Abstract:
A recording head has two or more first nozzle rows from which an ink droplet of a first color is discharged, two or more second nozzle rows from which an ink droplet of a second color is discharged, and two or more third nozzle rows from which an ink droplet of a third color is discharged. In a plurality of nozzle rows from which an ink droplet is discharged on the same line along the relative movement direction, a distance between the first nozzle row and the second nozzle row in the relative movement direction is fixed, and a plurality of distances are present regarding a distance between the first nozzle row and the third nozzle row in the relative movement direction. Concerning an amount-of-ink upper limit that is an upper limit of an amount of ink that is dischargeable per unit area of the print substrate, first printing in which an amount-of-ink upper limit for a combination of the first nozzle row and the third nozzle row is smaller than an amount-of-ink upper limit for a combination of the first nozzle row and the second nozzle row is performed.
