Abstract
The screen printing process together with halftoning techniques for reproducing continuous tone color images has given considerable moire problems. Interferences between the halftoning technique and the screens, and the subsequent screens may be alleviated by appropriate orientation of the screens with respect to each other. Preferentially a frequency modulation halftoning technique is used for halftoning the color components.
