Abstract

A foil transfer method of performing foil transfer onto a surface of a transfer subject includes preparing a foil transfer tool including a light output portion, preparing the transfer subject and a transfer foil, stacking the transfer foil and a light absorbing film with optical absorptivity on a surface, of the transfer subject, on which the foil transfer is to be performed, to produce a stack body, and while moving either one of the stack body and the foil transfer tool with respect to the other, putting the foil transfer tool into contact with a surface of the stack body at which the light absorbing film is provided and outputting light from the light output portion.

First claim

What is claimed is:

1. A foil transfer method for performing foil transfer onto a surface of a transfer subject, the foil transfer method comprising:
preparing a foil transfer tool including a light output portion;
preparing the transfer subject and a transfer foil;
preparing a light absorbing film with optical absorptivity, the light absorbing film being prepared separately from the transfer foil;
stacking the transfer foil and the light absorbing film on a surface, of the transfer subject, on which the foil transfer is to be performed, to produce a stack body;
preparing a foil transfer device provided with the foil transfer tool and a controller configured or programmed to control the foil transfer tool; and
while moving either one of the stack body and the foil transfer tool with respect to the other of the stack body and the foil transfer tool, putting the foil transfer tool into contact with a surface of the stack body at which the light absorbing film is provided and outputting light from the light output portion, wherein
the foil transfer tool is mounted on a carriage engaged with a guide rail extending in a first direction and configured to move in the first direction by the controller.

2. The foil transfer method according to claim 1 , wherein the transfer foil is a multi-color foil.

3. The foil transfer method according to claim 2 , wherein the multi-color foil is a hologram foil.

4. The foil transfer method according to claim 1 , wherein the light output from the light output portion of the foil transfer tool and the light absorbing film have a complementary color relationship with each other.

5. The foil transfer method according to claim 1 , wherein:
the light absorbing film includes a colored light absorbing layer and a transparent protective film stacked on each other in a stacking direction; and
a surface of the light absorbing film at which the light absorbing layer is provided is located to face the transfer foil to produce the stack body.

6. The foil transfer method according to claim 5 , wherein the light absorbing layer is thinner than the protective film in the stacking direction.

7. The foil transfer method according to claim 1 , wherein the foil transfer tool is capable of pressing the stack body with a first pressing force and a second pressing force larger than the first pressing force.

8. The foil transfer method according to claim 1 , further comprising determining, before producing the stack body, whether or not the transfer foil has optical absorptivity and whether or not the transfer foil is of a single color; wherein
in a case that the transfer foil does not have optical absorptivity or is not of a single color, the transfer foil and the light absorbing film are stacked on the surface of the transfer subject, on which the foil transfer is to be performed.

9. The foil transfer method according to claim 1 , wherein producing the stack body comprises placing the light absorbing film on the surface of the transfer foil.

10. The foil transfer method according to claim 1 , wherein the foil transfer tool includes a solenoid controlled by the controller, and is configured to move in an up-down direction.

11. The foil transfer method according to claim 1 , wherein the transfer foil does not have optical absorptivity.

12. The foil transfer method according to claim 1 , wherein the light absorbing film is a single color film.

13. A foil transfer method for performing foil transfer onto a surface of a transfer subject, the foil transfer method comprising:
preparing a foil transfer tool including a light output portion;
preparing the transfer subject and a transfer foil;
preparing a light absorbing film with optical absorptivity, the light absorbing film being prepared separately from the transfer foil;
stacking the transfer foil and the light absorbing film on a surface, of the transfer subject, on which the foil transfer is to be performed, to produce a stack body;
preparing a foil transfer device provided with the foil transfer tool and a controller configured or programmed to control the foil transfer tool; and
while moving either one of the stack body and the foil transfer tool with respect to the other of the stack body and the foil transfer tool, putting the foil transfer tool into contact with a surface of the stack body at which the light absorbing film is provided and outputting light from the light output portion, wherein
the foil transfer tool includes a solenoid controlled by the controller and is configured to move in an up-down direction.
