Abstract

PURPOSE:To easily change the pattern of a magnetic card by forming a monochromatic ground on the magnetic card and printing out an image on the ground. CONSTITUTION:A magnetic layer 2 and a protection film 3 are formed on one face of a magnetic card and a printing layer 4 is formed on the other face. A monochromatic coating layer 5 is formed on the film 3 layer 4 and a printing layer 6 having a required image is formed on the layer 5 preferably by offset print. Consequently, a required pattern can be printed out on the magnetic card without damaging the layer 2 and sharply changing the thickness of the card.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of printing a magnetic card, and particularly to a method of printing a predetermined multicolor image by forming a base on the printing surface.

(Prior art) In recent years, it has become increasingly common to provide certain services by using cards on which monetary information is magnetically recorded instead of cash.

These magnetic cards usually have various designs printed on one side, and precautions for handling or using the magnetic card are written on the back side. The design printed on the front side is printed together with the magnetic recording section by the card system providing the service, but the card purchaser can also specify the design.

(Problem to be Solved by the Invention) This type of magnetic card is produced by simultaneously printing multiple cards on a single synthetic resin film and then cutting it into individual cards. . Therefore, if you try to print a unique design on a magnetic card that has been divided into pieces about the size of a hand, it will be difficult to accurately position and feed the paper into the printing machine, and the printing ink will run out. Since the thickness of the card is increased, there is a risk that it will no longer meet the standards of a handling device capable of reading information from the card. It is conceivable to scrape off the first printed surface and then print again, but there is also a risk of damaging the magnetic recording section. As described above, under the present circumstances, it is extremely difficult to reprint separate cards into individual cards to create a different design from the previous one.

The present invention has been made in view of the above points, and aims to provide a magnetic card printing method for changing the design of the magnetic card and printing an additional multicolor image on the back side of the card. .

(Means for Solving the Problems) The magnetic card printing method of the present invention includes a first step of forming a monochrome base on a magnetic card having a magnetic recording part, and a multicolor image being formed on the base. A magnetic card printing method is characterized in that it comprises a second step of printing, and further characterized in that said second step is performed by offset printing.

(Function) In the magnetic card printing method of the present invention, since a monochrome base is formed on the magnetic card, the originally drawn pattern can be erased without significantly increasing the thickness of the card itself.
Additionally, the card user can write their own designs.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1(a) shows a partial cross section of a magnetic card such as a telephone card for a public telephone. film 1
is a thin film made of synthetic resin, and a magnetic layer 2 is formed on the top surface in the figure, and magnetic data indicating the number of times the card has been used is recorded thereon. The protection Di 3 protects the recording portion of the magnetic layer 2 from being damaged due to repeated reading and writing of magnetic data, and handling precautions are further printed on this protective film. A printing layer 4 is provided on the opposite side of the film 1 from the magnetic layer 2, and this side is usually referred to as the front side.

FIG. 1(b) shows a cross-section of the telephone card additionally printed by the cardholder. A coating layer 5 is formed on the entire surface of the protective film 3, and a printing layer 6 is provided thereon. This printing layer 6 is formed thinly for each sheet by manual feeding using an offset multicolor printing machine, and is printed including the data recording surface. The coating layer 5 is printed twice using a fresh dry method using a two-component thermal ink of gold/medium and silver paste, for example, and a rough white ink is printed multiple times to create a single-color solid base. is formed.

If a plain base is formed in this way and then multicolor offset printing is performed on it, the color tone will be clear even if the thickness of the ink layer is sufficiently small. Furthermore, since this coating layer 5 protects the magnetic layer 2 together with the protective film 3 during alignment in an offset rotary press, there is no risk of destroying magnetic data. FIG. 2 is a flowchart showing the procedure for printing such a magnetic card.

Note that the protective film 3 formed as a base may be formed only on the magnetic recording part of the magnetic layer 2, or it may be formed on the first printing layer 4 on the surface so that offset printing can be performed on both sides. You can also go to

In other words, the Ishii Fura Card is used not only as a telephone card for Imasa Gorai Gentenki, but also in vending machines for various tickets and goods, and it magnetically writes and reads data into the magnetic recording section. Because the printing method described above does not damage the magnetic recording area and does not significantly change the thickness of the card, cardholders can print their own images regardless of the card system. It can still be used as a unique advertising medium and can be used effectively as a unique advertising medium.

Although one embodiment of the present invention has been described above, various different embodiments can be easily constructed without departing from the spirit of the present invention. The present invention is not limited to the embodiments.

(Effects of the Invention) According to the present invention, it is possible to provide a method for printing a magnetic card, in which the design of the magnetic card can be easily changed.
