System and method for color dither matrix creation using human-vision-system gray matrix with cluster radii

摘要

A system and method for creating dither matrices for printing in color. The disclosed method shows how to construct arrays for cyan, magenta, yellow, and black primary color printing for which only a single calculation using the cost function is involved. The disclosed method computes only a single dither array. Once the first array is generated, the computer software program creates the other arrays by translating points of the original array to corresponding points in the secondary array. In one embodiment translation is performed using a random number generator. In alternate embodiments, translation is performed by inversion and shifting of the first array.
