  • 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.

  • Patent number: 7942489
    Abstract: Disclosed is a liquid emitting apparatus for emitting a liquid pressurized by a pressure generated by a pressure generating element is emitted as liquid droplets onto a support. A controller (68) controls an emission controller (63) so that the current value of the pulse current supplied to a heating resistor (42a) will have a current value difference within ±10% with respect to the current value of the pulse current supplied to a heating resistor (42b). By so doing, variations in the position of deposition of an ink droplet i emitted with variable emitting directions may be suppressed to enable printing to a high-quality image in which deterioration in the image quality variations ascribable to color time variations or white streaks is prohibited.
