Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the creation of a magnetic card with visible information that reduces wear and damage to the magnetic strip portion and enhances the visual concealment effect of the magnetic strip portion. It is about the method.

[Prior Art] Various methods have been proposed in the past for producing magnetic cards in which visual recognition information is provided so that the magnetic band portion is not easily visible.

A typical example is to provide an uneven base layer on the surface of the card board, provide a magnetic band in the recessed part of this layer, provide a covering layer on the top surface, and provide visual information on the top surface or other surface. Alternatively, a magnetic card can be created using the above-mentioned method without providing the uneven underlayer, and the magnetic strip can be covered with 8! Magnetic cards were created by sequentially providing layers and visibility information.

[Problems to be Solved by the Invention] In the production of the above-mentioned magnetic card, the method of providing an uneven base layer on the surface of the card substrate so that the magnetic band does not protrude requires a complicated production method and equipment, and Because the surface material is limited, not only can cards not be produced at low cost, but the process of providing visible information on the top surface of the covering layer or the other side is a separate process, and when providing this on the other side, the covering layer It was inconvenient that printing methods were limited due to the thickness of the paper.

In addition, in the method of sequentially providing a magnetic band, a coating layer, and visual information on the surface of a card substrate, the magnetic band and coating layer protrude from the surface of the card substrate, there is no effect of hiding the magnetic band, and there is no magnetic field in the coating layer. If the coating layer is made thicker and the upper surface of the coating layer is made flat so that the strip is buried, the electrical conversion characteristics of the magnetic strip will deteriorate, which is not only inconvenient, but also
Providing visual recognition information is also more inconvenient than the conventional example described above.

Therefore, the present invention eliminates the above-mentioned conventional problems, is easy to produce, is adaptable to all card substrate materials, is efficient and economical to produce, and also prevents wear and damage on the magnetic strip portion. An object of the present invention is to provide a method for producing a magnetic card that can easily improve the visual concealment effect with less noise.

Means for Solving Problem L] In order to achieve this object, the present invention simultaneously prints a smooth opening and visual recognition information on the upper surface of a card board using the same printing device, and then A magnetic card was prepared by providing a magnetic band and a protective band adjacent to each other at approximately the same height, and then providing a coating layer on the upper surfaces of the magnetic band and the protective band.

[Function] As described above, in this invention, since the smoothing layer and the visual information are first provided on the card substrate, fine irregularities on the card substrate are smoothed out, and the magnetic strip and the protective strip can be made to have a uniform height and thickness. In addition, since the visual information is printed simultaneously with the smooth layer using the same printing device, there is no additional process and it is easy to print on the surface of the card board without being affected by the height of the magnetic strip. .

In addition, since the coating layer is provided on the upper surface of the magnetic band and the protective band, which have approximately the same height, the coating becomes easy and can be coated at a uniform height.

[Example] The present invention will be described with reference to drawings showing examples of the invention.

FIG. 1 is an explanatory diagram of a method for producing a magnetic card according to the present invention, and the explanation will be given with reference to FIG. 2 and subsequent figures showing cross sections of the processed state in each part of this diagram.

In FIG. 1, a card substrate 1 made of continuous card paper is sequentially transferred in a continuous state, and a printing device 2 having a plate for printing a smooth layer 11 and visible information 12 prints a card substrate 1 as shown in FIG. Apply ink to a predetermined position on the surface of the smooth layer 11 to provide a smooth layer 11 and visual recognition information 12, and then print the smooth layer 11 at a predetermined position using a printing device 3 having a plate for printing a magnetic strip 13, as shown in FIG. A printing device 4 having a plate for printing a protective band 14 on the top surface of the smooth layer 11 and adjacent to the magnetic band 13, as shown in FIG. A protective band 14 is provided at approximately the same height as the magnetic band 13.

Then, as shown in FIG. 5, the printing device 5 applies coating ink to the upper surfaces of the magnetic strip 13 and the protective strip 14 to form a coating layer 15, and then, if necessary, the upper surface of the coating layer 15 is Then, as shown in FIG. 6, a printing ink with a different color tone from that of the coating layer 15 is applied by the printing device 6 to provide additional visual information 16, and then cut to a predetermined size by the cutter 111Fi device 7, as shown in FIG. A magnetic card 1o as shown in is obtained.

In the above, instead of the card paper used for the card substrate 1, a coloring agent FJ8 which develops color when the surface is subjected to recording conditions such as heat or pressure is provided, and a well-known coloring material having fine irregularities on the surface is provided. Even when the recording card substrate 1- is used, as shown in FIG. A magnetic card 20 for recording can be easily obtained by providing a magnetic strip 13 and a protective strip 14, and then forming a coating layer 15 and additional visible information 16 on the upper surface of these. It will be done.

Furthermore, in the present invention, in addition to the above-mentioned card substrate, it is possible to use high-quality paper, medium-quality paper, or synthetic paper, a synthetic resin sheet, or a blue sheet thereof having fine irregularities on the surface.

In addition, visibility information 12 and additional visibility information 1 in this invention
6 refers to something that can be visually recognized, such as a collection of characters, symbols, designs, dots, lines, etc. for preventing forgery, and this visibility information includes information such as information provided on the edge side of the smooth layer 11, as shown in FIG. When these are roughly covered with a protective band 14 and/or a covering layer 15, this? It is preferable to use transparent ink that allows the JL recognition information 12 to be visually recognized.

Furthermore, as the printing means mentioned above, known printing means such as gravure printing, offset printing, letterpress printing, silk screen printing, and inkjet printing can be used.
It is important to print the smooth layer 11 and the visible information 12 at the same time using a peripheral printing device.
, or to the same flat body (plate, screen surface), etc., can be easily done by one rotation, pressing, printing control of the screen surface, etc. with respect to a predetermined printing surface.

In the above, the smooth layer 11 and the visible information 12 are provided at a distance of about several μm to 10 μm, and the magnetic band 13 and the protective band 14 are
is provided with a thickness of about 10 μm to 30 μm, and the coating layer 15 has a thickness of about 5 μm.
μm to about 15 μm, additional visibility information 16 is from several μm to 1
It is sufficient if they are provided at about 0 μm, and when these are provided,
If the ink cannot be applied high enough in each single printing, an additional printing device 3.4 of the same type is installed after each of the printing devices 3.4 in Fig. 1, and the printing device 3.4 is installed again after printing once. If it is necessary to apply the ink at a higher level, a known method such as using a nozzle application means that discharges ink from a flat nozzle in accordance with the transport speed of the card substrate 1 in place of the above-mentioned printing means may be used. It may be provided by the following means.

Further, the magnetic band 13 mentioned above is mainly made of magnetic ink in which magnetic material powder such as magnetic iron oxide is dispersed.
Smooth layer 11,? The J2 certification information 12, the protective layer 14, the coating layer 15, etc. are inks mainly composed of pigments and vehicles,
These may be the same color, but the magnetic band 13 is usually brown or black, and if the protective band 14 and the magnetic band 13 are made the same color so that they cannot be distinguished from this magnetic band 13, the appearance of the magnetic card will change. Taking this into account, the coating layer 15 may be colored in white, silver, gold, or the like, and the visual information 12 may also have a desired color tone. In this case, the same ink can be used for the visual recognition information 12 and the smooth layer 11.

[Effects] As described above, in this invention, a smooth layer is provided on the fine irregularities of the card substrate, and a magnetic band and a protective band are provided thereon, so it is easy to provide a magnetic band and a protective band of a desired height. As a result, a magnetic card with good magnetic-to-electrical conversion characteristics can be obtained, the card substrate can be easily selected, and since visual information is provided at the same time as the smooth layer, there is no increase in the number of steps, and the magnetic strip, coating layer, etc. Since printing can be performed without being affected by the height, it can be easily installed using any desired printing means and is extremely economical.

In addition, since the coating layer is provided on the upper surfaces of the magnetic strip and the protective strip, which are made to have approximately the same height, unlike a coating method that covers an uneven surface and makes the upper surfaces of the protective strip have the same height, it can be easily coated with a desired printing method. This makes it possible to reduce the height and thickness of the coating, which improves the magnetic-to-electrical conversion properties.Furthermore, the unevenness of the magnetic strip does not appear on the card surface, reducing wear and tear on the magnetic strip.
It has the characteristics of being able to easily obtain a good-looking magnetic card at a very economical cost, such as less damage and a higher concealment effect since no irregularities appear.
