Inkjet printer and printing method

摘要

It is an object to reduce the cost and achieve effective curing of ultraviolet curable ink. An inkjet printer (1) comprises an inkjet head unit (6) having inkjet heads for ejecting UV inks, an UVLED unit (7) having a UVLED for emitting ultraviolet light, and a control unit (8) for controlling the inkjet head unit (6) and the UVLED unit (7). The control unit (8) controls the inkjet head unit (6) and the UVLED unit (7) to move in the scanning direction A, controls the inkjet heads to eject UV inks, and controls the UVLED to emit ultraviolet light of a first light quantity. After that, the control unit (8) controls the inkjet head unit (6) and the UVLED unit (7) to move in the direction opposite to the scanning direction A and controls the UVLED to emit ultraviolet light of a second light quantity.
