CcMmYK color model shades of cyan or magenta on the pure CMYK ink configuration. Usually when printing a dark color the printer will saturate the area with colored ink dots, but will use fewer ink dots to create the effect of a light color. The result is hard to notice with yellow because yellow is perceived as a very light color. However, the individual cyan and magenta ink dots will stand out in a sparse pattern due to their darker color against a white background; the result is undesirable when it is noticed. By using light cyan or magenta, the printer can saturate
CMYK color model method that has emerged for the case of halftone printing is to treat each tiny overlap of color dots as one of 8 (combinations of CMY) or of 16 (combinations of CMYK) colors, which in this context are known as "Neugebauer primaries". The resultant color would be an area-weighted colorimetric combination of these primary colors, except that the "Yule–Nielsen" effect of scattered light between and within the areas complicates the physics and the analysis; empirical formulas for such analysis have been developed, in terms of detailed dye combination absorption spectra and empirical parameters.
