A method and information processing system for generating digital images by means of a laser printer (10) on an image carrier (7) is characterised by the fact that for the purpose of creating grey tone in the picture elements (4a to 4e), built up by pixels (5), of an image in each case one or several lines or bars (6, 6a, 6b, 8, 8a, 8b, 9, 9a, 9b, 9c, 11) are generated, the lines or bars extend in parallel with the direction of transportation (Y) of the image carrier (7), the bars or lines of all picture elements are flush with one another in the direction of transportation (Y) of the image carrier (7), the lines or bars have in the direction of printing lines of the laser printer (10) a total width which corresponds to the grey value of the picture element, and that the total width of the lines or bars is changed in steps which correspond to a fraction of the pixel width. The lines or bars of picture elements which are adjacent in the direction of transportation (Y) can also adjoin one another. <IMAGE> |
