Rotated halftone screen geometry that avoids beat-based banding

摘要

Disclosed are methods and apparatus for reproducing an image using one or more halftone screens for one or more respective colorants in the methods and apparatus reducing the beating of one or more excitation frequencies with one or more harmonic frequencies associated with the halftone screens. According to an exemplary method, one or more halftone screens are selected such that the fundamental frequency of an excitation frequency coincides with a harmonic frequency of a halftone screen.
