    Abstract: For a multi-pass printing, an image of a unit area is printed by M printing scans of M print regions of first and second nozzle arrays. Each of N pieces of column data is printed by a different printing scan. Ejection data for the first nozzle array is generated using a first mask pattern and ejection data for the second nozzle array is generated using a second mask pattern different from the first mask pattern, for each of the N pieces of column data. On that basis, the first mask pattern and the second mask pattern have a complementary relationship in each of the M print regions. Further, in each of the first mask pattern and the second mask pattern, a combination of print regions, of the M print regions, for printing dots at the same position on the print medium has a mutually complementary relationship.

    Abstract: There are provided a printing system, a method of generating a halftone processing rule, a method of acquiring a characteristic parameter, image processing device and method, a halftone processing rule, a halftone image, a method of manufacturing a printed material, an ink jet printing system, and a program which are capable of reducing an operation load of a user and acquiring a halftone processing rule appropriate for the printing system. A characteristic parameter acquisition chart (100) including a pattern for acquiring characteristic parameters related to characteristics of the printing system is output, and the output characteristic parameter acquisition chart (100) is read by image reading means. The characteristic parameters are acquired by analyzing the read image of the characteristic parameter acquisition chart (100), and halftone processing rules that define the processing contents of halftone processes used in the printing system are generated based on the acquired characteristic parameters.

  • Patent number: 10556419
    Abstract: A method for operating a three-dimensional object printer compensates for inoperative ejectors. The method identifies image data values associated with an inoperative ejector that stored in a memory with other image data values for a three-dimensional object to be printed by the three-dimensional object printer. The method replaces the image data values associated with the inoperative ejector with image data values associated with an operative ejector that correspond to a material that is different than a material ejected by the inoperative ejector and operates a plurality of ejectors with reference to the other image data values and the replaced image data values to enable the operative ejector to eject drops of the material that is different than the material ejected by the inoperative ejector into the three-dimensional object at positions where the inoperative ejector would have ejected material.

  • Patent number: 10434765
    Abstract: A specifying section specifies in printing data a first dot position at which a defective nozzle discharges an ink droplet to print the ink droplet on a medium when the defective nozzle is not defective, but is normal, and specifies in printing data a second dot position different from the first dot position based on priority information in which priority is set for each pixel. A data correcting section corrects the printing data. The collecting corresponds to allocating an amount of ink of the first dot position to the second dot position. When the first dot position at which the ink droplet is provided to the medium if the defective nozzle is not defective is specified, a neighboring second dot position different from the first dot position is specified based on the preset priority information, and the data correcting section corrects the printing data so as to allocate the amount of ink to the second dot position based on the mount of ink of the first dot position.

  • Patent number: 10427403
    Abstract: Regarding an image forming apparatus for printing an input image and including a print head having a head sensor configured to sense information from the input image printed on a print medium, there is a method of determining a head sensor position parameter in the image forming apparatus. The method includes printing a first swath of the input image on the print medium and determining the head sensor position parameter by performing a sub-method. The sub-method includes capturing, via the head sensor, a target image from the printed first swath, comparing the target image to a reference image for the first swath based upon the input image, and determining the head sensor position parameter based on a relative shift between the target image and the reference image.
