for color printing. I know the old standard 1-[RGB] = [CMY], but I wouldn't mind a somewhat more accurate method for that, either. My biggest problem is that I don't know exactly the best way to figure out how much black there should be. I know that there should be some smaller quantity of black than the other three, and that it should then be subtracted from them, but I'm not sure how much less than the smallest of CMY. Thanks in advance, and please respond via email as I don't follow this newsgroup.
