Abstract
A printing apparatus includes a printing head that has a plurality of nozzle modules corresponding to various ink colors arranged in parallel, an abnormal nozzle specifying unit that specifies an abnormal nozzle that is deviated from an ideal dot printing position by a predetermined distance or more among nozzles constituting each of the nozzle modules of the printing head, and a density correction unit that corrects a density of a dot printing line to be printed by the nozzles including the abnormal nozzle specified by the abnormal nozzle specifying unit and printing the same line as the abnormal nozzle. The density correction unit corrects printing data corresponding to the dot printing line printed by the nozzles including the abnormal nozzle and printing the same line as the abnormal nozzle so as to be close to densities of other dot printing lines to be printed by only normal nozzles.
