Abstract
A method adapted for implementation in a computer system for correcting and half toning color data in a list of colors is provided. Starting with the first color in the list, color corrections are performed. Using traditional half toning methods, descriptions of the resulting printable dots for each position in the halftone matrix for that color are determined. Color corrections and half toning are repeated for each of the colors in the list. A lookup table is compiled. As each pixel of the image from which the list of colors was compiled is encountered, the printable dots are determined by reference to the lookup table.
