  • 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: 10112379
    Abstract: A three-dimensional part and associated support structure is constructed using an electrophotography-based additive manufacturing system. A support layer is developed using a first electrophotography engine, and a part layer is developed using a second electrophotography engine. The developed support and part layers are transferred to a transfer medium and moved into alignment with a tile region of a layer transfusion assembly, where the transferred part and support layers are transfused to previously-printed layers. This process is repeated for a plurality tile regions and for a plurality of layers to construct a three-dimensional part having a footprint larger than a maximum printable area of the first and second electrophotography engines.

  • 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. The printing system is then used to print the subsequent portion of the print job using the adjusted printing parameters.

  • Patent number: 10059821
    Abstract: A method is used to provide an electrically-conductive polyaniline pattern by providing a uniform layer of a photocurable composition on a substrate. The photocurable composition comprises a water-soluble reactive polymer comprising (a) greater than 40 mol % of recurring units comprising sulfonic acid or sulfonate groups, and (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition. The photocurable composition is exposed to cause crosslinking via [2+2] photocycloaddition of the (b) recurring units, thereby forming a crosslinked polymer. Any remaining water-soluble reactive polymer is removed. The crosslinked polymer is contacted with an aniline reactive composition having aniline monomer and up to 0.5 molar of an aniline oxidizing agent, thereby forming an electrically-conductive polyaniline disposed either within, on top of, or both within and on top of, the crosslinked polymer.

  • Patent number: 10062017
    Abstract: A print engine is adapted to print image data from a plurality of pre-processing systems that supply image data at different image resolutions and halftoning states. A data interface receives the image data and associated metadata including an image resolution parameter and a halftone state parameter. A metadata interpreter interprets the metadata and determines image processing operations that are required to prepare the image data for printing using a printer module. A resolution modification processor module processes the image data to modify its resolution if the metadata interpreter determines that the image resolution of the image data does not match the printer resolution. A halftone processor module processes the image data by applying a halftoning operation if the metadata interpreter determines that the image data is not in an appropriate halftoning state.
