Ink jet printing apparatus and printing method
An ink jet printing apparatus and printing method are provided that can, without the addition of a special structure, suppress density imbalance between the print images formed by ink ejected from each of the ejection ports formed on a print head. As for the plurality of ejection ports, one portion of them are established as multiple impact ejection ports that form multiply impacted pixels at which the number of times ink is impacted at the same area is greater than at other pixels of the print area. And, print control is carried out such that more multiply impacted pixels are printed at print areas printed using ejection ports at the ends of the print head than at print areas printed without using ejection ports at the ends of the print head.
