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： 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.

摘要： An object of this invention is to provide a printing apparatus capable of reducing slanting displacement for high-quality image. To achieve this object, slant information of a printing element array (141, 142, 143, 144) in a printhead scanning direction is obtained. Image data used to print by one scanning of the printhead (11) is stored in a printing buffer (204). Image data of three columns used by the printing element array are stored in a transfer buffer (213). Image data of two successive columns out of the image data of three columns are read out from the transfer buffer (213), and image data of a column is selected based on the slant information. Image data of one column is newly read out from the printing buffer (204), and the data area of the transfer buffer corresponding to one column is rewritten. The selected image data is transferred to the printhead (11) for printing.
