CONTROL OF INK EJECTION AMOUNT BASED ON DOT FORMATION ORDER

摘要

PROBLEM TO BE SOLVED: To provide technology for suppressing image quality deterioration caused by aggregation or bleed of ink. SOLUTION: This printer is provided with a dot data generating part for performing a halftone process with a dither matrix on image data to thereby determine a state of dot formation at each of print pixels of a print image that is to be formed on the printing medium, and generating dot data that represents the determined state of dot formation; and a print image generating part for generating a print image by mutually combining dot groups that are formed at each of a plurality of pixel groups being assumed to have different physical conditions with respect to the dot formation in a common print region. The dither matrix stores each threshold value such that a number of dots to be allocated to each of the plurality of dot groups is determined according to a dot formation order of each of the plurality of dot groups in the common print region in the halftone process.
