  • Patent number: 10099474
    Abstract: In a method to check a fixative print head for nozzle failures, a reference mark is printed by the nozzles of a colored ink print head and a test mark is printed via overprinting of the colored ink by the nozzles of the colored ink print head and of a fixative by the nozzles of the fixative print head onto a printing substrate web. The test mark and the reference mark are compared with one another. If the reference mark and the test mark correspond to one another (e.g., at least in part), this indicates that nozzles of the fixative print head are operating incorrectly. If operating incorrectly, the nozzles have, for example, failed entirely or eject the fixative at too great an angular deviation.

  • Patent number: 9884481
    Abstract: A printing apparatus including a head unit 12, a main scan driver 14, and a controller 20 is provided. The head unit 12 includes a first-color nozzle and a second-color nozzle, and performs main scan operations in an outward direction and main scan operations in a homeward direction. During each main scan operation, the controller 20 selects some pixels, as first-color ejection object pixels for which ink drops of a first color should be ejected, from pixels included in an area of a medium 50 which is an object of the corresponding main scan operation, and selects at least some pixels other than the first-color ejection object pixels, as second-color ejection object pixels for which ink drops of a second color should be ejected, from the pixels included in the area of the medium which is the object of the corresponding main scan operation.

  • Patent number: 9868307
    Abstract: A printing apparatus includes a carriage unit, and carries out printing on a recording medium while transporting the recording medium. The carriage unit includes a first head that discharges an ink and a second head that discharges an ink of the same color, and the second head is disposed so as to be adjacent to the first head in an x axis direction, and to overlap with the first head in a y axis direction. In an outgoing path in the reciprocation of the carriage unit, a printing density of a first image, which the first head prints, gradually decreases toward an upstream side in a transport direction of the recording medium, and the first image includes a dot group, in which at least two dots formed using the ink from the first nozzles are linked to one another in the x axis direction. In addition, in a return path in the reciprocation of the carriage unit, the second nozzles print a second image, which supplements a decrease in the printing density of the first image.

  • Patent number: 9849668
    Abstract: Provided are an image processing device, an image processing method, and an ink jet recording apparatus that can prevent the occurrence of density unevenness, such as banding, regardless of a duty, without causing deterioration of image quality. A jetting rate indicating an ink jetting rate of each of a plurality of nozzles which jet ink in a recording head including the nozzles is determined. A nozzle pattern indicating which of the plurality of nozzles of the recording head is used to record each pixel of an image on a recording medium is determined. The jetting rate of the nozzle which records each pixel is reflected in a gradation value of each pixel of the image on the basis of the determination result of the jetting rate and the determination result of the nozzle pattern to convert the gradation value of each pixel.
