The conventional color halftoning method for laser printer is based on periodic clustered-dot halftoning screen, which visible moire and rosette artifacts may appear. In this paper, the first two color aperiodic, clustered-dot halftoning algorithms, NPAC-MS-MP-CLU-DBS and PARAWACS-MS-MP-CLU-DBS, are introduced, which have the inherent stability during the printing process to resist misregistration and the potential to avoid moire and rosette for the aperiodic property. Besides, the color management pipeline for halftoning algorithms based on NPAC (Neugebauer Primaries area coverages) also be introduced in this paper.
