Abstract:
1. A printing apparatus comprising: a first yellow nozzle group in which a plurality of nozzles ejecting a yellow ink are arranged in a predetermined direction; a second yellow nozzle group in which a plurality of nozzles ejecting a yellow ink are arranged in the predetermined direction and which is disposed to be offset from the first yellow nozzle group in the predetermined direction; a first magenta nozzle group in which a plurality of nozzles ejecting a magenta ink are arranged in the predetermined direction; a second magenta nozzle group in which a plurality of nozzles ejecting a magenta ink are arranged in the predetermined direction and which is disposed to be offset from the first magenta nozzle group in the predetermined direction; a first cyan nozzle group in which a plurality of nozzles ejecting a cyan ink are arranged in the predetermined direction; a second cyan nozzle group in which a plurality of nozzles ejecting a cyan ink are arranged in the predetermined direction and which is disposed to be offset from the first cyan nozzle group in the predetermined direction; and a control unit that controls to eject the inks from the nozzles while relatively moving the nozzle groups and a medium in a direction crossing the predetermined direction, and to print an image on the medium, wherein a position of an area of printing overlap of the first yellow nozzle group and the second yellow nozzle group in the predetermined direction is offset from a position of area of the printing overlap of the first magenta nozzle group and the second magenta nozzle group in the predetermined position and a position of an area of printing overlap of the first cyan nozzle group and the second cyan nozzle group in the predetermined position, and wherein the position of the area of printing overlap of the first magenta nozzle group and the second magenta nozzle group in the predetermined position is the same as the position of the area of printing overlap of the first cyan nozzle group and the second cyan nozzle group in the predetermined direction.
