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： In an inkjet printing apparatus, a printing medium is conveyed in a conveying direction by causing the printing medium to adsorb to the surface of the endless belt by electrostatic force. When printing, the surface potential of the printing medium directly below the printing head is acquired. The discharge speed of the ink that has been associated in advance with the acquired surface potential is obtained, and an amount of variation in the landing position of the ink is determined based on the scanning speed of the printing head, the distance from the printing head to the printing medium, and the discharge speed of the ink. The timing of discharge of ink from the printing head is corrected to cancel out the determined amount of variation, and printing is performed based on image data in accordance with the corrected timing.
