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： Each of four areas of 2×2 in one pixel has four sub areas and the four sub areas correspond to four nozzle arrays A to D. In the sub area of each area, information showing what nozzle array is used for a print of the area is defined. The sub area filled in black shows performing therein a print of a dot using nozzles in the nozzle array corresponding to the sub area. In this way, the dot arrangement pattern has information showing the nozzle array to which nozzles used for printing an area belong, for each area. Therefore, without executing the particular data allocation processing such as mask processing, the allocation of the dot data to the plurality of nozzle arrays can be carried out with a simple arrangement.

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.
