Abstract
A method and a system for generating a dither matrix calibrated to a desired tonal response. The method and system comprise generating a dither matrix with a predicted tonal response, measuring the actual tonal response, manipulating a cumulative histogram for the dither matrix in response to the actual tonal response, and inputting the cumulative histogram to a dither matrix generation program to generate a dither matrix that conforms to the cumulative histogram. Other systems and methods are disclosed.
