摘要： A large and small dot distribution pattern is generated, for each chip, according to a large and small dot distribution ratio and ejection failure nozzle information. In doing so, a bias of large and small dot distribution ratio at a nozzle position including an ejection failure nozzle is set to be smaller than that at a nozzle position that does not including an ejection failure nozzle. Then, dot data to be printed by the ejection failure nozzle is equally distributed to large dot nozzles that can eject normally and small dot nozzles. By such a configuration, even if a plurality of printing chips have different printing characteristics, ejection failure compensation processing is performed to minimize image degradation caused by an unexpected ejection failure and an average ejection volume of each of the chips converge on a fixed target ejection volume, which leads to reduction of density unevenness among the chips.

摘要： Provided are an inkjet printing apparatus and inkjet printing method that can, regardless of an ejection frequency of a print head, stabilize density of an image expressed on a print medium. For this purpose, an ink concentration integrated value is obtained according to the ejection history of each nozzle so as to be increased by data indicating non-ejection of the nozzle or decreased by data indicating ejection. Then, image data on the target pixel is corrected such that density of the target pixel is further reduced as the pixel is subjected to printing by a nozzle having a higher ink concentration integrated value.

摘要： A necessary amount of suppression ink is applied to each portion of an ink absorber in a short time and in an efficient manner. For that end, carriage scan is performed while changing an ejection condition of suppression ink so as to change an application amount of suppression ink according to a position of an ink absorber. This makes it possible to appropriately apply suppression ink, which suppresses accumulation of ink, to the entire area of the ink absorber by carriage scan in a short time even if an application amount of accumulation ink differs from part to part of the ink absorber.
