Abstract: Provided is a printing device including: nozzles which discharge a first aqueous ink for printing a main image; nozzles which discharge a second aqueous ink for printing a background image; and a control unit which controls printing of an image on a medium having an aqueous ink absorption property based on one selected from a first mode for printing the main image using the first aqueous ink and a second mode for superposing and printing the main image using the first aqueous ink and the background image using the second aqueous ink, wherein the amount of first aqueous ink dischargeable per unit area of the medium when the main image is printed on the medium in the second mode is less than that when the main image is printed on the medium in the first mode.

Abstract: A printing device that forms a background by a first ink and images on the background by a second ink includes a head having first and second nozzle lines that eject, respectively, the first and second inks. The inks are ejected as the head moves, with respect to a medium, in a main scanning direction intersecting the first and second nozzle lines. A transport section transports the medium in a sub-scanning direction along the first and second nozzle lines. In an ejecting operation, the first and second inks are ejected in the relative movement in the main scanning direction and the relative transportation is performed. In the ejecting operation, more nozzles are used in the second nozzle line than in the first nozzle line, and more ejections are performed from the second nozzle line than from the first nozzle line, thereby filling a predetermined width in the sub-scanning direction.
