Description

[0001] The present invention relates to an anti-counterfeiting printing method using a seegram,

[0001] The present invention relates to a magnetic security element that exhibits a hidden image effect, which is a three-dimensional movement, and a method of printing and a method of preventing forgery. More specifically, the magnetic ink is used to print a specific pattern on a substrate, To form a magnetic induction image by applying a magnetic field with the magnet of the magnetic security element, and then drying and curing the magnetic security element light to realize a stereoscopic moving signal, and to prevent various counterfeit products using this cigarette.

There have been three major anti-counterfeiting technologies. First, the hologram second. Thirdly, micro-lenses were used.

 First, Grams have a complicated pattern that consumers can not easily recognize. In China, for example, there were frequent occurrences such as falsifying holograms of official documents in Korea by abusing them.

Second, RFID needed a separate reader. As a result, it was never easy for consumers to use genuine products.

Finally, the microlenses were protruding from the surface and were susceptible to wear and tear, could be copied, and the pattern was blurred.

In order to overcome the shortcomings of the above-mentioned anti-counterfeiting technology, there is also an increasing prospect of adding security elements to the printed image as a security element for easily checking forgery and preventing copying.

Various types of optically variable devices are used as anti-counterfeiting technologies for these items. Of these, optically variable security devices, which are particularly important, are time-varying inks that change color depending on the angle of view. .

Recently, a magneto-optically variable ink is used that allows magnetically induced images, designs and patterns to be generated through the application of a magnetic field in printing ink or coating as a way to maximize this optically variable effect. These magnetically optically variable inks are known to have a three-dimensional, relief-like appearance of the magnetically induced design or pattern by allowing the coding to dry after the magnetopically tunable pigment is incubated in the coating.

Accordingly, the present inventors have tried to solve the above problems by printing a specific pattern in which a printing area and a non-printing area intersect with each other by using magnetic ink, and applying a magnetic field with various kinds of magnets, And then completed the present invention.

The present invention has been proposed in order to solve the above-mentioned problems of the previously proposed methods, and it is a goal to prevent counterfeit goods that are frequently circulated today. If counterfeit goods become popular, the enthusiasm for the development of the company's own trademarks and products will shrink, which may hinder domestic industry development.

 In order to make a brand worth having a certain amount of money, it is necessary to invest a lot of advertising costs and products. Unauthorized exploitation of trademark values without much effort is not merely the economic interests of the trademark owner, but it is also an act of disrupting business credibility, disturbing fair trade, and infringing on the interests of consumers. Therefore, counterfeiting products should be prevented.

  Today's holograms are difficult to distinguish genuine because of their complexity. However, the use of a cigram makes it easy to distinguish genuine and counterfeit goods. By attaching a unique cigarette sticker, which stands for each company, to the produced product, consumers can easily distinguish the genuine products of the company anytime and anywhere. In order to achieve the above object, the present invention can improve the reliability of a product for a product, prevent counterfeiting, and perform it safely and contribute to customer satisfaction. In order to provide a magnetic security element showing the image effect of moving in a three-dimensional manner, a specific pattern is printed using a magnetic ink on a base material, a magnetic field is applied by various magnets to orient a desired image, The magnetic security element formed by the magnetic security element and the printing method thereof are used to enhance anti-counterfeiting.

 In order to prevent the above problems, the following devices have been devised and widely used to prevent counterfeit goods more efficiently.

 This ensures that the product is genuine by using the seedgram and that it is different from the counterfeit product. It also prevents counterfeiting and similar selling of packaging after the export of the product. When a scanned copy is scanned, the original image of the scanned image is damaged and is not easy to handle. According to an aspect of the present invention, there is provided a transfer material comprising a three-dimensional lens sheet including a plurality of nanostructures,

 An adhesive layer formed on the image-forming layer or the light-shielding layer of the three-dimensional lens sheet, and a release film formed on the three-dimensional lens layer of the three-dimensional lens sheet. In order to achieve the object of the present invention, a pattern in which a printing region and a non-printing region of a magnetic ink cross each other is printed on a surface of a substrate, and when a magnetic field is applied to a substrate on which the pattern is printed, The present invention also provides a magnetic security element that exhibits a hidden image effect. In addition, the present invention provides a magnetic security element which is used for printing a pattern in which a printing area and a non- Wherein the magnetic induction image is formed by applying a magnetic field with a magnet to form a magnetic induction image, There is provided a method for printing a magnetic security element that represents a stereoscopic moving the hidden image effect, comprising the step of drying.

First, consumers can identify genuine products anytime and anywhere by attaching a cigram sticker to a product exported by a company.

Second, the holograms used today are difficult to distinguish from genuine ones because they are complicated in appearance, but if you use a cigram, you can easily distinguish it without special tools. . It also provides a stereoscopic moving image effect that can not be implemented by copying, and is thus particularly useful for preventing forgery modulation. In order to achieve the above object, the present invention is expected to use the cigram to secure the reliability and the counterfeiting of the consumer as safely as possible and contribute to customer satisfaction.

1 and 2 are diagrams based on a cigram effect.
Fig. 3 is a diagram showing a cigarette attached to a product to be sold.

The features and advantages of the present invention will become more apparent from the following detailed description based on the drawings. Fig. 3 is a view showing a cigarette attached to a product to be sold. For convenience of explanation, the same reference numerals are used for the same parts as those of the conventional configuration.

Looking at the outer surface of the merchandise, the cigram is attached to the bottom left corner and it is made of a transparent protective film to reduce the damage of the cigram.

It is structured so that consumers can easily and easily check the validity of the product when it is needed,

In addition, the stereoscopic moving cigram image is expressed by the pattern printing, the magnet of various shapes and the intensity of the magnetic field, and can be confirmed by tilting and rotating, and the cigram means the dynamic effect , Which means that the image is displayed according to the viewing angle, and is a security element for preventing counterfeiting by making copying impossible.

In the present invention, a silk screen technique is used to print a pattern, but the present invention is not limited thereto, and other methods of applying ink can be used. That is, conventional methods known as Libyan ink, flat printing, flexographic printing, letterpress printing, ureter printing, or applying ink may be used. However, ink of different areas may be applied, It is only required to be done. The silk screen size of the designed fine line pattern can be 150 or 250 mesh. As the number of meshes increases, the thickness of the ink decreases. Therefore, 150 mesh is suitable.

In the present invention, in order to confirm the effect of the stereoscopic moving pattern according to the print pattern, the number of fine lines was set to 1 to 2 mm and the intervals between the lines were varied to 0.3 mm, 0.6 mm, 08 mm, 1.5 mm, As the width increases, the effect of the stereoscopic movementgram is better as the distance between the thin lines decreases. Also, when the thin line width is larger than the interval between the three lines, a stereoscopic moving gram effect is obtained. The effect of stereoscopic cogram was excellent at 0.5 ~ 1.5, and the effect of stereoscopic cogram was even better when the ratio was 0.1 ~ 0.35.

Further, the effect of the brightness ratio of the non-printing area on the brightness of the printing area was confirmed. The stereoscopic movement effect was not related to the brightness value, but the ratio of the brightness of the non-printing area to the brightness of the printing area is required to be 1.3 to 100 in order to implement the cigram.

In the present invention, an opaque substrate such as paper, foil or polypropylene used as a base for printing magnetic ink, or a transparent film substrate such as polyvinyl chloride, polycarbonate, or polyethylene terephthalide may be used.

The magnetic ink used for screen printing can be used in both UV curable inks and solvent evaporative inks, and the alignable flake pigment upon application of a magnetic field can change the position of the observer or the position of the light source, Pigment is used.

This seed has a great impact on the industry today.

It is used to protect brand, and can prevent the forgery of clothing, logo label, electric appliances, admission ticket, golf goods, record, video, food, liquor,

Also, it can prevent counterfeit such as passport, ID card, driver's license, employee's ID card, pass badge used for ID card. Finally, counterfeiting of bills, credit / department store cards, gift certificates, certificates, etc. used for securities and public goods can be prevented.
