  • Patent number: 10179462
    Abstract: Optimization of ink recipes for spot colors in printers. Often, ICC Profiles are optimized for smooth rendering of images; thus, color recipes often contain more inks than are required for matching a color when generated from a Profile. When transitioning from one color to another, it is better to make smaller changes in inkings. This goal is not served when printing spot colors. Spot colors are often single, solid colors that do not vary in gradients from one to another. Herein is a discussion including dividing an N-ink set into subsets, generating an ink recipe for a desired recipe in each ink subset, and selecting a subset based on predetermined criteria. Where a spot color is out of Gamut, that color is mapped to the Gamut.

  • Patent number: 9669633
    Abstract: Ink port adapters for multi-color inkjet heads. In one embodiment, the ink port adapter includes two hose fittings for connecting to hoses, and four openings that align with four ink ports of a four-color inkjet head. The adapter includes one ink path that connects one of the hose fittings to two of the openings, and another ink path that connects the other hose fitting to the other two openings. The adapter therefore converts the four-color inkjet head into a two-color inkjet head.

  • Patent number: 9639791
    Abstract: A multicolor image can include multiple overlaid items including a black region covering a color region. Raster image processing adds the color data to color pixels of the raster data print page uniformly across the area of the raster data print page that corresponds to the color region of the multicolor image, and adds the black data to over-print pixels (where the black region covers the color region in the multicolor image). Such over-print pixels include both the color data and the black data. The color data (but not the black data) is removed from the over-print pixels that are positioned a preset pixel distance from non-black color pixels. The raster data page is output from the processor device to a printing engine, and the printing device prints the raster data page on print media to produce a physically printed reproduction of the multicolor image.

  • Patent number: 9561656
    Abstract: There is provided an ink-jet printer including an ink-jet head, a conveyance section, and a controller. The ink-jet head includes a plurality of nozzle groups. Between the plurality of nozzle groups, the nozzles forming the nozzle groups are positioned in conformity with each other, respectively, in a second direction. The controller causes the conveyance section to convey the recording medium between a first pass and a second pass such that the respective nozzle groups have partly overlapped scanning areas, and causes the ink-jet head to print separately between the first pass and the second pass in the second direction. The controller sets usable bordering positions in the overlapping range with respect to the passes. The controller sets the usable bordering positions based on one of such conditions as a duty of printing on the recording medium and a type of the nozzle groups to be used in printing.

  • Patent number: 9522526
    Abstract: In a printer, an inkjet head includes a plurality of head units. Each head unit has a nozzle layout area in which nozzles are arranged in an alignment direction crossing a conveying direction. The head units are arranged in a first row and a second row in the conveying direction. One head unit in the first row and another head unit in the second row define an overlap length. The overlap length is a length in the alignment direction of an overlap region in which the nozzle layout area of the one head unit and the nozzle layout area of the another head unit partially overlap in the conveying direction. The one head unit is shifted from the another head unit in the alignment direction. The overlap length in a center portion of the inkjet head is larger than that in each end portion of the inkjet head.

  • Patent number: 9469129
    Abstract: Both highly reliable detection of a mark and suppression of a sheet consumption amount can be achieved when a continuous sheet is cut on an image basis after a plurality of images has been printed on the continuous sheet. For this purpose, at the time of a first surface printing operation, by accumulating correction factors obtained for a plurality of pages, a more highly reliable correction factor is obtained. Further, at the time of a second surface printing operation, by controlling a conveyance operation with the highly reliable correction factor, a cut mark is surely detected by the detecting operation of the cut mark sensor within a limited range.
