An ink jet printing method is provided, in which "color banding" and "time different unevenness" are solved simultaneously, and bidirectional multi-pass printing can be achieved with a small number of multi-passes. Thus, part of a plurality of groups, which are formed by dividing a nozzle row of a print head with the number of multi-passes, is set to be in a nonuse state (or low allowable rate of printing) in a predetermined scanning direction so as to perform printing, while a mask pattern to be used in a forward scan and a backward scan is suitably changed. Therefore, it becomes possible to unify the orders of providing inks (the orders of printing), and the print timings at a plurality of print scans, between contiguous print regions, and even all over the print regions. |
