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, which is a difference between an integer multiple of the circumference length and two times the first distance.
