Description

Three-dimensional plastic card and its manufacturing method {STEREOGRAPHIC PLASTIC CARD AND METHOD OF FORMING THE SAME}

The present invention relates to a three-dimensional plastic card and a manufacturing method thereof, and more particularly, to a three-dimensional plastic card with a hologram foil attached to the front of the card and a manufacturing method thereof.

In general, plastic cards are financial cards such as bank cards, securities companies, credit card companies, etc., financial cards such as credit cards, stock cards, etc., membership cards used in various shopping malls, mobile operators, hospitals, and so on. A card that refers to the identification card to use a place.

Such plastic cards usually overlap opaque polyvinyl chloride (PVC) sheets with magnetic stripe sheets, which store customer's billing or usage information, to form the card's appearance, and the card issuer is placed in front of the card issuer. The hologram is attached and the back side is manufactured by attaching a sine column and the like. Since the hologram image attached to the front is optically generated and reproduced, it cannot be forged by conventional printing. That is, varying rainbow colors and three-dimensional impressions, when copied by a color copier or a precision scanner, only part of the optical information is printed to obtain an image different from the original hologram. The hologram on the credit card uses natural light as a reflection type, and is generally attached using a hot stamping foil method.

However, the card made of such a conventional opaque PVC material has a variety of symbols, and in accordance with the recent trend of wanting to produce a unique prop, there is only a design change of the printed material that is exposed to the outside, but it cannot escape from the limited design. There is a problem that there is a limit in achieving diversification. Accordingly, in recent years, a transparent card made of a plurality of layers of transparent PVC film has been developed.

The present invention has been made to solve the above problems, an object of the present invention is to provide a three-dimensional plastic card having a three-dimensional plastic card and its manufacturing method.

In order to achieve the above object, the three-dimensional plastic card of the present invention is formed in a predetermined size to provide a thickness of the card and a three-dimensional image is printed on the front surface is a plastic sheet attached to the information storage medium, attached to the front of the plastic sheet A lenticular sheet divided into a lenticular region in which semi-cylindrical lenses are arranged and a hologram region that is a flat region, and a holographic foil attached to the flat hologram forming region of the lenticular sheet.

In addition, the method of manufacturing a three-dimensional plastic card of the present invention prints a three-dimensional image on the front surface of the plastic sheet, a data storage medium is attached, the lenticular region and the flat hologram area in which semi-cylindrical lenses are arranged on the front surface of the plastic sheet. Attach a separate lenticular sheet. Subsequently, the hologram foil is attached to the flat hologram area of the lenticular sheet.

In the present invention, it is preferable that the method of attaching the hologram foil uses a hot stamping foil method.

Further, in the present invention, the method of forming the flat holographic region is formed by using a mold of the lenticular lens, or filling the gap between the preformed lenticular lens with a liquid epoxy or UV ink to flatten it, or Heat and pressure may be applied to a predetermined area of the pre-formed lenticular lens to flatten it.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the embodiment of the present invention, a credit card using a magnetic tape as an information storage medium is exemplified. In addition, a smart card or a chip card may be used as the information storage medium.

Lenticular is used as a method of producing and reproducing three-dimensional effects or moving images while maintaining the properties of a photograph. With lenticular, the expression area of the picture is expanded as an interactive image by making multiple images visible as the audience moves.

In the present invention, the three-dimensional card is stereoscopic printing (stereoscopic printing) to make the picture look three-dimensional, it is preferable to make a lenticular lens made of a transparent plastic on the printed image exactly after printing a photograph taken specially.

Lenticular is a long cylindrical lens sheet arranged by the semi-cylindrical lens is arranged to see the sequentially arranged images sequentially. Since each lens enlarges the image of a specific position according to the angle, it is possible to see one of several images by selecting the position of the receiver.

1 and 2 are front and rear views of the three-dimensional plastic card according to the present invention, Figure 3 is an exploded perspective view of the three-dimensional plastic card according to the present invention.

1 to 3, the three-dimensional plastic card is composed of a plastic sheet 10, a lenticular sheet 20, and a hologram foil 40.

The plastic sheet 10 has a plurality of three-dimensional images and the authentication mark 15 is printed on the front, the magnetic tape 45 and the signature unit 50 is attached to the back.

The lenticular sheet 20 attached to the front surface of the plastic sheet 10 is divided into a lenticular lens portion in which the semi-cylindrical lenses 25 are cut long, and a flat hologram region 30 to which the hologram foil 40 is attached. It is. Preferably, in order to clarify the certification mark portion, a flat certification mark area 35 may be further formed.

Hereinafter, a three-dimensional plastic card according to the present invention will be described a manufacturing method.

First, a plurality of images are three-dimensionally printed on the front of the plastic sheet, and a magnetic tape is attached to the back of the plastic sheet.

Subsequently, semi-cylindrical lenses form a lenticular sheet which is divided into a lenticular region arranged and a hologram region which is a flat region. Various methods may be used to form the lenticular region and the hologram region. For example, when making a lenticular sheet, a mold may be formed by dividing the lenticular area and the hologram area, or the gap between semi-cylindrical lenses is filled with a preformed lenticular lens with a flowable epoxy or UV ink. It is possible to form a flat hologram area, or to form a hologram area by applying heat and pressure to a predetermined area of the pre-formed lenticular lens to flatten it.

The plastic sheet then attaches the lenticular sheet to the front surface.

Next, the hologram foil is attached to the hologram area of the lenticular sheet. Unlike the lenticular region, the hologram region may be attached to a flat surface so that the shape of the hologram foil is not deformed, and is easily attached. As a method of attachment, various types of thermal transfer materials are known to obtain a desired shape or decoration. Generally, a thermal transfer layer having a desired shape or pattern is directly formed on a thermal transfer tape or a sheet-shaped medium directly before thermal transfer. .

In the above-described stereoscopic card, a plurality of images can be viewed according to the position of the receiver in one plane.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention made as described above, you can see a number of images with a three-dimensional effect on the front of the plastic card.

In addition, there is no deformation of the hologram foil attached to the front surface of the three-dimensional plastic card, there is also an advantage that easy attachment.
