Abstract

One common artifact in color printing is the moiré caused by the superposition of the different color separations. This problem is well known and a common approach to minimize the moiré 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-separation moiré in order to allow for a better trade-off in the halftone design.
