摘要： Provided is a printing system comprising a printing mechanism for applying ink to a substrate using a plurality of print colors. Also included is a computer readable media storing an image and instructions for generating entries in a variable resolution lookup table for use in performing accelerated color conversion of the image. Also included is a lookup table generator configured to divide the lookup table into a plurality of areas, and set a density of lookup table entries in each of the plurality of areas based on overprint combinations of the print colors. The density of entries is varied from one area to another. Also included is a color conversion controller configured to utilize a lookup function to retrieve one or more lookup table entries and to provide printing color space coordinates based upon the one or more lookup table entries to the printing mechanism.
