Generation of cockling is suppressed to enable superior image quality printing. An inkjet printing device is provided with a head discharging ultraviolet curing ink onto a medium, pinning irradiation sections irradiating the ultraviolet curing ink on the medium with light, and a curing irradiation section arranged on a downstream side of the pinning irradiation sections in a conveying direction of the medium, and radiating light with a shorter wavelength than the pinning irradiation sections.
