Information processing apparatus, information processing method, and storage medium

An information processing method for controlling a printing apparatus including a printing head in which a plurality of nozzle arrays having a plurality of nozzles that eject ink being aligned in a predetermined direction are arranged, so as to perform printing of each pixel with each nozzle set, which includes one nozzle each from each nozzle array, the information processing method comprising:

• obtaining digital halftone data which is configured with a plurality of pixels each of which holds a pixel value indicative of the number of printing dots to be formed with ink that is ejected from nozzles;
• setting a plurality of nozzle groups that evenly divide the plurality of nozzles included in each nozzle set and allocating one of the plurality of nozzle groups to each pixel of the digital halftone data so that appearance frequencies of the respective nozzle groups are approximately even;
• and
• selecting the number of nozzles corresponding to a pixel value of a pixel from among a plurality of nozzles that are set as one of the nozzle groups allocated to the pixel out of a plurality of nozzles included in the nozzle set corresponding to each pixel of the digital halftone data, so that disparity in the number of times of selection is reduced, and outputting a signal indicative of the selected nozzles in association with the pixel.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute an information processing method for controlling a printing apparatus including a printing head in which a plurality of nozzle arrays having a plurality of nozzles that eject ink being aligned in a predetermined direction are arranged, so as to perform printing of each pixel with each nozzle set, which includes one nozzle each from each nozzle array, the information processing method comprising:

• obtaining digital halftone data which is configured with a plurality of pixels each of which holds a pixel value indicative of the number of printing dots to be formed with ink that is ejected from nozzles;
• setting a plurality of nozzle groups that evenly divide the plurality of nozzles included in each nozzle set and allocating one of the plurality of nozzle groups to each pixel of the digital halftone data so that appearance frequencies of the respective nozzle groups are approximately even;
