Method and apparatus for forming a full-color image

摘要

A full-color image printing method and apparatus operate to form mono-color toned images of individual color components using multiple, e.g., four, mono-color imaging units provided in correspondence to the color components and single-lined screen processors provided in correspondence to the imaging units, and overlap the mono-color toned images sequentially to produce a full-color image on a sheet of print paper. The screen angle is made different among the mono-color toned images and the line pitch of the screen is made virtually equal for all mono-color toned images with the intention of retaining a high-grade color quality and preventing the degradation of picture quality such as a degraded tone quality.
