What is CMYK color?
CMYK stands for Cyan, Magenta, Yellow and blacK, which are the common ink colors in 4-color printing processes. In a pure CMYK system, the black is unnecessary, and the other three colors are the exact inverse of Red, Green and Blue. Since real inks never quite work this way, some adjustments have to be made. The main one is adding black, since mixing cyan, magenta and yellow inks usually results in a muddy brown rather than a black. PSP 5 can perform CMYK separations, which give 4 grayscale images which correspond to the four ink colors. Details of the separation process can be controlled through the File/Preferences/CMYK Conversion Preferences dialogs. For colorizing pictures, if you need the Hue, Saturation and Luminance values for Cyan, Magenta, and Yellow, Mark S.
