Abstract

This article describes a new process for digital color halftone reproduction suitable for CRT display as well as for printing. This process eliminates the formation of moire patterns, and the human intervention that is common in color reproduction work. Over the last years, sophisticated halftoning algorithms have evolved which are mostly based on the concept of fixed-level thresholding and error-diffusion. An elaborate halftoning process called Multiple Error Correction Computation Algorithm (MECCA) was recently published [*]. The most powerful feature of this algorithm is its space- variant dot-size correction mechanism which allows to compensate printer specific technology limitations and, at correct parameter setting, has the effect of linearizing the digital reproduction process.
