Abstract:
1. An inkjet printing apparatus comprising: a printing unit configured to print using a printhead having a plurality of nozzles to discharge ink on a printing medium; and a control unit configured to control the printing unit to print in accordance with any one of a plurality of modes including a first printing mode and a second mode, wherein the first printing mode is a mode in which printing is executed so that both a first region which is completed printing by scanning the printhead N times (N is an integer not less than 1) and a second region which is completed printing by scanning the printhead (N+1) times exist, and the second printing mode is a mode in which printing is executed so that both a third region which is completed printing by scanning the printhead M times (M is an integer not less than 2, and M>N) and a fourth region which is completed printing by scanning the printhead (M+1) times exist, wherein the control unit controls the print unit to print so that: the second region printed in the first printing mode is printed by scanning the print head (N+1) times including scanning of 2 times by a group of nozzles having an X number of nozzles (X is an integer not less than 2) which are arranged at two ends of the printhead in a direction which intersects a scanning direction of the printhead, and the fourth region printed in the second printing mode is printed by scanning the print head (M+1) times including scanning of 2 times by a group of nozzles having a Y number of nozzles (Y is an integer not less than 1, and X>Y) which are arranged at two ends of the printhead in the direction which intersects the scanning direction of the printhead.
