Method, system, and program for halftoning data for rendering in a multitone output device

摘要

Disclosed is a method, system, and program for halftoning data for an output device capable of rendering multiple intensities. Input values are received. For each received input value, the input value is used as an output value if the input value is a predetermined value. Otherwise, if the input value is not the predetermined value, then the input value is halftoned to produce an output value used to render one of multiple intensities. This allows the use of data intended for bi-level printers that may have already been halftoned.
