发明名称 INKJET PRINTER AND INKJET PRINTING METHOD
摘要 PROBLEM TO BE SOLVED: To enhance the abrasion resistance of a color image on a printing medium, and security while reducing a manufacturing cost of an inkjet printer apparatus. SOLUTION: In a discharge part 3 of the inkjet printer 1 including discharge mechanisms 31a to 31d to discharge fine liquid droplets of color inks and a discharge mechanism 32 to discharge fine liquid droplets of transparent inks, the color image is drawn in a color image printing region on a printing medium 9 by the discharge mechanisms 31a to 31d. Furthermore, by the discharge mechanism 32, the color image on the printing medium 9 is covered with the transparent ink and also an encryption image is drawn in a blank region around the color image printing region. In the inkjet printer 1, the covering of the color image and the drawing of the encryption image are carried out by the same transparent ink to be discharged from one discharge mechanism 32. Thus, the enhancement of the abrasion resistance of the color image and security can be achieved while reducing a manufacturing cost of the apparatus of the inkjet printer 1.
