<p>PROBLEM TO BE SOLVED: To improve the visibility and the decoration of a printing part with a small amount of pigment and to improve the adhesion of a part to be printed by constituting the printing part through the use of printing ink containing inorganic, metallic and/or luminous pigment on the part to be printed, which is made a rough surface. SOLUTION: A first display part 7 is provided at one corner part on the front surface side of a cartridge main body. The display of a maker, the display of the name of a product, the display of a manufacturing number and decoration, etc., are print-formed at the part to be printed, which is made the rough surface 18, at the first display part 7 by using the printing ink 19 containing inorganic, metallic and/or luminous pigment. The surface 18 is formed to make an area larger than a printing area to which the ink 19 is to be stuck and the grain size at the surface 18 is larger than that of the pigment of the ink 19. Therefore, the surface of the first display part 7 is magnified to improve visibility and to reduce pigment to improve the adhesion of the ink 19 with this.</p> |
