Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foil stamping method capable of easily embossing a free-designed surface on a foil to be stamped.

[0002]

2. Description of the Related Art It is known that a letter, a design, and the like are stamped on paper of a pamphlet, a ticket, or the like in order to enhance the decorativeness of various pamphlets, tickets, and the like, and to prevent forgery.

Conventionally, such a foil-pressing operation is performed by placing a foil provided with an adhesive layer on a lower surface on a member to be foil-pressed, such as a paper surface, and forming a foil-pressing plate having a pressing convex surface protruding in the form of characters or designs. By applying pressure while heating the foil, the foil is bonded to the member via the adhesive layer according to characters and patterns.

Further, when the surface of the foil to be stamped is to be smoothed, the foil is pressed using a foil stamping plate having a smooth pressed convex surface. Further, when embossing is performed on the surface of the foil to be pressed, a foil-pressing plate having a convex and concave portion of a required design including characters and patterns formed on a pressing convex surface is used, so that the surface of the foil at the time of pressurizing is formed. Required irregularities are generated.

[0005]

In the above-described conventional foil stamping method, a foil stamping plate must be produced each time the surface design of the foil is changed. There was a problem that it took time and workability was poor.

An object of the present invention is to provide a foil stamping method which can solve such a conventional problem.

[0007]

According to the present invention, a foil-pressed member is provided with a surface having irregularities on a surface of the member to be foil-pressed, and the foil is pressed on the surface to be foil-pressed with a foil-pressing plate. This is a foil pressing method characterized by processing the surface of the foil into an embossed shape.

In such a configuration, since the surface to be foil formed on the surface of the member to be stamped has irregularities, the foil is stamped on the surface to be foiled to make the surface of the foil uneven. , To be embossed. As a result, it is possible to cope with a change in the embossed design applied to the surface of the foil without using a plurality of foil-pressing plates as in the related art, using only the foil-pressing plate in which the pressing convex surface is formed smoothly. Can be.

Further, it can be proposed that the foil-receiving surface is constituted by a toner layer formed by electrophotographic printing as a suitable means for forming the foil-receiving surface. Electrophotographic printing is a printing method in which a charging drum is charged into a shape such as a character or a pattern, an image is formed by absorbing toner, and the image is transferred to a transfer surface. In addition to the fact that the transferred toner layer has a convex surface, there is an advantage that a foil-pressed member can be easily formed with a surface having irregularities because the transferred toner layer has a convex surface.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. First, as shown in FIG.
An appropriate design 2 composed of characters, designs, and the like is printed on the surface of the member 1 to be foil-pressed, such as paper, by electrophotographic printing. This electrophotographic printing is a printing method using the same principle as a general dry-type electronic copying machine, in which a charged drum is charged into a shape such as a character or a pattern and an image is formed by adsorbing toner, This is a printing method for transferring this to the transfer surface. Then, by printing the design 2 by this electrophotographic printing, the raised toner layer 3 having a thickness of about 10 μm is formed on the member 1. As a result, FIG.
As shown in (1), a foil-receiving surface 4 having unevenness can be formed on the surface of the member 1 to be foil-pressed by the portion where the toner layer 3 exists and the portion where the toner layer 3 does not exist.

Next, as shown in FIG. 2, a foil 5 is placed on the member 1 on which the foil surface 4 is formed, and the foil 5 on the foil surface 4 is pressed while being heated by the foil stamping plate 6. . The foil-pressing plate 6 is used in such a manner that the pressing convex surface 7 protruding in the shape of a character or a pattern to be foil-pressed is formed smoothly, and the shape of the pressing convex surface 7 matches the surface 4 to be foil-coated. . The foil 5 is provided with an adhesive layer 8 on the lower surface and is temporarily attached to the base film 9. Then, in a state where the foil surface 4 and the pressing convex surface 7 are aligned, the foil stamping plate 6 is pressed down to press the foil 5, so that the foil 5
Is pressed only on the surface 4 to be foiled. Here, since the surface of the foil-receiving surface 4 is uneven, the surface of the foil 5 that has been foil-pressed has unevenness, and as shown in FIG. 3, embossing can be performed.

FIG. 4 and FIG. 5 show another embodiment. In this embodiment, as shown in FIG. 4, a design 2 to be printed on the surface of a member 1 is constituted by countless spots 2 '.
By printing this design 2 by electrophotographic printing, an innumerable toner layer 3 corresponding to the spots 2 ′ is formed, and unevenness is formed on the surface of the member 1 to be foil-pressed by a portion with and without the toner layer 3. The surface 4 to be foiled is formed. Then, by pressing the foil 5 on the surface 4 to be foil-pressed by the foil stamping plate 6, as shown in FIG. Shape processing can be performed.

In both of the above embodiments, the case where the foil surface 4 is constituted by the toner layer 3 formed by electrophotographic printing has been described, but the foil surface 4 has a thickness of about 5 μm by screen printing or the like. As described above, it is also possible to form an ink layer having a raised surface and a convex surface.
Here, electrophotographic printing does not require a plate and can easily respond to changes in characters and designs, so that it can be suitably applied to the implementation of the present invention. Further, in the embodiment, the foil 5 having the adhesive layer 8 on the lower surface is used. However, instead of this, the foil 5 without the adhesive layer may be applied by applying an adhesive to the foil-receiving surface 4. .

Further, as the foil stamping plate 6 used for the foil stamping, the foil stamping plate 6 in which the pressing convex surface 7 is formed as described above may be used, so that the uneven foil-receiving surface 4 is not formed on the member 1. In this case, the surface of the foil 5 can be finished smoothly.

[0015]

According to the present invention, as described above, a foil-receiving surface having irregularities is formed on the surface of a member to be foil-pressed, and the foil is pressed on the foil-receiving surface with a foil-pressing plate. Since the embossing process is applied to the surface of the foil, the foil stamping plate used for the foil stamping is also used when the surface design of the foil is changed. It is sufficient to use it, and it is possible to cope with different surface designs without manufacturing a foil stamping plate as in the related art. Thereby, an excellent effect that the plate manufacturing cost can be reduced and the workability can be improved can be obtained.

Further, by forming the foil-receiving surface with a toner layer formed by electrophotographic printing, a printing plate is not required, and it is possible to easily cope with changes in characters and designs, and to transfer images. Since the applied toner layer has a convex surface, the surface to be foiled can be easily formed with a freely designed unevenness on the member to be foil-pressed.
