ABSTRACT:
A system, method, and program for generating a color rendering dictionary file or look-up table for an equivalent device dependent four component colorant combination for a given printer from a given device independent three dimensional color space. First input parameters are comprised of varying percentage amounts of an additional fourth colorant and corresponding measured color values for varied percentage amounts of the additional fourth colorant. Second input parameters are comprised of varying percentage amounts of three base colorants and corresponding measured color values for varied percentage amounts of the three base colorants. Percentage amounts of the three base colorants (three colorant values) for each varied percentage amount of the additional fourth colorant are determined from the sets of measured color values. The percentage amounts of the three base colorants with the additional fourth colorants are determined, such that the fourth colorants are equivalent to the varied percentage amounts of the base colorants. The determined four colorant values are then correlated with the measured color values of each of the equivalent varied amounts of the three base colorants. A look-up or color dictionary is used to find correlated four colorant values for any given color.
