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： This invention reduces an unprinted stripe occurred by edge deviation of a printhead. An inkjet printing apparatus according to this invention can execute a first printing mode in which an image is printed by scanning the printhead in a first region on the printing medium N times and scanning the printhead in a second region adjacent to the first region (N+1) times, and a second mode in which an image is printed by scanning the printhead in the first region M times and scanning the printhead in the second region (M+1) times. The width, in the conveyance direction of the printing medium, of the second region printed in the second printing mode is narrower than the width, in the conveyance direction of the printing medium, of the second region printed in the first printing mode.

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： To achieve high-quality printing by controlling an ink-travelling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink is landed on a desired position of the printing medium effectively without disturbing the ink ejection, independent of a difference in the thickness of the printing medium. An electric field between a printing head and the printing medium is generated by applying a voltage to a platen of conductive material positioned immediately below the printing medium. At this point, the voltage applied to the platen is adjusted so that the electric field of a preferable intensity can be generated on a face of the printing head where ejection openings are formed irrespective of the thickness of the printing medium.

摘要： To achieve high-quality printing by controlling an ink-traveling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink ejected to areas outside edges of the printing medium is prevented from being attracted to the end portions in margin-less printing. This configuration includes: a platen, made of a conductive material, positioned immediately below the printing medium; an absorber positioned at a side of the edge; and a mesh conductive member disposed on the absorber. A first voltage is applied to the platen, causing polarization in the printing medium, and a second voltage higher than the first voltage is applied to the conductive member. Thereby, ink ejected outside the edges in the margin-less printing, travels straight-forwardly toward the conductive member without being attracted to the end portions, and is absorbed into the absorber via the conductive member.
