摘要

One common artifact in color printing is the moire caused by the superposition of the different color separations. This problem is well known and a common approach to minimize the moire is the use of rotated halftone dots of precise frequency and angle for the different separations. In low resolution devices, the precise relationship between the different separations is commonly hard to satisfy and compromises have to be made. This paper describes a method to vary the undercolor removal (UCR) and gray component replacement (GCR) schemes employed as a function of the predicted inter-reparation moire in order to allow for a better trade-of in the halftone design.
