FLEXOGRAPHIC PRINTING PLATE INCLUDING PSEUDO-RANDOM PATTERN OF RAISED FEATURES

A flexographic printing system prints image patterns including one or more uniform image regions on a substrate. A flexographic printing plate includes a pattern of raised features for transferring ink to the substrate in accordance with the image pattern. An anilox roller having a plurality of anilox cells is configured to transfer ink to the flexographic printing plate. Uniform image regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised feature shapes positioned in a pattern of pseudo-random feature locations. An average spacing between the raised feature shapes in the uniform image regions is less than an anilox cell size such that a plurality of the raised feature shapes receive ink from a single anilox cell of the anilox roller.

PRINTING SYSTEMS INCLUDING A RIGID PRINTING PATTERN AND AN INKING ROLL HAVING AN ELASTICALLY DEFORMABLE SURFACE

A printing system is provided. The printing system (300) includes a printing roll (310) having a rigid printing pattern (312) on a surface thereof configured to receive an ink material (330); and an inking roll (320) positioned adjacent to the printing roll. The inking roll includes an elastically deformable surface and a number of cells (324) disposed on the elastically deformable surface. A method of printing is also provided. The method includes (a) inking at least a portion of a rigid printing pattern (312) on a surface of a printing roll (310) by contacting the rigid printing pattern with an inking roll (320); and (b) contacting the rigid printing pattern with a substrate (350), transferring the ink material from the rigid printing pattern to a surface of the substrate. Printing systems and methods can achieve higher printing feature resolutions than typically achievable via flexographic printing.

MANUFACTURING LIGHT FIELD PRINTS

Techniques for manufacturing a light field print using a printing press. The techniques include: identifying at least one characteristic of the printing press at least in part by printing at least one calibration pattern; obtaining content to be rendered using the light field print, the content comprising multiple scene views; generating, based at least in part on the content and the at least one characteristic of the printing press, a front target pattern and a back target pattern; and using the printing press to: print the front target pattern on a first side of a substrate; and print the back target pattern on a second side of the substrate.
