ABSTRACT:
A method including performing correction of an ink ejection amount for a certain area based on a correction value for a first type row region, and performing correction of an ink ejection amount for another area. The certain area includes a plurality of the first type row regions adjacent to each other in a transport direction. The other area is located on the upstream side in the transport direction from the certain area, and includes a plurality of second type row regions and a plurality of the first type row regions in the transport direction. The second type row region is a region in which a dot row is formed in the movement direction by performing the movement-and-ejection operation another predetermined number of times that is more than the predetermined number of times. A ratio of the second type row regions increases as the distance from the certain area increases.
