Abstract

Examination of information contained in a raster image is proposed so as to improve the output print quality obtained from a xerographic or other type marking engine. Raster image information may be local, global, or a combination thereof. The examination will determine whether fine line, large area coverage or half-tone printing should be optimized. Once the image content is determined, marking engine exposure, spot size, or other process related control points may be adjusted in accordance with the sensed image type. The proposal enables both the reproduction of fine lines and heavy black images with the same marking engine.
