  • Patent number: 10291822
    Abstract: Certain methods of generating a color mapping are described. In one method, an output of a color halftone processing pipeline is processed so as to determine a set of Neugebauer Primary area coverage (NPac) values that are representative of the output of the color halftone processing pipeline. These NPac values are then used, together with knowledge of an original input image, to generating the color mapping.

  • Patent number: 10005291
    Abstract: When sub-images are sequentially transferred and connected together to form a larger image than would be possible with a single transfer operation, the occurrence of a color change in the overlapping region of the sub-images is suppressed and the width of the overlapping region is reduced as much as possible. Color image data are divided into image data of two sub-images containing an overlapping region and having edges that coincide for each color ink transferred to paper. Color values of the color image data in the overlapping region are converted by using a color conversion factor group created in advance for each position on the overlapping region so as to cancel out a color change that occurs in the overlapping region when the sub-images are transferred with one overlapping the other. The image data of the sub-images are corrected by adjusting converted color values in the overlapping region by using a correction factor for print density at each position on the overlapping region.

    Abstract: A liquid droplet jetting apparatus includes: a carriage configured to scan in a main scanning direction; a jetting head installed in the carriage, having nozzles arranged in a sub scanning direction intersecting with the main scanning direction, and configured to jet liquid droplets from the nozzles; a conveyer configured to convey the recording medium in the sub scanning direction; and a controller configured to control the carriage, the jetting head and the conveyer. The nozzles form nozzle groups including two nozzle groups adjacent in the sub scanning direction; and the controller is configured to execute a predetermined printing mode in which a pass printing and conveyance of the recording medium in the sub scanning direction are alternately performed. The pass printing causes the carriage to move one time in the main scanning direction while jetting the liquid droplets from the nozzles.
