LentICULA CARD, METHOD FOR PRODUCING THE CARD, LENS PALATE FOR PRODUCING THE CARD AND USE OF THE CARD lenticular card, method of manufacturing the card, lens plate for manufacturing the card, and method of using the card as a financial transaction card AS A CARD FOR FINANCIAL TRANSACTION}

The present invention relates to a card having a lenticular layer and a method of manufacturing the card, and more particularly, to a lenticular card including a lenticular layer formed by directly thermocompressing a surface of a card without using a lens sheet having a lenticular layer. A method of manufacturing a lenticular card, a method of using the lenticular card as a financial transaction card, and a plate for manufacturing the lenticular card.

Displaying advertising text and increasing the market value of products by adding images of sports figures, movies and TV characters and other graphics, throughout recent industrial products, including conventional plastic molded cups, containers, billboards, etc. The practice of letting is increasing. Although the printing process of creating these messages, images and graphics has improved with advances in printing technology in recent years, messages, characters and other graphics have generally remained two-dimensional, static and motionless. The expectations of buyers of these products continue to rise, and the general public continues to demand that visual effects be improved and enhanced in all media.

The use of lenticular lens sheets to provide products with more visually appealing images and graphics in response to these consumer demands significantly improves the visual effects of the product by including 3D moving images. The production of such lenticular lens sheets is known and described in detail in a number of US patents, including US Pat. No. 5,967,032 (Bravenec et al.).

Generally, the lenticular lens sheet is used for stereoscopic photo printing, moving picture animation printing, and stereoscopic image representation, which make a planar image look perspective and stereoscopically. This is a set of fine lenses with, and when placed side by side in parallel, it appears as if an object is floating in space on a plate on which two types of objects visible from both the left and right eyes are printed with multiple lines. In addition, when two kinds of images are combined at a normal viewing distance, the first object can be seen closer. Further, by moving the position of the slightly different objects that can be seen when moving the left and right eyes in the same way in response to the movement of the eyes and recording the images according to them, a more realistic three-dimensional feeling can be obtained. In addition, if a moving object is made into a stationary image at each moment and printed and recorded sequentially, a moving picture can be seen as the eyes move from side to side.

The general production process of the lenticular lens sheet involves selecting a segment from a visual image to produce the desired visual effect and interlacing the segment (i.e., planning the layout of several images). ] Is included. Next, the lenticular lens is mapped to the interlaced segment, that is, the planned segment, and a lenticular lens sheet is produced according to this mapping. Lenticular lens sheets generally comprise a transparent web having a flat surface or layer and a groove formed by the convex lens and a surface provided with an optical ridge, which is disposed side by side with the lenticular or the optical ridge of the transparent web. Extend parallel to each other along the length. To provide a unique visual effect, ink (eg, four-color ink) is applied or printed directly on the flat side of the transparent web to form a thin layer of ink, which can be seen through the transparent web of optical ridges.

The field using such lenticular lens sheet is widely known in the printing industry for producing advertising materials as applied to a promotional advertising card, as disclosed in Korean Utility Model Publication No. 1999-11953. It is used for etc.

In addition, Korean Utility Model Application No. 2002-0028435 discloses a multi-function card in which a display layer including a name, a resident registration number, a photograph, a company, a job title, a telephone number, a design, and the like on the front of the card is described. A multifunctional composite card including a lenticular layer for expressing a three-dimensional impression, a magnet layer on which the card holder's driver's license number, a social security number or a bank transaction password is treated with a predetermined magnetic material, and a glossy coating layer are disclosed. We wanted to apply a lenticular lens sheet to a trading card. However, the above invention uses a method of attaching the lens sheet on which the lenticular layer is formed to a desired area using an adhesive, and thus the adhesive part is easily peeled off. There was a lot of problems to be used as a card for financial transactions because it cannot be thermally compressed.

In more detail, the manufacturing method of the conventional lenticular card, as shown in FIG. 1, is first rolled with a lens roller (roller 10), in which a lens groove is processed, to a material such as PET, PP, acrylic, or PVC. After manufacturing the prepared lens sheet 11, and cut the lens-molded sheet to any size to print the desired design on the back of the lens sheet is not formed of the lens waveform, and using a print protection coating agent to protect the printing surface After the coating layer 13 is formed or the adhesive layer 14 is formed, the protective sheet of the same material as the lens sheet 11 is adhered to, and it can be seen that the card is completed through processing such as punching.

Referring to Figure 2 it can be seen that the effect of the printing surface of the lenticular card 100 manufactured according to the manufacturing method of the conventional lenticular card described above using a lens sheet having a lenticular layer in contrast to the printing surface of a conventional card have. In order to use the lenticular card 100 for financial transactions, an anti-counterfeiting printing unit 102 is formed and a hologram 101 is attached to the lens sheet. However, the lens sheet is attached on the printing unit 102 and the identification of the printing unit 102 is impossible due to the image distortion due to the lenticular waveform, and the hologram 101 necessary for the financial transaction card is thermally compressed through the card. It should be attached to the hologram 101 can be seen that it is impossible to attach the hologram 101 on the lenticular surface because the transfer of the hologram 101 is impossible due to the bending of the lens waveform.

Such a card having a lenticular layer has a low strength without restoring delamination and warpage caused by gluing a lens sheet having a lenticular layer with an adhesive, a holographic transfer impossibility on the top of the lenticular surface, and an anti-counterfeiting printing portion. Due to many problems such as unrecognizable, it was not suitable for being used as a financial transaction card.

Therefore, there have been a number of demands in the art for a lenticular card that can be used for financial transactions by solving the problems of the conventional lenticular card.

In order to solve the above problems, the present invention is a lenticular card and the lenticular card by directly pressing the surface of the card to form a lenticular layer by using a lens plate formed with a lens waveform without using a lens sheet on which a lenticular layer is formed. An object of the present invention is to provide a manufacturing method.

Another object of the present invention is to provide a lenticular card having a lenticular layer including a lenticular region having a lens waveform and a non-stereoscopic region having no lens waveform, and a method of manufacturing the lenticular card.

Another object of the present invention is to provide a method of using a lenticular card as a financial transaction card.

It is another object of the present invention to provide a plate for manufacturing a lenticular card capable of directly forming a lenticular layer through thermocompression bonding to a card surface.

Referring to FIG. 3, a card sheet 200 (not shown in the drawing, but the back of the card sheet 200 may be provided with a printed layer on which a design to be printed may be formed) may be prepared. The lens plate 300 having the lens waveform formed thereon is disposed on the 200, and the lens plate 300 is directly thermocompressed to the surface of the card sheet 200 to form a lenticular layer. At this time, if the card sheet 200 is a synthetic resin containing PP, PE, acrylic, PVC, etc., 20 ~ 30 minutes at a pressure of 10 ~ 30 kgf / ㎠ at a temperature of 110 ~ 160 ?? 20 ~ again It is preferable to perform the thermocompression process of cooling for 30 minutes in one to three times. On the other hand, if the material of the card sheet 200 is a material other than the synthetic resin, for example, in the case of a metal can be set to a condition suitable for the conditions of the material of the metal to perform a thermocompression process. Thereafter, the lens plate 300 may be separated from the card sheet 200 to complete the card sheet 200 having the lenticular layer formed thereon.

In some cases, the card sheet 200 may be composed of one or more laminated sheets. For example, when the card sheet 200 has three laminated sheets [a printing layer on which one or more of the laminated sheets is printed is printed. Although the description thereof will be described later], the lower lamination sheet 230, the intermediate lamination sheet 220, and the lens sheet 210 in which the lenticular layer is formed are preferably sequentially stacked. As described above, when the card sheet 200 is formed of at least one laminated sheet, the lamination process and the lenticular layer forming process may be simultaneously performed.

That is, in the conventional lamination process, since the at least one sheet is laminated and disposed between two plates, that is, the upper plate and the lower plate, and the upper plate and the lower plate are thermocompressed, the card sheet 200 is at least one laminated sheet. More specifically, in the case of three laminated sheets, the lower laminated sheet 230, the intermediate laminated sheet 220, and the lens sheet 210 on which the lenticular layer is formed are sequentially disposed on the lower plate, and then the lens is disposed. This is because the lens plate 300 having the lens waveform formed between the sheet 210 and the upper plate may be disposed such that the surface on which the lens waveform is formed faces the lens sheet 210 and then perform a thermocompression bonding process.

Although not shown in the drawings, a low frequency circuit or a high frequency circuit including an antenna coil may be embedded in any one of the laminated sheets, respectively, or in combination, and an integrated circuit chip may also be embedded in any one of the laminated sheets. One of the laminated sheets may be an inlay sheet fabricated to include an antenna coil or an integrated circuit chip. Meanwhile, the integrated circuit may be embedded through the pocket milling process after completing the card sheet 200.

It can be seen that it is attached. That is, when the printing unit 102 is formed in the non-stereo area 212 and the hologram 101 is attached, image distortion due to the lenticular waveform does not occur, so that identification of the printing unit 102 is not disturbed at all. This is because the hologram 101, which is necessary for a financial transaction card, can also be easily transferred to the card through thermocompression without interference due to the bending of the lens waveform.

Although not shown in FIG. 4, the lenticular card 100 for financial transactions according to the present invention may further include other components required for financial transactions, such as a magnetic stripe or an embossed card number.
