  • Patent number: 11948026
    Abstract: Formed is a dither pattern that makes it possible to output an image with excellent dot dispersibility and reduced graininess regardless of controls after quantization processing. To this end, an extended pattern in which multiple divided pixels correspond to each of multiple pixels included in quantization data and one or more of the multiple divided pixels are determined as dot-arrangeable-pixels in which dots can be printed is generated. Thereafter, the thresholds of the dither pattern are set based on the extended pattern in which the dots are arranged to obtain predetermined dispersibility.

  • Publication number: 20240086662
    Abstract: An object is to print a high quality image with resistance to print misalignment. To this end, the image processing apparatus generates quantized data for printing a first dot pattern and a second dot pattern in an overlapping manner. The first dot pattern and the second dot pattern are lattice patterns varying in a combination of two basis vectors. In a combined dot pattern obtained by combining the first and second dot patterns, there is a neighboring dot in which a dot in the first dot pattern and a dot in the second dot pattern are arranged at an interval smaller than a lattice spacing. The neighboring dot includes multiple neighboring dots varying in an approach direction.

  • Patent number: 7560168
    Abstract: A gas barrier laminate film comprising a resin substrate on which a gas barrier vapor deposition layer, and a gas barrier covering layer are laminated, wherein the gas barrier covering layer is formed through the coating, and drying of a coating liquid comprising Si(OR1)4 or the hydrolyzates thereof, (R2Si(OR3)3)n or the hydrolyzates thereof (wherein R1 and R3 are individually CH3, C2H5 or C2H4OCH3, and R2 is an organic functional group) and a water-soluble polymer having a hydroxyl group.
