Abstract
A method for suppressing phantom images in a digital copying or printing process wherein toner material in the form of pixels of image information (D (x,y), in which D is the image density for point x,y, is transferred through a sequence of process steps from a photoconductive surface to an image-recording medium, where at least one process step is influenced in a predetermined manner by at least one preceding process step for the same surface point x,y, which comprises connecting the image information for each pixel of image information to be printed on the basis of image information D(x,y-&Dgr;y1) for at least the pixel associated with the same surface point x,y, and said preceding process step, thereby compensating for the influence of said preceding process step.
