Patent ID: 8277020

Claim:
A liquid ejection apparatus, comprising: a nozzle row in which a plurality of nozzles that eject liquid toward a medium are arranged in a predetermined direction; a moving mechanism that causes a relative movement between the medium and the nozzle row in an intersecting direction that intersects with the predetermined direction; and a control portion that causes the liquid to be ejected from the nozzle row based on an image data during the relative movement of the medium and the nozzle row in the intersecting direction, wherein the control portion determines: according to image data, whether a pixel is an ejection pixel at which a liquid is to be ejected and a non-ejection pixel at which the liquid is not to be ejected; according to the image data, a nozzle requiring flushing from among the plurality of nozzles; and from among ejection pixels that are adjacent to the at least one non-ejection pixel that is associated with the nozzle requiring flushing, the ejection pixel at which a largest size dot is to be formed, and wherein the control portion causes the nozzle requiring flushing to eject the liquid to the non-ejection pixel adjacent to the ejection pixel at which the largest size dot is to be formed and that is associated with the nozzle requiring flushing.
