发明名称 Ink-jet printing apparatus and ink-jet printing method
摘要 In divided printing method performing printing for the same printing region for a plurality of times of scanning, in order to avoid formation of banding due to density variations at a boundary in each scanning region, a predetermined nozzle width (e.g. four nozzle width) of boundary portion is set for each scanning region corresponding to a nozzle array established by dividing a plurality of nozzles (e.g. 248 nozzles) of a printing head by N (e.g. N=4). The number of times of scanning in the boundary portion is set, e.g. three times, smaller than that in region other than the boundary portion. Also, for mutually adjacent boundary portions, three times of scans of each of the adjacent boundary portions are performed simultaneously. By this, in each of the boundaries of respective scanning regions, no time difference will be caused in scan for printing respective regions.
