Abstract

Halftones, or periodic cluster dithers, are point-to-point, contone pixel to halftone dot, conversion processes. This paper describes an approach to achieving accurate halftone reproduction by using the errors caused during the scan conversion process without comparison to the source pixels and maintaining the point-to-point scan conversion paradigm. Two types of density errors encountered in the halftoning process are considered. 1. An error describing the difference between the input pixel value and the halftone threshold value. 2. An error describing the difference between the density level of the output data and the reflection density of the ink or toner on the page.
