Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foil pressing method capable of embossing a freely designed and freely designed surface of a foil to be pressed.
[0002]
[Prior art]
In order to enhance the decorativeness of various brochures and tickets, and to prevent counterfeiting, it is known to stamp characters and designs on paper such as brochures and tickets.
[0003]
Conventionally, such a foil pressing operation is performed by placing a foil having an adhesive layer on the lower surface on a member to be pressed, such as a paper surface, and the foil pressing plate having a pressing convex surface protruding in a shape such as a character or a pattern. By pressurizing while heating the foil, the foil is joined to the member in accordance with characters and designs via an adhesive layer.
[0004]
Further, when the surface of the foil to be pressed is finished smoothly, the surface is processed using a foil pressing plate having a pressing convex surface formed smoothly. In addition, when embossed processing is performed on the surface of the foil to be pressed, the surface of the foil at the time of pressurization can be obtained by using a foil stamping plate with irregularities of the required design consisting of letters and designs on the pressing convex surface. The required irregularities are produced in the.
[0005]
[Problems to be solved by the invention]
In the conventional foil stamping method as described above, each time the surface design of the foil is changed, a foil stamping plate has to be manufactured each time. Therefore, the manufacturing cost is high, time and labor are required, and workability is poor. There was a problem.
[0006]
The object of the present invention is to provide a foil pressing method capable of solving such conventional problems.
[0007]
[Means for Solving the Problems]
According to the present invention, the toner layer is partially formed by electrophotographic printing on the surface to be foil-foiled of the member to be pressed, so that the unevenness is formed by the portion with and without the toner layer, and the pressing convex surface is formed smoothly. A foil pressing method characterized by processing the surface of the foil on the surface to be embossed into an embossed shape by heating and pressing the foil having an adhesive layer on the lower surface on the surface to be foil pressed with a foil stamping plate. is there.
[0008]
In such a configuration, since the foil surface formed on the surface of the member to be pressed has irregularities, by pressing the foil onto the foil surface, the surface of the foil becomes irregular and embossed Will be processed. By using only a foil stamping plate with a smooth pressing convex surface, it is possible to respond to changes in the embossed design applied to the foil surface without producing multiple foil stamping plates as in the past. Can do.
[0009]
Moreover, it can be proposed as a suitable means for forming the foil surface that the surface to be foil is composed of a toner layer formed by electrophotographic printing. Electrophotographic printing is a printing method in which an electrified drum is charged into a shape such as letters or designs, and an image is formed by adsorbing toner, and this is transferred to the transfer surface. Furthermore, since the transferred toner layer has a convex surface, it is possible to easily form a foil surface having irregularities on the member to be pressed.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
In the following, an embodiment of the present invention will be described with reference to FIGS.
First, as shown in FIG. 1, an appropriate design 2 made of characters, designs, etc. is printed on the surface of a 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 electronic copying machine, and forms an image by charging a charging drum into a shape such as a character or a design and adsorbing toner, This is a printing method in which this is transferred to the transfer surface. Then, by printing the design 2 by this electrophotographic printing, a toner layer 3 that rises to a thickness of about 10 μm is formed on the member 1. As a result, as shown in FIG. 1, a foil-coated surface 4 having irregularities can be formed on the surface of the member 1 to be foil-pressed by a portion where the toner layer 3 is present and a portion where the toner layer 3 is not present.
[0011]
Next, as shown in FIG. 2, the 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 press plate 6. In this foil stamping plate 6, a pressing convex surface 7 projecting 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 foil surface 4. . The foil 5 is provided with an adhesive layer 8 on the lower surface and is temporarily attached to the base film 9. And in the state which aligned the to-be-foiled surface 4 and the pressing convex surface 7, the foil 5 is crimped | bonded only on the to-be-foiled surface 4 via the contact bonding layer 8 by pressing down the foil press plate 6 and pressurizing the foil 5. The Rukoto. Here, since the surface of the foil surface 4 is uneven, unevenness is generated on the surface of the foil 5 pressed, and embossed processing can be performed as shown in FIG.
[0012]
4 and 5 show another embodiment. In this embodiment, as shown in FIG. 4, the design 2 printed on the surface of the member 1 is constituted by countless spots 2 ′. By printing this design 2 by electrophotographic printing, an infinite number of toner layers 3 corresponding to the spots 2 ′ are formed, and the surface of the member 1 to be pressed with foil is uneven by the portions where the toner layer 3 is present and not. The foil surface 4 to be formed is formed. Then, by pressing the foil 5 on the surface 4 to be foil-foiled by the foil stamping plate 6, innumerable irregularities are generated on the surface of the foil 5, as shown in FIG. Can be processed.
[0013]
In the above-described embodiments, the case where the foil-coated surface 4 is constituted by the toner layer 3 formed by electrophotographic printing has been described. However, the foil-coated surface 4 swells with a thickness of about 5 μm or more by screen printing or the like. It is also possible to configure with an ink layer having a convex surface. Here, since electrophotographic printing does not require a plate and can easily cope with changes in characters and designs, it can be suitably applied to the implementation of the present invention. Further, in the examples, the foil 5 having the adhesive layer 8 on the lower surface was used, but instead of this, using the foil 5 on which the adhesive layer was not formed in advance by applying an adhesive to the foil surface 4 , It is also possible to crimp this .
[0014]
Moreover, since the foil stamping plate 6 used for foil stamping should just use the foil stamping plate 6 in which the pressing convex surface 7 was formed smoothly as mentioned above, when not forming the uneven | corrugated foil surface 4 on the member 1 The surface of the foil 5 can be finished smoothly.
[0015]
【The invention's effect】
As described above, the present invention forms a foil surface having irregularities on the surface of a member to be foil-pressed, and presses the foil onto the surface to be foil-pressed with a foil-pressing plate so that the foil surface on the surface of the foil is pressed. Since it is a foil stamping method that has been embossed, even when changing the surface design of the foil, the foil stamping plate used for foil stamping may be a foil stamping plate with a smooth pressing convex surface. Thus, it is possible to cope with different surface designs without producing a foil stamping plate. Thereby, the outstanding effect which can reduce plate manufacturing cost and can improve workability | operativity is acquired.
[0016]
Further, by forming the surface to be coated 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 transferred toner. Since the layer is convex, it is possible to easily form a surface to be foil provided with irregularities of free design on the member to be pressed.
