  • Patent number: 10234763
    Abstract: An article is prepared with surface regions having different contact angles. A reactive silane material is attached to a surface having a reactive tail component that is contacted with a first corresponding reactant, followed by imagewise UV exposure to cause imagewise reaction of the reactive tail component and first corresponding reactant, forming reacted regions and latent reaction regions. After rinsing, a second corresponding reactant that is capable of reaction with the reactive moiety is applied. Uniform UV exposure leads to a second reaction product only in the latent reaction regions. After rinsing, first regions comprise exclusively the first reaction product and second regions comprising exclusively the second reaction product. These first and second regions have contact angles that differ by 10-110 degrees. A composition can be applied that is exclusively attracted to either the first regions or the second regions, but not to both the first and second regions.

  • Patent number: 10192150
    Abstract: A print engine includes a printer module for printing image data in a plurality of different print modes, wherein each print mode has an associated line print time. A data interface receives image data and associated metadata for a print job from a pre-processing system, the metadata including print mode metadata. A digital memory stores a plurality of pulse timing functions, each pulse timing function corresponding to one of the line print times associated with the plurality of print modes. A metadata interpreter interprets the metadata and determines the print mode to be used to print the image data. A printer module controller controls the printer module to print the image data using the pulse timing function corresponding to the line print time associated with the print mode, wherein each light source is activated for a pulse count corresponding to a pixel code value of an associated image pixel.

  • Patent number: 10150319
    Abstract: A method for forming a flexographic plate for an image pattern including image features. The image pattern includes an array of image pixels, wherein the image pixels include printing pixels corresponding to portions of the image pattern where ink is to be printed on a substrate by the flexographic plate. Edge regions and interior regions of the image features are identified, which are separated by gap regions. A fine texture pattern is applied to the edge regions and a coarse texture pattern is applied to the interior regions to form a textured image pattern which is used to form the flexographic plate. No texture pattern is applied to the gap regions thereby leaving gaps between the edge regions and the interior regions of the image features.

  • Patent number: 10126696
    Abstract: A method is described for calibrating a linear printhead including an array of light sources. A test target is printed by activating the light sources in the printhead in accordance with digital image data for the test target, wherein a current value for each light source is controlled responsive to an initial set of current control parameters. A digital image capture system is used to capture an image of the printed test target, and the captured digital image is analyzed to determine an estimated exposure gain error for each light source. An updated set of current control parameters is then determined which is adapted to compensate for the estimated exposure gain errors.

  • Patent number: 10115134
    Abstract: A method for printing a print job including a plurality of document pages includes receiving a target cost for printing the print job. The printing system is used to print a portion of the print job including one or more document pages using an initial set of printing parameters. An estimated total cost for printing the print job is determined including an actual cost determined for printing the portion of the print job and an estimated cost for printing a remainder of the print job. A data processing system is used to automatically determine adjusted printing parameters to be used for printing a subsequent portion of the print job if the estimated total cost exceeds the target cost.
