Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention makes a magnetic card with visual information that reduces wear and damage to a magnetic strip and enhances the visual hiding effect of the magnetic strip. It is about the method.

[Prior Art] Conventionally, various methods for producing a magnetic card have been proposed in which visual information is provided and the magnetic band portion is not easily visible.

A typical example of this is that an uneven base layer is provided on the surface of a card substrate, a magnetic band is provided in the concave portion of this layer, a coating layer is provided on this upper surface, and visual information is provided on the upper surface or other surface. A magnetic card is created, or a magnetic card is created by sequentially providing a magnetic band, a covering layer, and visual recognition information without providing the uneven base layer described above.

[Problems to be Solved by the Invention] In the method of forming the above-mentioned magnetic card, in the method of providing the uneven base layer on the surface of the card substrate so that the magnetic band does not protrude, the method and apparatus for making the same become complicated, and the card Since the surface material is limited, it is not possible to inexpensively make a card, and the step of providing visual information on the upper surface or the other surface of the coating layer is a single step. However, the printing means was limited due to the thickness of the sheet, which was inconvenient.

Further, in the method of sequentially providing the magnetic band, the coating layer, and the visual information on the surface of the card substrate, the magnetic band and the coating layer protrude from the surface of the card substrate, and there is no concealment effect of the magnetic band, and there is no magnetic field in the coating layer. If the coating layer is thickened and the upper surface of the coating layer is made flat so that the strip is filled, not only is it inconvenient because the electrical conversion characteristics of read / write to the magnetic strip are poor, but also for providing visual information. There were inconveniences more than the above-mentioned conventional example.

Therefore, in the present invention, the above-mentioned conventional problems are eliminated, it is easy to produce, it is adaptable to all card substrate materials, it can be produced efficiently and economically, and the wear and damage of the magnetic band portion is prevented. An object of the present invention is to provide a method of making a magnetic card that is less and easily improves the visual hiding effect.

[Means for Solving the Problems] In order to achieve this object, the present invention provides a smoothing layer on the upper surface of a card substrate, and then a magnetic band and a protective band are formed on the upper surface of the smoothing layer so as to be adjacent to each other. The protective band and the visual information were simultaneously printed by the same printing device when the protective band and the protective band were provided at the same height, and then a coating layer was formed on the upper surfaces of the magnetic band and the protective band.

[Operation] As described above, according to the present invention, since the smoothing layer is first provided on the card substrate, fine irregularities on the card substrate are smoothed, and the magnetic band and the protective band are provided at a uniform height (thickness). Further, since the visual recognition information is provided simultaneously with the protective band by the same printing device as the protective band, it is possible to easily print on the card substrate surface without being affected by the height of the magnetic band and the covering layer without increasing the number of steps. .

Further, since the coating layer is provided on the upper surface where the magnetic band and the protective band have substantially the same height, the coating becomes easy and the coating can be performed at a uniform height.
