ABSTRACT:
To convert the multiple-bit-resolution intensity information for a color component of a given pixel into the ink-on or ink-off command required to control a printer, the source values for different pixels are compared with thresholds in a "dither matrix" of different thresholds for different pixels, and a given pixel is printed if the source value exceeds the dither-matrix value for that pixel. Different dither matrices are employed for different color components, with the result that lighter-color areas have a smoother appearance than they would result if a common dither matrix were employed for all color components.
