Mapping highlight colors to black-and-white textures

摘要

A method for mapping highlight colors to monochromatic textures is provided. It includes reading an input highlight color having a highlight color amount and a base color amount. The highlight color amount is measured and the base color amount is measured. A halftone cell (50) is defined having a plurality of output regions with corresponding output states. The output states of all the output regions are controlled in response to the measured base color amount. The output state of at least one but less than all the output regions is controlled in response to the measured highlight color amount such that the output state of at least one but less than all of the output regions is controlled by both the measured base color amount and the measured highlight color amount.
