Abstract

PURPOSE:To provide a method for stamping to print to appear a true stamping image with a low cost. CONSTITUTION:The method for generating a stamping image printing effect with a deposited plastic film comprises the steps of printing a design of a stamping image with transparent inks 20, 21 on a surface of a deposited plastic film 14, backing printing a rear side of the deposited surface with color inks 17, 18, 19 and white ink 16, then pickling it to wash away the deposited surface, and then laminating a sealant film to the backing printed surface as a product.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of producing a printing effect of a foil stamped image by a vapor-deposited plastic film.

[0002]

2. Description of the Related Art There are the following methods for printing a foil stamped image, that is, a method for producing a metallic image by a conventional printing technique.

A. A method of creating a close metallic image with printing ink.

B. Ordinary printing is applied to the plastic film, and the window is opened without applying ink to only the metallic image part, or transparent ink is used only for this metallic image part, and a vapor deposition film is later attached to create a metallic image. Film bonding method.

C. After printing on plastic film,
A method to create a metallic image by stamping and printing in a separate process.

D. A sea light processing method in which a film is printed with an oil-based ink and a water-soluble ink, and then vapor deposition and washing are performed to partially vaporize.

E. A pasta processing method in which transparent ink and opaque ink are printed on the vapor-deposited surface of the vapor-deposited film, and the vapor deposition is melted with an acid and allowed to flow, leaving the vapor deposition partially.

[0008]

However, the above method has the following drawbacks.

First, the substitution of printing ink does not give a deep and true metallic feeling. Further, in the vapor deposition film laminating method or the sealite / paster processing, since the layers are laminated, the cost becomes high, and the texture of the waist of the film also changes. In addition, the foil stamping image fades because the deposition is seen through the film. The foil stamping method is slow in working speed, which causes the price to be high. Furthermore, when heat-shrinking film (such as polyvinyl chloride / polypropylene / polystyrene / polyethylene terephthalate is used as heat-shrinkable plastic film) is hot-printed, heat is applied to stamp it, so the risk of shrinking the film. Therefore, temperature control becomes very difficult.

It is an object of the present invention to propose a method for producing a foil stamping effect with a vapor deposited film which has a true metallic image and can be processed at a low cost.

[0011]

The method of producing a foil stamping printing effect by the vapor deposition film according to the present invention is as follows.

A pattern of a foil stamping image is printed on the vapor-deposited surface of the vapor-deposited plastic film, then the back side of the vapor-deposited plastic film which is not vapor-deposited is back-printed, and then a pattern is printed by pickling. A method of producing a printing effect of a foil stamping image by using a vapor-deposited plastic film, which is characterized in that only the vapor-deposited surface part is left.

[0013]

[Function] On the vapor-deposited surface of the vapor-deposited plastic film, a pattern (including characters) of a foil stamping image is printed by gravure printing or offset printing.

Then, the film is turned over and the back side is back-printed. This back printing can also be performed by gravure or offset printing. Next, by pickling with hydrofluoric acid or the like, only the pattern is left on the deposition surface.
When viewed from the vapor deposition surface side, this is a foil stamping image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of producing a printing effect of a foil stamp image of the present invention will be described with reference to FIGS. In the figure, 14 is a vapor-deposited metal layer, 15 is a polyester film, 16 is white ink, 17, 18 and 19 are color inks, 20 and 21 are transparent inks (medium, transparent yellow ink, etc.), and 22 is a sealant film (polyethylene). Etc.), 23, 28 and 29 are heat seal parts (transparent part without ink), 24 and 26 are metallic tone parts (transparent ink part), 25 is each color ink, 2
7 is white ink, which is processed by the following method.

First, the polyester film 15 on which the vapor-deposited metal layer 14 is formed using gold, silver, aluminum, copper, nickel, tin, chromium, zinc, etc. is foil-pressed by gravure printing on the side opposite to the vapor-deposited metal layer 14 (back surface). Each color ink 17, 18, 19 which is a pattern of an image is printed, and the back printing is performed with a white ink (FIG. 1). Next, the film is turned over and a pattern of a foil stamping image is printed on the vapor-deposited metal layer 14 using the transparent inks 20 and 21 (FIG. 2). Next, pickling with hydrofluoric acid is performed to wash away the vapor-deposited metal layer other than the transparent ink 20, 21 portions (FIG. 3). Next, a sealant film 22 is attached to the surface of the white ink 16 if necessary.

In the above processing, the steps of FIGS. 1 and 2 may be reversed, and the order is not limited in the present invention.

FIG. 5 shows a pillow bag manufactured by using the above-mentioned foil stamping image film, and a true foil stamping image appears in the appearance.

[0019]

As described above, according to the present invention, since the foil stamping image can be produced by using the printing method, the productivity is high and the processing cost is low. In addition, the foil stamped image has an extremely beautiful finish including its color and edging.
