  • Patent number: 6697171
    Abstract: A process for adjusting the content of a digitized image file used in printing an interlaced image on a lenticular lens material to substantially eliminate ghosting effects which might otherwise occur when the printed image is viewed by an observer. A pixel address within the image file is selected, as is a preselected number of pixel addresses adjacent the selected address on both sides thereof. Percent color values contained at each of the addresses within the resulting range of addresses are added together and the result divided by the total number of addresses to compute an average color percent value. The percent color value at the selected address is compared with the computed average and is changed by a predetermined amount if the percent color value is greater or less than the computed average. The revised percent color value is then stored at the selected address. The process is repeated for each pixel address within the file.

  • Patent number: 6091482
    Abstract: A lenticular preprinting process producing a composite image which, when printed, is assembled with a lenticular lens material (18). The composite image is developed from a plurality of images (A-D) which include both graphic and textual images. Each of the respective images are digitized and a pixel array for the image is formed. Separate digital files are created for each image. Next, computerized files are separately created for continuous tone images and for linework images. From these computerized files, separate raster image files for the continuous tone and linework images are produced. Next, segments from each raster image file is combined in a predetermined sequence with segments from the other raster image files to separately interlace the respective continuous tone and line work images. The resulting combined files are now linked to produce an image having both continuous tone and linework constituents.
