Dot Recording Apparatus, Dot Recording Method, Computer Program Therefor, and Method of Manufacturing Recording Medium

摘要

A dot recording apparatus performs multi-pass recording through which recording of dots is terminated in main scanning passes of N times (N is an integer equal to or greater than two) on a main scanning line, the multi-pass recording is performed for respective supercell regions defined as a region including pixel positions on which recording of dots is performed in each main pass, a first supercell region recorded in a first pass in the supercell regions is configured with a first concave polygon having a concave portion and a convex portion, a second supercell region recorded in a second pass in the supercell regions is configured with a second concave polygon having a concave portion and a convex portion, and shapes of the first concave polygon and the second concave polygon are inversely symmetrical shapes in the main scanning direction.

1. A dot recording apparatus comprising:
a recording head including a plurality of nozzles; a main scanning driving mechanism that performs 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 intersected with the main scanning direction; and a controller that controls the recording head, the main scanning driving mechanism, and the sub-scanning driving mechanism, wherein the controller performs multi-pass recording through which recording of dots is terminated in main scanning passes of N times (N is an integer equal to or greater than two) on a main scanning line, wherein the multi-pass recording is performed for respective supercell regions defined as a region including pixel positions on which recording of dots is performed in each main pass, wherein a first supercell region recorded in a first pass in the supercell regions is configured with a first concave polygon having a concave portion and a convex portion, wherein a second supercell region recorded in a second pass in the supercell regions is configured with a second concave polygon having a concave portion and a convex portion, and wherein shapes of the first concave polygon and the second concave polygon are inversely symmetrical shapes in the main scanning direction.
