There is provided an electromagnetic irradiation device which includes, an irradiator which irradiates droplets which are attached to a recording medium with an electromagnetic wave; an irradiation control unit which causes the irradiator to irradiate with the electromagnetic wave periodically; and a frequency setting unit adapted to set a frequency of an irradiation period which is a period during which the irradiator is caused to emit the electromagnetic wave to be equal to or greater than 5 Hz, and less than 1000 Hz, when there is an instruction of increasing the surface gloss of a printed matter, and to set the frequency of the irradiation period to be less than 5 Hz, or equal to or greater than 1000 Hz, when there is no instruction of increasing the surface gloss of the printed matter or when there was an instruction of decreasing the surface gloss of the printed matter. A corresponding method is also provided. |
