PROBLEM TO BE SOLVED: To print improved black by eliminating image artifacts and halos upon printing black mingled with or in the color part of the image. SOLUTION: The combination may be composed of a black object to be printed in a color object, or a black object including drops of process color. In this situation, black pixels are offset against corresponding color pixels, and the preselected pixels are etched from the image before printing. As a result, undesirable image artifacts and halos are eliminated and/ or improved print edge portions are produced in an image including a black part adjacent to a color.
