PROBLEM TO BE SOLVED: To suppress degradation of an image quality of an ejection image by ejecting other electromagnetic wave curable inks towards pixels on a medium to which one electromagnet wave curable ink is ejected. SOLUTION: The printing device has a plurality of heads which eject mutually different electromagnetic wave curable inks towards the medium, a plurality of irradiation sections respectively corresponding to the plurality of heads for illuminating each of the mutually different electromagnetic wave curable inks ejected by the plurality of heads, and a controller which controls the heads and irradiation sections. A first ejecting operation of ejecting one electromagnetic wave curable ink, a first irradiation operation of illuminating the one electromagnetic wave curable ink with electromagnetic waves, a second ejecting operation of ejecting towards pixels on the medium to which other electromagnetic wave curable inks are ejected to overlap the one electromagnetic wave curable ink, and a second irradiation operation of irradiating electromagnetic waves are executed in this sequence so that a contact angle α2 of other electromagnetic wave curable inks to one electromagnetic wave curable ink becomes larger than 90 degrees.
