Claim 1:
2. The printing apparatus according to claim 1,
wherein the second nozzles in the first nozzle row include: a plurality of one-side second nozzles forming a group adjacently on one side in the width direction to the group of the first nozzles in the first nozzle row; and a plurality of other-side second nozzles forming a group adjacently on the other side in the width direction to the group of the first nozzles in the first nozzle row,
the second nozzles in the second nozzle row include: a plurality of one-side second nozzles forming a group adjacently on one side in the width direction to the group of the first nozzles in the second nozzle row; and a plurality of other-side second nozzles forming a group adjacently on the other side in the width direction to the group of the first nozzles in the second nozzle row,
the correction-pattern image includes:
a first dot pattern image including the first dot and the second dot;
a one-side second dot pattern image including:
a one-side third dot corresponding to one of the one-side second nozzles in the first nozzle row; and
a one-side fourth dot corresponding to one of the one-side second nozzles in the second nozzle row; and

an other-side second dot pattern image including:
an other-side third dot corresponding to one of the other-side second nozzles in the first nozzle row; and
an other-side fourth dot corresponding to one of the other-side second nozzles in the second nozzle row,

in the one-side second dot pattern image, the one-side third dot is positioned downstream in the conveying direction from the one-side fourth dot,
in the other-side second dot pattern image, the other-side third dot is positioned upstream in the conveying direction from the other-side fourth dot, and
the first positional shift amount in the first dot pattern image is smaller than a one-side second positional shift amount in the conveying direction between the one-side third dot and the one-side fourth dot in the one-side second dot pattern image, and
the first positional shift amount in the first dot pattern image is smaller than an other-side second positional shift amount in the conveying direction between the other-side third dot and the other-side fourth dot in the other-side second dot pattern image.
