  • Publication number: 20220247888
    Abstract: A system and method enable determining a total colorant limit for printing images. The system includes memory which stores instructions for: determining a grain value for each of a set of printed patches printed on a first print media, the grain value being based upon a visual contrast sensitivity function computed for the respective patch, the set of printed patches including patches printed on the print media at different total colorant values; determining a total colorant limit for the first print media, as a function of the total colorant values and corresponding grain values for the printed patches in the set, wherein the total colorant limit is a total colorant value which corresponds to a grain value which does not exceed a threshold grain value for the first print media. A processor executes the instructions.

  • Patent number: 9233568
    Abstract: Methods and systems print test patterns in different test pattern areas on print media using a printer to produce a printed item. The printer has a printing width in a cross-process direction, and each of the test pattern areas is in a different cross-process location of the printing width. The test pattern areas are distributed across the entire printing width, and each of the test pattern areas partially overlaps at least one other test pattern area in the cross-process direction. Next, these methods and systems individually scan the sections of the printed item using a scanner that has a scanning width that is less than the printing width. This produces individual scans of the test pattern areas. The widths of the test pattern areas are equal to or less than the scanning width. Then, these methods and systems can calibrate cross-process characteristics of the printer based on the scans.

  • Patent number: 8540357
    Abstract: An imaging device includes a media supply and handling system configured to move media along a path. A printing system is disposed along the path that includes at least one printhead for applying melted phase-change ink of at least one color to the media to form images thereon. A fixing assembly is disposed along the path downstream of the printing system that is configured to apply heat and/or pressure to the melted phase change ink of the images on the media. A coating system is disposed along the path downstream from the spreader. The coating system includes at least one printhead for applying a clear ink on top of the images formed on the media by the printing station.

  • Patent number: 7857442
    Abstract: A folding system includes a media pathway configured to transport a print substrate having phase change ink thereon. The folding system includes a folding apparatus disposed along the media pathway configured to fold the print substrate. A folding heater is configured to heat the phase change ink on the print media to a folding temperature. The folding temperature is above ambient temperature and below a melting temperature for phase change ink.

  • Publication number: 20100086339
    Abstract: A system cuts media printed with phase change ink in a manner that reduces the ink debris produced by cutting solidified ink. The system includes a heater configured to heat phase change ink on the media moving through the heater to a temperature at which the ink is malleable, the temperature being above room temperature and below a temperature at which phase change ink melts, and a cutter configured to receive the media after the media has been heated by the heater and to cut the media. The blade of the cutter may also be heated to facilitate media cutting with a reduced likelihood of solid ink debris being generated.

  • Patent number: 4764805
    Abstract: A preview still video image, comprising a smaller number of binary bits to expedite digital transmission, is constructed block-by-block from a full-quality still video image by (a) sampling every n video pixels in each horizontal video line of each block and averaging between adjacent ones of the sampled pixels, and (b) sampling every m horizontal video lines in each block and averaging between adjacent ones of the sampled lines. An image is reconstructed from the preview image by using a buffer which temporarily stores the last video line in each block, and interpolating it with the first line in the next block, as well as interpolating all subsequent adjacent line pairs in the block. Adjacent pairs of the sampled pixels in each line are also interpolated. The image thus reconstructed comprises as many pixels and horizontal lines as the full-quality image.
