Abstract
A control section is included which performs a background image pre-printing which enables each ink to be ejected from the upstream side background color nozzle row and the downstream side color nozzle row and can land the color ink after landing the background color ink on the medium in a region concerning the transport direction, and a background image post-printing which enables each ink to be ejected from the upstream side color nozzle row and the downstream side background color nozzle row and can land the background color ink after landing the color ink on the medium in a region concerning the transport direction, the control section performing the printing so as to switch over the background image pre-printing and the background image post-printing on one medium.
Claims8
A printing apparatus comprising:
- a transport portion that transports a medium in a transport direction;
- an upstream side background color nozzle that ejects a background color ink to the medium;
- an upstream side color nozzle that ejects a color ink to the medium are aligned along the transport direction;
- a downstream side background color nozzle that ejects the background color ink to the medium and is disposed in the downstream side further than the upstream side background color nozzle concerning the transport direction;
- a downstream side color nozzle that ejects the color ink to the medium and is disposed in the downstream side further than the upstream side color nozzle concerning the transport direction;
- a moving section that moves the upstream side background color nozzle, the upstream side color nozzle, the downstream side background color nozzle, and the downstream side color nozzle in an intersection direction intersecting the transport direction;
- and
- a control section that performs:
- a background image pre-printing which enables each ink to be ejected from the upstream side background color nozzle and the downstream side color nozzle and can land the color ink after landing the background color ink on the medium, and
- a background image post-printing which enables each ink to be ejected from the upstream side color nozzle and the downstream side background color nozzle and can land the background color ink after landing the color ink on the medium,
- the control section performing the printing so as to switch over the background image pre-printing and the background image post-printing on the one medium.
A printing method using a printer which includes:
- a transport portion that transports a medium in a transport direction;
- an upstream side background color nozzle that ejects a background color ink to the medium;
- an upstream side color nozzle that ejects a color ink to the medium are aligned along the transport direction;
- a downstream side background color nozzle that ejects the background color ink to the medium and is disposed in the downstream side further than the upstream side background color nozzle concerning the transport direction;
- a downstream side color nozzle that ejects the color ink to the medium and is disposed in the downstream side further than the upstream side color nozzle concerning the transport direction;
- a moving section that moves the upstream side background color nozzle, the upstream side color nozzle, the downstream side background color nozzle, and the downstream side color nozzle in an intersection direction intersecting the transport direction;
- and
- a control section that performs:
- a background image pre-printing which enables each ink to be ejected from the upstream side background color nozzle and the downstream side color nozzle and can land the color ink after landing the background color ink on the medium, and
- a background image post-printing which enables each ink to be ejected from the upstream side color nozzle and the downstream side background color nozzle and can land the background color ink after landing the color ink on the medium, the method comprising:
- discriminating a region where the background image pre-printing and the background image post-printing are performed on the medium;
- printing so as to switch over the background image pre-printing and the background image post-printing based on the discrimination result.
