Abstract

The objective of the present invention is to further enhance the quality of printing. A printing device 12 is provided with an inkjet head 202 and a control unit 120, wherein the control unit 120: sets, for each nozzle, a nozzle-by-nozzle selection rate, which is the proportion of ejection positions to be ejected onto in one main scanning operation, among ejection positions included per unit length in a main scanning direction line, which is an arrangement of ejection positions lined up in a main scanning direction at intervals corresponding to the printing resolution, and, for a plurality of nozzles in an end portion region, sets nozzle-by-nozzle selection rates that gradually decrease toward the end; and if a nozzle capable of ejecting ink in any one of the main scanning operations to an ejection position included in one main scanning direction line is defined as a line-corresponding nozzle, sets the nozzle-by-nozzle selection rates such that, for at least some of the main scanning direction lines, the sum of the nozzle-by-nozzle selection rates set for the line-corresponding nozzles is a proportion other than 100%.
