ABSTRACT:
A method and apparatus for representing polychromatic half-tone images employs the formation of image spots of equal size. The image spots each contain different colored image points, also of equal size, whose number determines the respective degree of coverage of one primary color. The raster positions at which the image points can be printed within the image spots are disposed in such a manner that each raster point has the same spacing from six adjacent raster points. The sequence by which the raster points are occupied in the image spots during the process of an increasing degree of coverage is fixed such that upon increasing degrees of coverage of all of the primary colors, the image points are first represented next to one another and are only printed on top of one another after the occupation of all raster positions.
