Abstract:
A printing apparatus includes a printer with printing elements that print dots and a controller that acquires input image data. The controller acquires a pre-correction printing density that is based on test pattern data, which includes a uniform array of pixels, and printing characteristics of printing positions of the dots printed by the plurality of printing elements. The controller calculates a target density by averaging the pre-correction printing density and offsets the target density so that the target density is equal to or greater than the pre-correction printing density. The controller calculates a correction gain of the plurality of printing elements on the basis of the ratio of the target density to the pre-correction printing density and controls the printer on the basis of the correction gain and the input image data.
