  • Generation of halftone overlays for combination with halftoned images
    Patent number: 5715382
    Abstract: The generation of personalised documents, or documents including variable data, may require one or more varying overlay images to be printed on top of a background image. In order to avoid the generation of the background image for each document separately, a method is provided to store the background image permanently and to merge it with the overlay images just before printing. A transparency notion may be introduced to avoid masking of the background image by horizontally oriented rectangular overlays. The overlay image and the background image may be generated by a process of multilevel halftoning, suitable for printing by an electrophotographic printing device, using colored toner.
