  • Patent number: 10293620
    Abstract: An inkjet printing apparatus uses a printing head including a plurality of nozzle arrays each including a plurality of nozzles arrayed in a first direction, the nozzle arrays being arranged in a second direction. A compensating unit compensates for an ejection failure of a defective nozzle by causing a compensating nozzle to eject ink to a predetermined pixel area in a case where the print data corresponding to the defective nozzle indicates ink ejection to the predetermined pixel area. The compensating unit determines the compensating nozzle such that the compensating nozzle satisfies both a first condition that the compensating nozzle is not a defective nozzle and a second condition that the print data indicates that nozzles belonging to the nozzle array including the compensating nozzle do not eject ink to a pixel area corresponding to N pixels (N is a positive integer) around the predetermined pixel area in the first direction.
