Description

Anti-counterfeiting changing device containing retro-reflective material

Technical Field

The invention relates to an anti-counterfeiting modification device containing a retro-reflective material, in particular to an anti-counterfeiting modification device containing a retro-reflective material, which comprises a plurality of layers, wherein the plurality of layers comprise the retro-reflective layer, and the anti-counterfeiting modification device contains the retro-reflective material for irradiating light to the plurality of layers comprising the retro-reflective layer to distinguish whether the anti-counterfeiting modification device is false or not.

Background

Various techniques have been described for preventing the counterfeiting and alteration of goods to ensure the authenticity of high-priced goods or contents. At present, technologies such as micro-patterns, braille, holograms, RF IDs, etc. are mainly used for preventing the forgery and alteration of goods, but these prior arts have a problem in that it is not easy for a general user to identify the forgery and alteration of goods using this technology or the cost required for manufacturing the forgery and alteration preventing apparatus is large.

Various methods have been proposed to fundamentally solve the problems of the existing anti-counterfeiting modification devices, but a method of applying materials using a retro-reflection principle has been suggested.

Retro-reflection refers to the reflection of an incident ray back to the light source. That is, when light emitted from an object (light source) reaches another object, the light reaches the object, i.e., the light is reflected back to the light source. In short, light emitted from an object reaches some object and then returns to the original position.

At this time, the light reflects in the direction of the light source regardless of the angle from which the light is irradiated on the object. As is common in road signs, when a road sign is illuminated by light emitted from a head lamp of a vehicle traveling at night, the road sign is lit at the eyes of a driver of the vehicle. This is because the light from the headlamps, after reaching the surface of the reflective product, i.e., the road sign, is re-reflected back to the light source by retro-reflection.

By applying the principle of the retro-reflection, most of road signs with large turning or road construction signs at night use retro-reflection products so as to easily identify objects at night.

The QR code is a matrix two-dimensional barcode that displays information in a black and white check pattern. The common bar code can only store numbers or characters in a single direction, and compared with the common bar code, the QR code can store data with larger capacity, so that the bar code is widely applied to various fields.

Generally, a QR code is obtained by capturing an image with a camera or other device having a reader provided on a smart phone and reading data. That is, the user can read the data in the QR code by anyone as long as he has a device that can read the standard QR code.

According to the patent and utility model documents of the anti-counterfeiting changing device aspect applying the material by the regression reflection principle, KR patent application No. 10-2011-0006868 (title of the invention: anti-counterfeiting changing adhesive seal and manufacturing method thereof) discloses an anti-counterfeiting changing adhesive seal which is a seal in which a holographic layer capable of playing an image by incident light, a regression reflection material layer for returning the incident light to an incident light entering method, and an adhesive layer for adhering an article are laminated, wherein the holographic layer is a rainbow hologram layer capable of playing 2D and 3D images when white light is irradiated from a specific direction at a specific angle, and the rainbow hologram image disappears and a new fourier transform hologram can be played when laser is irradiated from a specific direction at a specific angle, and the regression reflection material layer is composed of an interference material layer of mica powder for causing a colored interference color and transparent microspheres arranged on the rainbow.

However, the above-mentioned forgery-preventing altered adhesive seal has an advantage that it is difficult to forge and alter printed matter, but has a disadvantage that the manufacturing cost of the adhesive seal is too high.

Disclosure of Invention

Technical problem

The present inventors have made extensive efforts to develop a forgery prevention device that is not easily distorted and is easily manufactured, and as a result, they have found that a QR code can be manufactured using a retro-reflective material that exhibits other colors when irradiated with light emitted from a mobile phone or the like, and the QR code can be recognized in an on state of the illumination to confirm whether or not the QR code is distorted, and whether or not the QR code is distorted can be confirmed more accurately through these processes, and the manufacturing is very simple, and thus the present invention has been completed.

It is therefore an object of the present invention to provide a tamper-resistant tamper device including a retro-reflective material.

Another object of the present invention is to provide a QR code for forgery/alteration prevention including a retroreflective material.

Other aspects and advantages of the invention will become apparent from the following summary, the appended claims and the accompanying drawings.

Technical scheme

The invention provides an anti-counterfeiting changing device.

In one aspect, the present invention provides a tamper-resistant device comprising a retro-reflective material, the device comprising a plurality of layers, the plurality of layers including a retro-reflective layer, wherein illumination of the plurality of layers including the retro-reflective layer distinguishes between tampering and tampering.

The term "retro-reflection" used in the present specification refers to reflection in which incident light is directly returned to a light source.

In the wording used in the present specification, the term "pseudo alteration" means that an unauthorized person performs, for his or her own purpose, an action of making an article that does not exist at present or an action of making an unauthorized modification of an article that exists at present.

The term "computer" as used herein refers to a machine that processes various data using electronic circuits.

The term QR code as used herein refers to a two-dimensional (matrix) code in which various information is loaded in various combinations of circular or rectangular dots in various forms and a pattern is printed.

According to a preferred embodiment of the invention, the plurality of layers of the invention comprising a retro-reflective layer is preferably, comprising: a synthetic resin film layer; a first adhesive layer located on the synthetic resin film layer and bonding the layers located on the synthetic resin film layer; a reflective layer on the first adhesive layer; a color development layer positioned on the upper part of the reflecting layer; a second adhesive layer which is positioned on the upper part of the color development layer and bonds the layers positioned on the upper part of the color development layer; and a retro-reflective layer on the second adhesive layer.

According to a preferred embodiment of the present invention, on the color developing layer of the present invention, preferably, a symbol, a character, a figure, or a combination thereof, which can identify whether or not a forgery or a change is possible, may be printed.

In the invention, the color development layer is printed with symbols, characters, figures or structures which are very important and can identify counterfeiting or alteration. Since a pattern or the like which can be recognized as a forgery or alteration is formed on the color developing layer, it cannot be seen in a state without light irradiation, but can be recognized only in a state with light irradiation, it is possible to recognize whether or not a forgery or alteration is made more accurately.

A part of the light irradiated to the retro-reflective layer is reflected back along the irradiation path, and the remaining part is reflected from the retro-reflective layer by irradiating the color developing layer and the reflective layer, so that the symbol, the character, the graphic, or the combination thereof, etc. printed on the color developing layer can be recognized from the outside.

Further specifically, the sizes of the plurality of refractive bodies constituting the retro-reflective layer are different from each other or the arrangement structure may be uneven, and thus the remaining part of the irradiated light may reach the color-developing layer and the reflective layer.

That is, the retro-reflective layer is formed by coating glass beads on the surface of a film or attaching a film in the form of micro prisms, and light incident on the refractors, i.e., the glass beads or the micro prisms, is sequentially refracted in the prisms, and is returned as light parallel to the light source.

In this case, if the size of glass beads or the size and arrangement of microprisms coated on the film are uniform, retroreflection occurs by 100%.

Therefore, according to an embodiment of the present invention, the retro-reflective layer may be composed of glass beads coated in various sizes, or micro prisms configured or sized differently so that the remaining part of the light irradiated to the retro-reflective layer reaches the color developing layer and the reflective layer.

According to a preferred embodiment of the invention, said symbols, letters, graphics or a combination thereof of the invention are printed on a black ground colour.

The printing of the symbols, text, graphics or combinations of these on a black background is a very important structure in the present invention. Since the symbols, characters, figures, or a combination thereof are printed on the black ground, a pattern or the like in which whether or not the false alteration is identifiable cannot be identified in a state where the illumination is off, and a pattern or the like in which whether or not the false alteration is identifiable can be identified only in a state where the illumination is on.

According to a preferred embodiment of the invention, the color-developing layer of the invention preferably has a first QR code pattern on printed symbols, text, graphics or combinations thereof for identifying forgery or alteration.

In the invention, the first QR code pattern is an important structure of the symbols, characters, figures or the combination of the symbols, the characters and the figures which are printed on the color development layer for identifying whether the color development layer is forged or altered. Because the QR code pattern is printed on the color development layer for identifying whether the color development layer is forged or altered, the color development layer can not be seen in a non-light-irradiation state, and can be identified only in a light-irradiation state, thereby more accurately identifying whether the color development layer is forged or altered.

According to a preferred embodiment of the present invention, the black matrix of the present invention is preferably a second QR code pattern.

The black background color of the present invention is a very important structure for the second QR code pattern. Because the black background color is a second QR code pattern, whether the false change exists or not can be judged by identifying the QR code under the condition that the illumination is closed.

According to a preferred embodiment of the present invention, the first QR code pattern and the second QR code pattern of the present invention are, preferably, the same or similar.

According to a preferred embodiment of the present invention, the first QR code pattern of the present invention is preferably recognized only in a state where light is irradiated.

According to a preferred embodiment of the present invention, the first QR code pattern of the present invention is similar to the second QR code pattern, and after the second QR code is recognized, the first QR code is recognized in a state of being irradiated with light, thereby recognizing whether or not it is forged or altered.

In the invention, the first QR code pattern is similar to the second QR code pattern, and after the second QR code is identified, the first QR code is identified under the light irradiation state, so that whether the QR code is forged or altered is very important. Since the first QR code pattern is printed on the second QR code pattern, and the second QR code pattern is printed in a similar pattern to the first QR code pattern, the QR code pattern recognized in a non-light-irradiated state is different from the QR code pattern recognized in a light-irradiated state, and thus it is not only difficult to falsely change, but also it is possible to more precisely confirm whether or not the falsely change is made.

According to a preferred embodiment of the present invention, the pattern formed by the first QR code and the pattern formed by the second QR code are 80 to 99.9% identical, and the remaining 0.1 to 20% may be formed differently.

According to a more preferred embodiment of the present invention, the pattern formed by the first QR code and the pattern formed by the second QR code are 90 to 99.9% identical, and the remaining 0.1 to 10% may be formed differently.

According to another embodiment of the present invention, there is provided a method of counterfeit identification using a counterfeit deterrent device comprising a retro-reflective material, comprising the steps of. (a) providing a film layer comprising a synthetic resin; a first adhesive layer which is located on the upper part of the synthetic resin film layer and bonds the layers located on the upper part of the synthetic resin film layer; a reflecting layer on the synthetic resin film layer; a color development layer positioned on the upper part of the synthetic resin film layer; a second adhesive layer which is located on the upper part of the color development layer and bonds the layers located on the upper part of the color development layer; and irradiating light to the anti-counterfeiting modification device of the retro-reflection layer positioned on the upper part of the second bonding layer; (b) A step of visualizing the QR code printed on the forgery prevention alteration device by irradiation of the light; and (c) identifying the QR code visualized by the light with a QR code identification device to determine whether or not the QR code is altered.

The contents of the method for confirming the false alteration of the anti-counterfeiting alteration device comprising the retro-reflective material adopted in the invention are the same as those of the anti-counterfeiting alteration device comprising the retro-reflective material, so the details are not described, and the contents in the specification are not too complicated.

Here, the plurality of patterns may be printed by various methods used in the art, such as screen printing, rotary printing, offset printing, gravure printing, and flexographic printing.

Fig. 2 illustrates a state in which light is irradiated to a general pattern printed on the color developing layer to confirm whether or not the pattern is artificially altered.

According to fig. 2, a specific pattern G is printed on the color developing layer. The state of the pattern printed on the color-developing layer emitting light when irradiated with light can be confirmed. When the lighting is performed, the background colors in fig. 2 are consistent, and G can display different colors.
