Abstract
When completing an image in a predetermined area by an odd or even number of bidirectional printing scans, this invention makes it possible to suppress lines of image defects and density variations and thereby print a high-quality image at high speed. In completing an image by an odd number of bidirectional printing scans, the print data for small ink droplets and large ink droplets are thinned using the first and second thinning pattern. The first and second thinning pattern thin the print data for small ink droplets and large ink droplets so that a difference between the total print ratio of all forward printing scans of the odd number of scans and the total print ratio of all backward printing scans of the odd number of scans when the first thinning pattern is used differs from that when the second thinning pattern is used.
