  • Patent number: 8210627
    Abstract: A print head which includes at least two discharge nozzle lines arranged on at least two lines, out of a base line corresponding to a radial direction of the rotating print object and at least one offset lines parallel to the base line, discharges ink drops of the same color from discharge nozzles of the discharge nozzle lines, moves the print head so as to minutely move the discharge nozzle lines on the base line or the offset lines, and discharges ink drops of the same color from the discharge nozzles passing through second paths moved minutely from the first paths over the rotating print object. In this way, the ink drops are discharged on the area where print defects are caused because the area is not on the paths of the discharge nozzles before the discharge nozzles are minutely moved.

  • Patent number: 8061792
    Abstract: A printing apparatus includes a printing unit for printing visual information on a non-recording surface of a rotatably driven recording medium by discharging ink droplets. A control unit controls movement of the printing unit in a radial direction of the recording medium, and discharge timing of the ink droplets. The printing unit prints the visual information by multi-path printing by printing on a same radius position of the non-recording surface by discharging ink from different ink discharge nozzles. The control unit controls the printing unit so as to print with a first printing pattern having a first number of paths and a second printing pattern having a second number of paths. The first printing pattern is used on other locations of the non-recording surface and the second printing pattern is used when printing on an innermost periphery region of the non-recording surface.
