Abstract
A liquid ejecting apparatus includes a plurality of nozzles; a moving portion which moves the plurality of nozzles to the medium; and a control portion which controls the plurality of nozzles and the moving portion. The plurality of nozzles include a first-type nozzle group which records dots using a nozzle use rate which is less than a first threshold value; a second-type nozzle group which records dots using a nozzle use rate which is the first threshold value or more, and less than a second threshold value; and a third-type nozzle group which records dots using a nozzle use rate of the second threshold value or more. The control portion executes multipass recording in which recording of dots is completed using main scanning passes of N times, ejects the liquid in order of ejecting of the first-type nozzle group and the third-type nozzle group with respect to a first region, ejects the liquid using the second-type nozzle group with respect to a second region which is close to the first region, and ejects the liquid in order of ejecting of the third-type nozzle group and the first-type nozzle group with respect to a third region which is close to the second region, but is not close to the first region.
