  • Patent number: 10200568
    Abstract: Described herein are systems and methods for processing an image such as a halftone image. For example, in some embodiments, pixels of an image are checked to see if when printed would be represented by a given output. Pixels of the image that match defined values are replaced with pixels that are represented by a different set of outputs. This latter set of outputs may be selected to optimize one or more imaging attributes.

  • Patent number: 10183486
    Abstract: When printing on the same printing object with multiple print nozzles in the past, consideration was not given to cases in which the time relationships of the set times and times-to-be-printed become mismatched between the respective print items of the print nozzles. To solve this problem, an inkjet printer that prints on a conveyed printing object and has multiple print nozzles, multiple auxiliary control units for controlling the printing performed by the multiple print nozzles, and a common main control unit connected to the multiple auxiliary control units via communication unit is provided. The main control unit extracts the time relationship of the set times and the time relationship of the times-to-be-printed between the items to be printed by the respective print nozzles of the multiple print nozzles and revises the print data so as to preserve the time relationship of the set times.

  • Patent number: 10183496
    Abstract: Printing methods and systems are described herein. In one example, a method includes rasterizing a document to create color rasters and linearizing the color rasters to create high drop weight (HDW) planes and low drop weight (LDW) planes. HDW and LDW halftone planes are created from the HDW and LDW planes. The HDW and LDW halftone planes are masked to create HDW and LDW printhead maps, and the HDW and LDW printhead maps are merged into print data. The print data is sent to a number of printheads.
