Printing apparatus and printing method

摘要

A printing apparatus is provided with a transport mechanism section that transports work, a printing mechanism section that has multiple nozzle groups, which perform printing by discharging an ink onto the work as liquid droplets, and control section that controls the actions of the transport mechanism section and the printing mechanism section. In addition, the printing mechanism section includes a first nozzle row that forms a first printing region, a second nozzle row that forms a second printing region, and an overlapping section in which the first nozzle row and the second nozzle row overlap. Further, the control section prohibits overlapping of the first printing region with the second printing region on the work when forming the third printing region.

1. A printing apparatus comprising:
a transport section that transports a recording medium in a transport direction; a printing section configured to move in a perpendicular direction that is perpendicular to the transport direction, the printing section including multiple nozzles which perform printing by discharging an ink, as liquid droplets, onto the recording medium transported by the transport section; and a control section that controls the actions of the transport section and the printing section, the printing section including a first nozzle row, a second nozzle row, and an overlapping section, the first nozzle row being disposed so that each nozzle extends in the transport direction, and forming a first printing pattern on the recording medium, the second nozzle row being disposed so that each nozzle is arranged along the first nozzle row, and forming a second printing pattern on the recording medium, the overlapping section corresponding to a portion in which the first nozzle row and the second nozzle row partially overlap when viewed from the perpendicular direction, while the control section controls the transport section and the printing section, a length along the transport direction of a printing region of the recording medium being longer than a length along the transport direction of the overlapping section, the printing region being formed by the discharging of the droplets from the nozzles in the overlapping section, and the control section controlling the printing section so as to prohibit overlapping of the first printing pattern with the second printing pattern in the printing region of the recording medium.
