  • Patent number: 10274883
    Abstract: Cross-track spacing variations for a plurality of printer subsystems of an electrophotographic printing system are characterized by printing first and second test pattern and capturing image of the printed test patterns. The first and second test patterns are chosen so that the printed test patterns respond differently to cross-track spacing variations in different printer subsystems. The first and second digitized test patterns are analyzed to determine parameters that characterize an attribute of the printed test pattern as a function of cross-track position. A first defect model is used to determine estimated cross-track spacing variations for one or more printer subsystem as a function of the determined parameters.

  • Patent number: 10246561
    Abstract: A method is used to prepare silver nanoparticle cellulosic polymer composites. A cellulosic polymer, reducible silver ions in an amount of a weight ratio to the cellulosic polymer of 5:1 to 50:1, and an organic solvent are mixed. Each organic solvent has a boiling point at atmospheric pressure of 100° C. to 500° C. The Hansen parameter (?TPolymer) of the cellulosic polymer is less than or equal to the Hansen parameter (?TSolvent) of the organic solvent. The resulting premix solution is heated to at least 75° C., and a (d) nitrogenous base is added to provide a concentration of the nitrogenous base in an equimolar amount or in molar excess in relation to the amount of reducible silver ions, thereby forming a silver nanoparticle cellulosic polymer composite. After cooling, the silver nanoparticle cellulosic polymer composite is isolated and re-dispersed in an organic solvent to provide a non-aqueous silver-containing dispersion.

  • 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: 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.
