    摘要: This invention relates to an ink jet recording apparatus and a recording method for recording images of high density with the amount of ink placed per unit area on a recording medium being kept constant even if the resolvability when recording is changed. When the amount of ink of an ink droplet discharged from a recording head is constant (25 pl), the average number of recorded dots conforming to the resolvability is found on the basis thereof, and the number of recordable dots is found from this average number of dots. The difference between this number of actually recorded dots and the average number of recorded dots is adjusted by reducing the value of recording data in advance.

    摘要: A region to be covered by a cover plate (208) on an ejection opening forming surface (205) of an ink-jet head or an ink-jet head to which the cover plate (208) is installed are determined, on a basis of content of a rebounding mist generated upon ejection of an ink and a processing liquid in overlaying fashion. By this, in the ink-jet printing apparatus performing printing by ejecting the ink and the processing liquid for making the ink insoluble, deposition of the insoluble substance contained in the rebounding mist generated upon ejection of an ink and a processing liquid in overlaying fashion can be successfully prevented.

    摘要: A method and an apparatus for ink jet printing use a print head including a first nozzle group for discharging a first ink, a second nozzle group for discharging a second ink and a third nozzle group for discharging a printability improving solution. The third nozzle group is displaced between the first nozzle group and the second nozzle group. The first nozzle group discharges the first ink on the printing medium based on image data to form an image, the third nozzle group discharges the printability improving solution on the image formed on the printing medium by means of another step, and the second nozzle group discharges the second ink on the image formed on the printing medium. The printability improving solution has higher penetrability into the printing medium compared to the ink.
    The method and apparatus can attain a clear colored, high density image without color mixing, which has high water resistance on plain paper, with a low running cost.
