  • Publication number: 20070046923
    Abstract: A medium is carried to a predetermined position in a carrying direction. A first pattern is formed on the medium with nozzles on the carrying direction upstream side of a nozzle row constituted by a plurality of nozzles lined up at predetermined intervals. After forming the first pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row. Along with forming on the medium a second pattern that forms a boundary with the first pattern with nozzles on the carrying direction downstream side of the nozzle row, a third pattern is formed on the medium with the nozzles on the carrying direction upstream side of the nozzle row.

  • Patent number: 7168786
    Abstract: A plurality of nozzles forms the first row of nozzles, the second row of nozzles, the third row of nozzles and the fourth row of nozzles, which extend in parallel with a sub scanning direction. A black ink is adapted to be supplied to one row of nozzles. Color inks are adapted to be supplied to the other rows of nozzles, the color inks being different for each of the other rows of nozzles. Positions of the second row of nozzles to the fourth row of nozzles are shifted by ? or ? of an arrangement pitch of the nozzles, in the sub scanning direction, for each of the rows of nozzles, with respect to positions of the first row of nozzles. In a high-speed black mode, the color inks are ejected from corresponding nozzles, in connection with ink ejection of the black ink from corresponding nozzles.
