Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a photographic card for forming a photographic image with gradation, particularly a face photographic image, on cards such as identification cards or credit cards.

Conventionally, the method of forming photographic images on cards requires special processing in the pre-process, which requires special equipment.
However, manufacturing loss cards cannot be reused; for example, transfer methods such as forming an image on special photosensitive paper, transferring it to a credit card coated with adhesive, and protecting it with a transparent film from above are used. Alternatively, an engraving method in which ink is fixed on the photo holder using silk screen printing and the surface is scraped off using a photoelectric method using a special machine, or a photo printed on photographic paper is placed in bone white vinyl chloride and transparent vinyl chloride and then laminated. The photo insertion method, etc. requires special equipment and equipment, making it impossible to reuse failed products and making it difficult to manufacture easily.

The present invention makes it possible to easily and efficiently form images with density gradations on cards such as identification cards or credit cards using a printing method, and to form images with wear resistance.

The present invention allows desired characters to be printed on a bone white vinyl chloride substrate.
For cards that have been printed with symbols, marks, etc. and pasted with transparent vinyl chloride from the front and back, after printing a photographic image such as a face photograph on the surface of the card,
This photo card is made by dry laminating a synthetic resin protective film coated with adhesive from the back side onto the image.

To explain the photo card of the present invention in detail, as shown in Fig. 1, desired characters, symbols, and marks 3 are printed on the front and back sides of a card-shaped bone white vinyl chloride 2, and a transparent vinyl chloride 1 is pasted on the surface. A photographic image 5 is printed on an appropriate part of the vinyl 1 using a printing method.
is printed, and a protective film 6 made of synthetic resin coated with an adhesive 7 from the back side is heat-laminated onto the image 5.

The method of manufacturing photo cards according to the present invention will be explained based on the manufacturing process shown in FIG. Afterwards, using the mask plate 9 provided with the white areas 8 shown in FIG. 4 in the size to be reproduced on the card and the negative film obtained from the original, for example, a 30-screen polyhedral halftone decomposition positive image is photoengraved. . This is printed onto a presensitized printing plate, which is mounted on an offset proofing machine or a circular pressure printing machine and printed. When printing is carried out on a card punched to the desired size and made of a somewhat thick substrate such as bone white vinyl chloride on which letters, symbols, and marks 3 are displayed, it is necessary to ensure that the photographic image is placed in the appropriate position on the card. In addition, a printing frame 10 for inserting a card as shown in FIG. 5 is prepared so that printing can be performed with proper registration in the case of multicolor printing. The printing frame 10 is
Concave portion 11 divided into multiple sections similar to multi-sided plate making
For example, 30 punched cards 4 are framed and printed by fixing a printing frame 10 on a printing machine.

The protective film 6 of the photographic card of the present invention is dry laminated on the photographic image layer 5 formed by a printing method to protect the ink layer, and is preliminarily coated with a solvent-vaporizing adhesive on a synthetic resin film such as polypropylene. The protective film 6 coated with the agent 7 is heated and laminated so as to cover the ink layer portion. As shown in FIG. 1, the printing card 4 has a structure in which transparent vinyl chloride 1 is bonded from the front and back to a somewhat thick substrate such as bone white vinyl chloride 2 on which characters, symbols, and marks 3 are displayed, as described above. The protective film 6 will be dry laminated to the top layer of transparent PVC 1.
Due to the heating lamination, the protective film 6 bites into the transparent vinyl chloride 1, so that the protective film 6 protrudes only slightly at the minimum layer, and the outer shape of the card 4 becomes relatively flat. It is convenient in terms of top and appearance.

According to the present invention, it is possible to insert a photo into a card 4 on which characters, symbols, and marks 3 are displayed in small pieces, and compared to methods such as a transfer method, an engraving method, and a photo insertion method, printing is possible. Because it can be carried out using a special engraving device, or equipment required for transfer preparation and transfer printing device, etc., if the card is printed with characters, symbols, marks, etc. in advance and then cut into small pieces and then the photo is inserted. It has the advantage that it can be carried out consistently with printing without the need for However, with the method of the present invention, the image printed on the card surface can be removed with volatile oil or the like and reused, and the protective film can be used to remove the printed image formed on the card. By laminating only the surface, the printed image can be easily and completely protected, and the manufacturing cost can be greatly reduced.

Claims (1)

[Claims] 1. Desired characters, symbols,
After printing a mark, etc. on a card and pasting transparent vinyl chloride on the front and back sides, a density gradation image such as a photographic image is displayed on the card surface using a printing method, and then an adhesive is applied from the back side onto the image. A photo card with a dry-laminated synthetic resin protective film. 2. A printing plate in which multiple sections are made into multiple sections according to the photo manuscript, with the standard dimensions of the card as one section;
