To provide an inkjet method that improves glossiness of a cured coating film when radiation curable ink compositions are applied in an overlapping manner and an inkjet recorder.SOLUTION: An inkjet method records a radiation curable ink composition comprising a polymerizable compound. The radiation curable ink composition comprises a first ink composition and a second ink composition, and the inkjet method comprises a first ejection step for ejecting the first inkjet composition by an inkjet head 3 and causing it to adhere to a recording medium 2, a first curing step for irradiating the first ink jet composition adhered to the recording medium 2 with radiation, a cooling step for cooling the recording medium 2, a second ejection step for ejecting a second inkjet composition by the inkjet head 3 to the cooled recording medium 2 and causing it to adhere to at least a portion of a region to which the first ink composition adheres and a second curing step for irradiating the second ink composition adhered to the recording medium 2 with radiation.SELECTED DRAWING: Figure 2 【課題】放射線硬化型のインク組成物を重ね塗りした際に、硬化塗膜の光沢感が向上するインクジェット方法およびインクジェット記録装置を提供すること。【解決手段】インクジェット方法は、重合性化合物を含む放射線硬化型インク組成物を記録するインクジェット方法であって、放射線硬化型インク組成物は、第１インク組成物と、第２インク組成物と、を含み、インクジェット方法は、第１インクジェット組成物をインクジェットヘッド３で吐出して記録媒体２に付着させる第１吐出工程と、記録媒体２に付着した第１インクジェット組成物に対して、放射線を照射する第１硬化工程と、記録媒体２を冷却する冷却工程と、冷却された記録媒体２に、第２インクジェット組成物をインクジェットヘッド３で吐出して、第１インク組成物が付着した領域の少なくとも一部に付着させる第２吐出工程と、記録媒体２に付着した第２インク組成物に対して、放射線を照射する第２硬化工程と、を備える。【選択図】図２
