Abstract
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.
Claims5
A decorative printing method for forming a printing film on a surface to be printed of a printing target formed by a base material, the method comprising ejecting droplets of ink having the same color as the color of the decorative printing film from nozzles of an inkjet printer onto the surface to be printed to form the printing film, in which a non-flat surface portion forms at least a portion of the surface to be printed, wherein:
- the distance from each nozzle to the surface to be printed is represented by X (mm) and the amount of ink of each droplet is represented by Y (pl);
- the droplet amount Y is represented by the equation:
- Y=0.9X1.5;
- and
- when the maximum value of the distance X (mm) is greater than 5 mm, droplets each having an amount greater than the droplet amount Y are ejected from each nozzle.
