1. A recording device comprising:
a recording head that has a nozzle array with a plurality of nozzles for ejecting liquid onto a medium, the nozzles being arranged in a predetermined nozzle alignment direction, and that ejects liquid while moving in a first direction that intersects the nozzle alignment direction to perform recording;
a transport section that has a transport roller configured to rotate to transport the medium and that transports the medium in a second direction that intersects the first direction; and
a control section that controls recording by the recording head and transport by the transport section, wherein
a circumference length of the transport roller is different from a nozzle array length, which is a length of the nozzle array in the second direction,
the control section
performs TP recording control to record, on the medium, 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 second direction are arranged in the first direction and an amount of liquid ejected for a boundary area between the first patch and the second patch is different in the first direction for each test pattern and,
in the TP recording control,
records a first test pattern group and a second test pattern group, which are the test pattern groups, at different positions in the second direction on the 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 test pattern, and
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, as a transport between the recording of the second patch of the first test pattern group and the recording of the first patch of the second test pattern group.
