Recording device and control method of recording device

A recording device comprising:

• a head configured to discharge an ink of ultraviolet curing type toward a medium;
• an irradiation unit configured to irradiate the medium with an ultraviolet ray;
• a carriage mounted with the head and the irradiation unit;
• a movement mechanism configured to move the carriage relative to the medium;
• and
• a control unit configured to control the movement mechanism and the irradiation unit, wherein
• the movement mechanism executes a forward operation of moving the carriage in a first direction with respect to the medium and a return operation of moving the carriage in a second direction opposite to the first direction with respect to the medium, and
• the control unit
• causes the head to execute discharge of the ink while causing the carriage to move in the forward operation, and causes at least the irradiation unit to execute irradiation while causing the carriage to move in the return operation, and
• makes a moving speed of the carriage in the return operation higher than a moving speed of the carriage in the forward operation.
