Patent ID: 8882222

Claim:
A liquid jetting apparatus configured to jet a liquid onto a recording medium, comprising: a head unit in which a plurality of nozzles are aligned at an interval in a nozzle-row direction to form a nozzle row; and a controller configured to control a liquid jetting operation of the head unit to jet the liquid, from a part of the plurality of the nozzles belonging to a first range and another part of the plurality of nozzles belonging to the second range, toward the recording medium to form a plurality of dot-rows arranged in a direction of intersection which intersects the nozzle-row direction, wherein each of the dot-rows includes a switching range in which jetting the liquid from the part of the nozzles belonging to the first range and jetting the liquid another part of nozzles belonging to the second range are switched at a plurality of switching positions, wherein the plurality of dot-rows are formed so that: the switching range in which the nozzles in the first range and the nozzles in the second range are switched, becomes narrower than the first range and the second range; the switching positions are set such that, at the time of forming at least a part of the dot-rows in the plurality of dot-rows, there are three or more than three switching positions of the nozzles in the first range and the nozzles in the second range, in the switching range; and the switching range is set such that, the switching range differs for the two dot-rows which are adjacent in the direction of intersection.
