Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a magnetic card storing information, such as a cash card.

Recently, attention has been paid to magnetic cards of this type in which the printing means is devised so as to eliminate the presence of the magnetic tape attached to the card body.

However, when manufacturing such conventional magnetic cards, it is done by making the center core sheet of the card body the same color as the magnetic tape, and printing desired characters, symbols, etc. on the magnetic tape. As illustrated in FIGS. 1 and 2,
For example, a transparent oversheet 3 is attached to a white center core sheet 2 forming the card body 1,
After pasting the colored magnetic tape 4 thereon, processing is performed by printing with printing ink 5 or by using a center core sheet 2 of the same color as the colored magnetic tape 4. In particular, the center core 2 Since a transparent oversheet 3 is adhered to the surface of the card, a shadow is formed under the printing ink 5 in areas other than the colored magnetic tape 4, creating a hue difference, which makes it possible to identify the presence of the magnetic card. There were some problems such as being easy to use.

The present invention aims to solve the above-mentioned drawbacks of conventional cards, and its gist is that colored magnetic tape is attached to the surface of the card body, which has a transparent oversheet attached to the center core sheet. In the method of manufacturing a magnetic card, the magnetic tape is pasted under pressure along the longitudinal direction, desired characters, symbols, etc. are printed on it with printing ink, and the surface is heated and pressed flush. The card body is characterized by printing ink of the same color as the magnetic tape on the entire surface or a part of the card body excluding the binding area, with the ink partially overlapping both ends of the magnetic tape in the width direction.

The present invention will be described below based on an embodiment shown in FIGS. 3 to 8.

3 to 8 show the manufacturing process of the magnetic card according to the present invention. As shown in FIG. After arranging a magnetic tape 14 colored in a predetermined color along the longitudinal direction on the surface of the main body 10, and applying pressure so that the colored magnetic tape 14 is buried flush within the oversheet 12, , as shown in FIG. 4, the card body 10 excluding the part where the colored magnetic tape 14 is attached.
Ink 15 of the same color as the magnetic tape 14 is printed on the entire surface or part of the magnetic tape 14 by silk printing or offset printing, and the ink 15 is partially overlapped with both widthwise ends 14a and 14b of the magnetic tape 14. . Next, as shown in FIG. 5, the card body 10 is held between, for example, a press plate and heated and pressed so that the layer of ink 15 is flush with the magnetic tape 14, and then as shown in FIG. , then write the desired character (for example, "A,"
B, C, D") or symbols etc. ink 16
A magnetic card as shown in FIG. 8 is obtained by printing the card body 10 and heating and pressurizing it again to make the surface of the card body 10 flush as shown in FIG.

By the way, in the above-described embodiments of the present invention, when heating and pressurizing the card body surface flush, the heating temperature was 140 to 160°C, and the weight was 80 to 100 kg/kg.
The printing ink is pressurized for 4 to 10 minutes at a pressure of cm ² , and the printing ink is an ink containing vinyl chloride as a binder and pigment, for example, titanium oxide for white (for example, manufactured by Toyo Ink Mfg. Co., Ltd.). (product numbers in the 8000s) are used. Further, as a magnetic tape, one having an aluminum layer on the magnetic layer and further coated with colored ink, or one having colored ink coated directly on the magnetic layer are used.

As explained above, according to the present invention, ink of the same color as the colored magnetic tape affixed to the surface of the card body is printed on both ends of the colored magnetic tape in the width direction so as to partially overlap each other, so that the tape is flush with the colored magnetic tape. Since the magnetic tape is heated and pressed, there is no difference in hue between the area where the tape is attached and the other areas, unlike in the past, and shadows are created, creating the illusion that the magnetic tape is not attached at all. It has a very unique effect in terms of design, such as making the tape on the card almost invisible to the viewer.

Claims (1)

[Claims] 1. Paste colored magnetic tape along the longitudinal direction of the card onto the surface of the card body, which has a transparent oversheet attached to the center core sheet, and print desired characters, symbols, etc. on it with printing ink, and In a method of manufacturing a magnetic card in which the surface is heated and pressed flush with the surface of the card, ink of the same color as the magnetic tape is applied to the entire or part of the card body, excluding the area where the magnetic tape is attached, to both edges in the width direction of the magnetic tape. A method for manufacturing a magnetic card, which is characterized in that the card is printed with a partial overlap, and then heated and pressed to make the card surface flush.
