Abstract
An ejection part (3) in an inkjet printer (1) has ejection mechanisms (31a to 31d) for ejecting fine droplets of colored ink and an ejection mechanism (32) for ejecting fine droplets of clear ink, and a colored image is formed on a colored image print area of print medium (9) by the ejection mechanisms (31a to 31d). By the ejection mechanism (32), the colored image on the print medium (9) is coated with the clear ink and a code image is formed on a blank area around the colored image print area. In the inkjet printer (1), since the coating of the colored image and the forming of the code image are performed with the same clear ink ejected from the one ejection mechanism (32), improvement of wear resistance and improvement of security of the colored image can be achieved while reducing manufacturing cost of the apparatus of the inkjet printer (1).
