ABSTRACT:
The order of the arrangement of ejection opening arrays of two types of ink overlapping in reciprocating scan is decided as follows. An ejection order is decided so that the case where the fixing areas of a main droplet and a satellite are different (dot area is increased) in the forward and backward scan first occurs. By this configuration, the area of the dot and the portion in which different colors are generated due to the difference in the overlapping order in the reciprocating scan can be reduced, compared with the case where the arrangement order is opposite to the above-described case. As a result, a difference in color between areas for which printing is completed by the reciprocating scanning is reduced and thus color unevenness of a printed image can be reduced.
