1. An improved process for transforming a first form of color representation in a first color space and a second form of color representation in a second color space using look-up tables to represent said color representations consisting of the steps of: a) transforming all colors in said first form of color representation using said look-up tables to said second form of color representation; b) using said look-up tables to transform all colors in said second form of color representation which have been transformed during said first transforming step back to said first form of color representation; repeating said steps a) and b) a plurality of times; comparing the results of each subsequent transformation to the results of previous representations; and where said results do not compare, altering said representations so as to compensate for said non-comparison; and retrying said transformations steps until said transformations do not alter said results.
