A method for determining a recording timing, comprising: a recording step for recording on a medium a plurality of patches disposed along a second axis intersecting with a first axis with a recording head including a first nozzle group, a third nozzle group, and a second nozzle group arranged in order along the first axis; and a timing determination step for determining a recording timing of the recording head based on a patch selected from the plurality of patches recorded on the medium, the recording timing being a timing at which ink is discharged from nozzles of the recording head to perform recording; wherein the plurality of patches each include an overlap region, which is an area of the medium that is recorded on by either or both of the first nozzle group and the second nozzle group, and a first region (Fd) and a second region (Sd), which are areas of the medium that are recorded on by the third nozzle group; the recording is performed so that A ≥ B is satisfied, where A is a width along the second axis of the first region and the second region, and B is a width along the second axis of the overlap region; the recording is performed so that the widths B of the overlap regions of the plurality of patches decrease from patch to patch moving outwards along the second axis in either direction from the center of the plurality of patches; the recording step includes a first recording in which the recording head moves in a first direction along the second axis and the overlap region is recorded with the first nozzle group and the first region is recorded with the third nozzle group, and a second recording in which the recording head moves in a second direction along the second axis and the overlap region is recorded with the second nozzle group and the second region is recorded with the third nozzle group; the timing determination step includes selecting one of the patches in which the position of the first region (Fd) and the position of the second region (Sd) are aligned, and selecting an adjustment value for the recording timing corresponding to the selected patch in order to determine the recording timing; and the position of the first nozzle group along the first axis in the first recording overlaps with the position of the second nozzle group along the first axis in the second recording. a recording step for recording on a medium a plurality of patches disposed along a second axis intersecting with a first axis with a recording head including a first nozzle group, a third nozzle group, and a second nozzle group arranged in order along the first axis; and a timing determination step for determining a recording timing of the recording head based on a patch selected from the plurality of patches recorded on the medium, the recording timing being a timing at which ink is discharged from nozzles of the recording head to perform recording; wherein the plurality of patches each include an overlap region, which is an area of the medium that is recorded on by either or both of the first nozzle group and the second nozzle group, and a first region (Fd) and a second region (Sd), which are areas of the medium that are recorded on by the third nozzle group; the recording is performed so that A ≥ B is satisfied, where A is a width along the second axis of the first region and the second region, and B is a width along the second axis of the overlap region; the recording is performed so that the widths B of the overlap regions of the plurality of patches decrease from patch to patch moving outwards along the second axis in either direction from the center of the plurality of patches; the recording step includes a first recording in which the recording head moves in a first direction along the second axis and the overlap region is recorded with the first nozzle group and the first region is recorded with the third nozzle group, and a second recording in which the recording head moves in a second direction along the second axis and the overlap region is recorded with the second nozzle group and the second region is recorded with the third nozzle group; the timing determination step includes selecting one of the patches in which the position of the first region (Fd) and the position of the second region (Sd) are aligned, and selecting an adjustment value for the recording timing corresponding to the selected patch in order to determine the recording timing; and the position of the first nozzle group along the first axis in the first recording overlaps with the position of the second nozzle group along the first axis in the second recording.
