Abstract: The aim is to form a print pattern remarkably glossy and quick-dry for efficient cure of inks. An inkjet printing device is provided that includes a controller. The controller prompts a UVLED unit to emit ultraviolet light to precure inks of an ink set discharged from an inkjet head unit by irradiating the inks with ultraviolet light. The controller further prompts the UVLED unit to irradiate the precured inks with ultraviolet light. The ink set includes color UV inks each containing an ultraviolet-curable resin and a colorant but containing no metallic particle, and a solvent UV ink containing an ultraviolet-curable resin, a solvent, and metallic particles.
