Patent number: 8333457Abstract: The present invention is used for a printing target having a non-flat surface portion in at least a portion of a printing surface. To form a decorative printing film on the printing surface of a base material, ink droplets of the same color as the color of the printing film are ejected from nozzles of an inkjet printer onto the printing surface. The distance from the nozzles to the printing surface is represented by X (mm). The droplet amount of the ink is represented by Y (pl). When the maximum value of the distance X is greater than 5 mm, the droplets are ejected from the nozzles each by an amount greater than the droplet amount Y represented by the equation: Y=0.9X1.5.Type: GrantFiled: February 9, 2011Date of Patent: December 18, 2012Assignee: Toyoda Gosei Co., Ltd.Inventors: Yosuke Maruoka, Takashi Sekiya, Daiichiro Kawashima
