Compensation for coverage area distortion in high resolution printing

摘要

This invention relates to a method and system that compensates for coverage-area spread distortions that occur during the reproduction of artwork having solid ink coverage. The method comprises characterizing the reproduction system on which the artwork will be printed, and modifying the artwork by causing a spread or choke to one or more selected graphic elements of the artwork by an amount determined according to the results of the characterization step. One way of causing a spread or choke is to mark an element for later modification of its perimeter, and another is to directly modify the element's perimeter. Reproducing the modified artwork on the reproduction system reduces the coverage gain effects. <IMAGE>
