Remarks

According to Wikipedia, CMYK (short for cyan, magenta, yellow, and key) is a subtractive color model used in color printing. This color model is based on mixing pigments of the following colors in order to make other colors: * C = Cyan. * M = Magenta. * Y = Yellow. * K = Key (Black). CMYK is the standard color model used in offset printing for full-color documents. CMYK, or four-color printing, generates a good final printout with excellent contrast.
