ABSTRACT:
A system for converting RGB color signals to CMY or CMYK color signals, such as to operate a color printing apparatus, utilizes three separate electronic look-up tables. Each look-up table allows inputs of RGB signals, which are applied to a three-dimensional space. Each point in the space represents an output for one CMY color signal, and each look-up table is dedicated to one CMY color output. Each look-up table emphasizes one particular RGB color, by providing a higher resolution of inputs along the axis for that color.
