Abstract
A method of printing a highlight color image uses half-tone printing reference patterns for generating printing values for a print original image for a standard color and for generating printing values for a print original image for a highlight color. The information pertaining to the color values of the original image that are assigned to a standard color region or to a highlight color region is integrated into the half-tone printing reference patterns, whereby the printing of a highlight image is limited to a selection of the corresponding half-tone printing reference pattern and the acceptance of the printing value indicated in the half-tone printing reference pattern. Only one corresponding selection for determining the printing values for the standard color and for the highlight color is carried out for each image point.
