    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.
