Abstract: A recording device, including a transport roller whose circumference length is different from nozzle array length in a transport direction, performs TP recording control to record a group of test patterns, in which a plurality of test patterns including a first patch and a second patch with different positions in the transport direction are arranged in a main scanning direction, and in which an amount of liquid ejected for a boundary area between the first patch and the second patch is different for each test pattern, wherein, in the TP recording control, records a first TP group and a second TP group at different positions in the transport direction onto a medium, transports the medium by a first distance based on the nozzle array length as a transport between the recording of the first patch and the second patch of the TP, and, as a transport between the recording of the second patch of the first TP group and the recording of the first patch of the second TP group, transports the medium by a second distance

Abstract: A recording device, when n is an integer of 3 or more, controls a recording head to record n test patters from which a shift amount is acquirable between a scan and a scan different from each other on a medium in a main scanning direction, at least three test pattern is formed by a plurality of patches recorded by a plurality of scans, the n test patterns are formed so as to be different from each other in positional relationship of the plurality of patches and recorded side by side in the main scanning direction in an order different from an order in which the positional relationship of the plurality of patches gradually changes.
