Provided is an inkjet recording device and an inkjet recording method that can selectively perform a high-speed recording mode or a high-quality recording mode without requiring a process of changing configurations of nozzle rows. The head control section performs the discharge control by using all the nozzles belonging to the nozzle groups of respective colors as the usable range Ru in the case where the “high-speed mode” is designated by the mode designating section. On the other hand, in the case where the “high-quality mode” is designated, the head control section determines, for each color, the usable range Ru being a part of the nozzle range Rn configured by the nozzle groups, and performs the discharge control using only the nozzles belonging to the usable ranges Ru so as to cause the ink droplets to be discharged according to the particular color order at any positions on the recording medium. |

1. An inkjet recording device, comprising:
a recording unit that is reciprocally movable along a main-scanning direction relative to a recording medium, and the recording unit includes a plurality of nozzles for discharging ink droplets; a moving mechanism that moves the recording unit and the recording medium relatively in a sub-scanning direction that is a direction intersecting the main-scanning direction; a head control section that performs a discharge control of the recording unit while the moving mechanism relatively moves the recording unit and the recording medium; and a mode designating section that designates one of a plurality of recording modes different from the discharge control, and the plurality of recording modes including a first recording mode and a second recording mode, wherein when a set of two or more nozzles that are arranged along the sub-scanning direction and discharge ink droplets of a same color is defined as one nozzle group, the recording unit including at least two nozzle groups that discharge ink droplets of at least two colors, in a case where the first recording mode is designated by the mode designating section, the head control section performs the discharge control by using all of the nozzles belonging to the nozzle group of each color as a usable range, and in a case where the second recording mode is designated by the mode designating section, the head control section determines, for each color, a usable range being a part of a nozzle range configured by the nozzle group, and performs the discharge control by using only the nozzles belonging to the usable range, so that ink droplets are discharged at any positions on the recording medium according to a particular color order. |
