2 to 4, first, the pure gold is rolled by a rolling roll to form a pure gold foil 12 having a thickness of 0.2 to 0.25 mm, and the overlay film 14 on the upper and lower surfaces of the pure gold foil 12. After placing it again, by using a rolling roll (Roll raminator) by the overlay film on the upper and lower surface of the pure gold thin plate to produce a pure gold sheet 10 (S10).

Next, various patterns, figures, logos, etc. are produced on the pure gold sheet 10, and a new coarse transparent sheet is produced. Before the transparent sheet is produced, the pattern to be put on the transparent sheet is changed into a film state and the film is used. The plate making process to prepare for printing (S20).

Next, using the printing film produced through the plate making process to produce an offset (offset) printing or silk printing to produce the front and rear transparent sheets 20a, 20b engraved with the drawings, figures, logos (printing step; S30 ), The adhesive layer is formed by applying an aqueous or oil-based adhesive on both sides of the front and rear transparent sheets 20a and 20b produced through the printing step (S30) (S40).

Subsequently, the magnetic wire 22 is placed on the rear transparent sheet 20b to be bonded to the back of the pure gold sheet 10 among the transparent sheets produced through the printing step S30, and the overlay film 24 is placed thereon. The magnetic film 30 is formed (transfer operation; S40).

Subsequently, the front transparent sheet 20a and the magnetic film 30 are laminated with the pure gold thin sheet 10 therebetween, and the upper surface of the front transparent sheet 20a and the bottom surface of the magnetic film 30 are printed on a transparent sheet. After stacking the transparent protective sheet 40 to protect the printed surface is neatly trimmed and subjected to the matching process of contact bonding each sheet (S50). At this time, in the matching process, each sheet is temporarily bonded through a rolling roll using a roll raminator.

 The raw material including the pure gold foil sheet 10, the transparent sheets 20a and 30 (including the magnetic film) and the protective sheet 40 that are temporarily bonded through the matching is put into a press at a low temperature and high pressure state and pressurized to be thermally bonded (S70). ). This pressing adheres each sheet step by step over four orders, and the temperature of the press may be set between 70 ° C and 110 ° C. If it is set to less than 70 ℃ adhesive strength is not properly melted in the adhesive coating process (S40), the adhesive strength is lowered, if the temperature is more than 110 ℃ pure gold plate 12 is cracked or cracked due to high temperature heat of the press may cause product defects Because it can.

Subsequently, the sheet heat-bonded through the pressing process is cut out according to the standard of the card through a punching machine (S80), and the hologram and silver foil or gold foil of various shapes are formed on the front and back of the card cut to the standard through the punching step. Card production is completed through a stamping process (S90) for attaching a signature plate made of such.

On the other hand, the IC card is manufactured by planting the IC chip on the finished gold credit card through the above process, in order to make the IC card after adjusting the thickness of the overlay film 14 or 24 in the above-described matching process, It is manufactured by inserting grooves of the size and depth of the corresponding IC chip on the finished card and inserting the IC chip in the groove. The process of selling grooves on the card for the IC chip installation is referred to as forming, and when such forming is added, gold IC cards as well as gold credit cards can be mass-produced in the existing process.

And, in the process of printing using the printing film produced through the engraving process (S20) of the production process of the above gold card, the printing (offset) or silk printing to the front, back, transparent sheet for the figure, figure, logo, etc. It is also possible to manufacture a gold business card card with a relatively thin thickness on the back side of the surface, that is, the surface to be in contact with the pure gold sheet.

Here, the gold business card is not required for the above-described protective sheet 40 for protecting the printed layer because the pattern, figure, road, etc. are engraved on the back of the transparent sheet as described above. In addition, the adhesive layer for bonding to the pure gold thin sheet may also be formed only on one surface.

Hereinafter, the gold card manufacturing method of the present invention will be described in more detail with reference to embodiments of the present invention.

<Example>

The pure gold is rolled on a rolling roll to produce a thin plate having a thickness of 0.2 to 0.25 mm, and the overlay film is laminated on the upper and lower surfaces of the thin gold plate, and then the overlay film is attached using a roll laminator. To form the pure gold sheet.

Upon request of the card company's production, the requested design is designed according to the card standard, and the design and color are edited to make the gold effect stand out. At this time, it is important to reduce the image or to use halftones and gradation so that the golden divergence effect is highlighted. When the editing is completed, the film and the printing plate are output using the output device.

In accordance with the card size, 3cm * 7cm, the offset work is used to make PS plates for offset printing and positive films for silk printing.

Gold offset cards (0.20mm thick) are printed on the front of the transparent sheet (normal quick printing) by using offset-set printing or silk printing, and gold business cards (0.13mm thick) are on the back of the transparent fabric. Print on

The transparent sheet, which has been printed (inserted the pattern, symbol, logo, etc. requested by card companies, banks, companies, etc.), is coated on both sides with a silk printing method. However, in the case of gold business card, the adhesive is applied only to the back printing surface.

The magnetic stripe transfer on the rear transparent sheet uses a roll overlay sheet of 0.06 mm. Magnetic color has a number of primary colors such as gold, silver, black, etc., but in the case of the pure gold card applied in the present invention, gold is applied to emphasize the gold effect.

Check the print defect on the front and back transparent sheets which have been printed. This is to prevent the defect of the expensive pure gold sheet by preventing the printing of the defective fabric in advance in advance.
