Abstract:
1. An inkjet printing apparatus having a printing unit provided with a first nozzle array and a second nozzle array in which nozzles are arranged, the first nozzle array and the second nozzle array are arranged along a direction intersecting an arrangement direction of the nozzles so that nozzles in an end part of the first nozzle array and nozzles in an end part of the second nozzle array form an overlapping portion, the apparatus comprising: an acquisition unit configured to acquire information which indicates whether a registration adjustment between the first nozzle array and the second nozzle array which form the overlapping portion was performed; a determination unit configured to determine a distribution rate of print data corresponding to the overlapping portion for each of the first nozzle array and the second nozzle array based on the information; and a distribution unit configured to distribute the print data corresponding to the overlapping portion to the nozzles of the overlapping portion, respectively, based on the determined distribution rate, wherein the determination unit, if the information indicates that the registration adjustment has been performed, determines the distribution rate so that the print data may be distributed to both end parts of the first and second nozzle arrays, and if the information indicates that the registration adjustment has not been performed, determines the distribution rate so that the print data may be distributed to one of the end parts of the first and second nozzle arrays.
