Patent ID: 7954923

Claim:
A liquid ejecting apparatus comprising: a printing head that ejects liquid from a plurality of nozzles to form dots on a recording medium; a head driving section that performs a main scanning for moving the printing head in a main scanning direction; a transporting section that performs a sub-scanning for transporting the recording medium in a sub-scanning direction crossing the main scanning direction; an image forming section that forms an image on the recording medium by repeatedly performing the main scanning of the printing head and the sub-scanning of the recording medium, and forms a first dot formation area by ejecting the liquid from the nozzles during a first main scanning and a second dot formation area adjacent to the first dot formation area by ejecting the liquid from the nozzles during a second main scanning performed after the first main scanning; an overlap control section that performs overlap control for intermittently forming dots on a lower end portion of the first dot formation area and intermittently forming dots on an upper end portion of the second dot formation area so as to make the upper end portion of the second dot formation area overlap with the lower end portion of the first dot formation area and fill spaces between the dots intermittently formed on the lower end portion of the first dot formation area, by controlling the image forming section; an acquiring section that acquires image data; and a cancellation section that cancel the overlap control when a blank area not having any dot in the whole range of a plurality of successive main scanning lines exists in an image represented by the image data and a nozzle forming at least one of the lower end portion of the first dot formation area and the upper end portion of the second dot formation area is positioned at a boundary portion between the blank area and an image forming area having the dots formed thereon.
