ABSTRACT:
This invention relates to a method and apparatus for processing images having color combinations. Such combinations may be embodied in, for example, a black object being printed within a color object or in a black object that includes drops of process color within the object. In these circumstances, undesired image artifacts and halos are eliminated in images that include black portions that are adjacent color portions, and/or improved printed edges are created, by offsetting the corresponding black pixels relative to the color pixels and etching preselected pixels from the image before printing.
