Claim One:
1. A printing device comprising: (A) a transporting section that transports a medium in a transporting direction; (B) an upstream side background color nozzle row in which nozzles that eject background color ink to the medium are lined up along the transporting direction; (C) an upstream side color nozzle row that is an upstream side color nozzle row where nozzles that eject colored ink to the medium are lined up along the transporting direction, and where respective nozzles of the upstream side color nozzle row overlap respective nozzles of the upstream side background color nozzle row in the transporting direction; (D) a downstream side background color nozzle row that is a downstream side background color nozzle row provided further in the downstream side of the upstream side background color nozzle row in the transporting direction, and where nozzles that eject the background color ink to the medium are lined up along the transporting direction; (E) a downstream side color nozzle row that is a downstream side color nozzle row where nozzles that eject colored ink to the medium are lined up along the transporting direction, and where respective nozzles of the downstream side color nozzle row overlap respective nozzles of the downstream side background color nozzle row in the transporting direction; (F) a moving section that simultaneously moves the upstream side background color nozzle row and the upstream side color nozzle row in either an outward direction or a returning direction from among intersecting directions that intersect the transporting direction, and simultaneously moves the downstream side background color nozzle row and the downstream side color nozzle row in either the outward direction or the returning direction; and (G) a controlling section that makes the upstream side background color nozzle row and the upstream side color nozzle row form a background image, and makes at least the downstream color nozzle row form a color image, wherein the upstream side background color nozzle row and the upstream side color nozzle row are made to eject the respective inks thereof to tone the background image in the simultaneous movement of the upstream side background color nozzle row and the upstream side color nozzle row in either the outward direction or the returning direction when the background image is formed.
