Abstract:
1. A liquid ejecting apparatus comprising: a liquid ejecting head having a nozzle row in which a plurality of nozzles ejecting a liquid on an ejecting target medium is arranged; a moving unit which relatively moves the liquid ejecting head with respect to the ejecting target medium in a main scanning direction intersecting an arrangement direction of the nozzles; and a control unit which permits the liquid ejecting head to eject the liquid so as to form a plurality of test patterns on the ejecting target medium, a nozzle row having a first nozzle group wherein nozzle sets formed by adjacent N (where N is a natural number) nozzles in the nozzle group line up at an interval of N nozzles, and a second nozzle group, where the other nozzles sets of the second nozzle group line up, the test pattern being formed such that a first dot group and a second dot group line up at an interval larger than a reference interval M in a main scanning direction, wherein the first dot group having a plurality of dots where dots are formed from the nozzles of the first nozzle group, the second dot group having a plurality of dots where dots are formed from the nozzles of the second nozzle group, and the plurality of dots lining up at the reference interval M in the main scanning direction.
