Color system conversion table generation method, color system conversion table generation apparatus, and non-transitory computer readable medium for converting coordinate value between device dependent color space and device independent color space
Abstract:
A method for generating a color system conversion table includes generating a third color system conversion table in which a color specification value of a CMY color system including three primary colors of pigment is an input and a color specification value of the device independent color space is an output, wherein the number of input lattice points of the third color system conversion table is determined such that the number of input lattice points of the third color system conversion table decreases as the gamut size of the printer decreases.
