ABSTRACT:
A correction-pattern forming method, for example, for forming a correction pattern with which it is possible to precisely correct discrepancies between dot formation positions in the moving direction is achieved. A correction-pattern forming method for forming a correction pattern on a medium, comprises: a step of moving a nozzle row in which a plurality of nozzles for ejecting a liquid to form dots on a medium are arranged in a row; and a step of forming a correction pattern that has a difference in darkness in a moving direction of the nozzle row and that is for correcting a discrepancy between dot formation positions in the moving direction by causing at least two nozzles, among the plurality of nozzles, in the nozzle row to eject the liquid at a different timing for each nozzle.
