Abstract
Even if colors are printed in the same order for each band, time difference unevenness is suppressed which results from a difference in duration from the end of the first scan until the beginning of the second scan. An ink jet printing apparatus completely prints a scan area with a width corresponding to a predetermined length of a nozzle line. The ink jet printing apparatus includes conveying means for moving the print medium, generation means for generating print data in such a manner that in the two scans for completely printing the scan area with the width corresponding to the predetermined length, a print duty for the first scan is higher than a print duty for the second scan, and print control means for carrying out the first scan in an identical direction for all the scan areas completely printed by the two scans.
