Dither mask generation with calibration-independent number of threshold levels

摘要

Calibrated dither masks adaptable to most printers are constructed in such a way that the threshold values can be adapted to a printer so that said printer can print the originally intended number of distinct tone levels. This adaptation can be done computationally so that the time it takes is not prohibitive. Furthermore, the resulting calibrated dither mask is such that there is no need for a tone reproduction curve in the halftoning process.
