<p>A main scan pass which relatively moves a recording head and a recording medium in a main scan direction and forms dots on the recording medium, and a sub-scan which relatively moves the recording medium and the recording head in a sub-scan direction that intersects with the main scan direction, are performed, and thereby multi-pass recording which completes forming of the dots on a main scan line by N (N is an integer equal to or greater than 2) times of the main scan passes is performed. A dot rate which represents a rate of pixels in which dot recording is performed in each main scan pass of the multi-pass recording is set so as to be changed gradually and periodically over a plurality of sections in the main scan direction. The number of values of the dot rates different from each other in the plurality of sections lined up in the main scan direction is set so as to be equal to or greater than 3.</p> |
