Ink-jetting recording apparatus and liquid ejecting apparatus
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 ⅓ or ⅔ 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.
