Claim Text:
1. A dot recording apparatus comprising: a recording head that includes a plurality of nozzles; a main scanning driving mechanism that performs a main scanning pass for forming dots on a recording medium while relatively moving the recording head and the recording medium in a main scanning direction; a sub-scanning driving mechanism that performs sub-scanning for relatively moving the recording medium and the recording head in a sub-scanning direction that intersects the main scanning direction; and a control unit, wherein the control unit performs multi-pass recording in which dot recording on a main scanning line is completed by N main scanning passes (N is a predetermined integer of 2 or greater), wherein in dot recording in each main scanning pass, the dot recording is performed with a super cell region, having a boundary line portion which is not parallel to either the main scanning direction or the sub-scanning direction in at least a portion of a boundary line between the super cell region and another super cell region, as a unit, the super cell region including one or more unit super cells formed as a dot group of one mass by some of the plurality of nozzles, and wherein in the same main scanning pass, the number of unit super cells recorded by m nozzles (m is an integer of 2 or greater) at an end portion of the recording head is smaller than the number of unit super cells recorded by m nozzles at a center portion of the recording head.
