METHOD AND APPARATUS FOR COMPENSATING FOR DOT GAIN IN STOCHASTIC PRINTING.

摘要

A method of compensating for dot gain in stochastic screen files to be printed on an output device having a predefined resolution comprising: receiving continuous tone CMYK files at a resolution less than the resolution of the output device; screening the continuous tone CMYK files to produce stochastic CMYK files at a resolution less than the resolution of the output device; expanding the stochastic CMYK files to have a resolution that is equal to the resolution of the output device wherein the expansion causes each dot in the stochastic CMYK file to be represented at a number of subdots in the expanded stochastic CMYK file; and selectively removing a number of the subdots in the expanded stochastic CMYK file to compensate for dot gain when the expanded stochastic CMYK files are printed.
