INKJET PRINTER AND PRINTING METHOD USING SAME

摘要

An inkjet printer capable of adhering UV inks onto a printing medium without mixing them and capable of curing the UV inks when the UV inks have become flat is provided. An inkjet printer (10) includes a guide rail (15b) that opposes a platen (12a) and that extends in a left-right direction; a printing unit including a carriage (21) that can reciprocate freely in the left-right direction along the guide rail (15b), a printer head (22) that discharges the UV ink, and a right ultraviolet radiation device (23R) and a left ultraviolet radiation device (23L) that output ultraviolet radiation; and a controller that controls intensities of the ultraviolet radiations output from the right ultraviolet radiation device (23R) and the left ultraviolet radiation device (23L). The right ultraviolet radiation device (23R) and the left ultraviolet radiation device (23L) are arranged on either side of the printer head (22) in the left-right direction. The controller controls the intensities of the ultraviolet radiations output from the right ultraviolet radiation device (23R) and the left ultraviolet radiation device (23L) depending on a direction of movement of the carriage (21).
