ABSTRACT:
A color value classification system particularly suited for use in printing procedures based upon the cyan, magenta and yellow primary colors, including both traditional and digital color separation methods, as well as all types of other printing systems. The classification is based upon four groups of five colors each, in which half of the colors are the substan- tial complements of the remaining half. The twenty colors are derived from the blending of the basic primary colors known as process colors in the printing industry.
