Abstract:
1. An ink-jet printing method of printing on a printing medium by discharging the ink from a printhead constituted by arraying a plurality of printing nozzle arrays each formed by a plurality of printing nozzles for discharging ink, comprising: a generation step of generating printing data to be printed by each of at least first and second adjacent printing nozzle arrays out of the plurality of printing nozzle arrays on the basis of tone information of image data to be printed; and a printing step of printing by discharging ink to a pixel of the printing medium from the first and second printing nozzle arrays on the basis of the printing data generated in the generation step, wherein in the generation step, printing data corresponding to each of the first and second printing nozzle arrays is generated in a range in which a sum of the number of dots to be printed by the first printing nozzle array and the number of dots to be printed by the second printing nozzle array does not exceed a predetermined number, and wherein the predetermined number includes a maximum number of printing dots with which influence of an air flow generated along with ink discharge from the first and second printing nozzle arrays is admissible.
