Description

Method for manufacturing anti-counterfeiting gold foil prints marked with QR code and gold foil prints manufactured by the method}

The present invention relates to a method of manufacturing a gold foil printed material for anti-counterfeiting with a QR code displayed, and a gold leaf printed product manufactured by the method thereof, and more particularly, a QR code that can receive various information by scanning a QR code with a smartphone in order to more reliably prevent counterfeiting. It relates to a method of manufacturing a printing plate for anti-counterfeiting using a metal (thin film) layer patterned with a code, and a gold foil printed product in which a QR code manufactured by the method is patterned.

In general, a QR code [Quick Response Code] is a grid patterned two-dimensional code that can contain much more information than a barcode, and is a two-dimensional grid code displayed on a product paper, advertisement, or display surface for advertising and promotion for displaying product information. In general, by scanning a QR code with a smartphone, various information can be provided. This is a two-dimensional (matrix) code that contains various information in a square horizontal and vertical grid pattern, and'QR' is an acronym for'Quick Response'. It was developed by Denso Wave in Japan in 1994, and it is widely used in various fields as Denso Wave declared that it would not exercise its patent right.

While conventional 1-dimensional barcodes can only store numeric information of around 20 characters, QR codes can store up to 7,089 numbers, up to 4,296 characters (ASCII), up to 2,953 bytes in binary (8 bits), and up to 1,817 Chinese characters. It has better recognition speed, recognition rate, and resilience than general barcodes. If barcodes are mainly used for calculation, inventory management, product verification, etc., QR codes are often used as a means of marketing, promotion, and PR. In addition, a dedicated terminal that can read existing barcodes was only owned by product sellers, so it was impossible for consumers to grasp information using barcodes, but in the case of QR codes, consumers can directly grasp product information with a smartphone. The use of QR codes has increased with the spread of smartphones. Smartphone users can easily obtain various information by downloading the free QR code scanning application and then scanning the QR code posted on billboards, promotional papers, posters, magazines, and the Internet with their smartphones.

QR code information is provided both offline and online. For example, if you hold your smartphone over the QR code of a parent product in a paper magazine, you can connect to the product's website to obtain various product information, event information, coupon benefits, etc., and sports events. B. If you scan the QR code of a movie poster, you can receive promotional video and photo information, discount ticket and admission ticket information, and movie theater or stadium information.

Banks, credit card companies, airlines, etc. can provide payment services using QR cards, and retailers such as department stores and discount marts use flyers, newspaper advertisements, and QR codes posted on the website instead of discount coupons delivered to home. In addition to discount coupons, event items and promotions can be provided. There are so many tombstone companies that have launched models that can engrave a QR code on a tombstone to view a picture of the deceased or a record of a lifetime.

Also, anyone can create their own QR code by using the QR code creation site. In other words, individual business owners or those who want to promote something can introduce themselves by attaching a unique QR code to their business card, and can promote what they want to announce by inserting it into a blog, twitter or offline flyer.

Information or display of a product printed on a three-dimensional multi-layered anti-counterfeiting printing plate made of a metal layer that has been plated and multiplied by using such a QR code in the form of a hologram or laser etching that is designed to prevent counterfeiting. It is to prevent counterfeiting of products and provide information on products by manufacturing thin metal paper (product package) and stickers in which QR codes are inserted in the pattern.

Conventional hologram paper or sticker is used to prevent counterfeiting of cards, expensive liquor, cosmetics, etc. as marking on products that can be mass-produced once manufactured. However, recent products are being produced in a large number of small quantities, and as such multi-kind products are released, technologies for displaying information or preventing counterfeiting of products have been diversified. One of these technologies is the anti-counterfeiting technology that makes it difficult to duplicate or imitate products, such as multidimensional designs in the form of holograms, or 3D/multidimensionally plated metal etching printing plates or lasers that make copying and imitation difficult. It is classified as a technology that manufactures and attaches or displays metal thin-film paper/packages or stickers printed with an etched printing plate.

However, this anti-counterfeiting technology may correspond to a technology that simply prevents counterfeiting, not a display technology that can contain product information. Therefore, the inventor of the present invention uses a two-dimensional flat grid pattern code to scan with a smartphone, etc. to provide more information and to provide a double anti-counterfeiting technology more reliably to prevent counterfeiting. It was intended to be further added to the technology of manufacturing a metal thin film paper/package or sticker printed with a printing plate or a laser etching printing plate.

However, these conventional two-dimensional flat grid pattern codes and QR codes are designed and inserted into a metal thin film with a plated-proliferated metal etching printing plate, and the metal thin film is scanned as it is with a smartphone to read the information, and the information of a small and sophisticated QR code is recognized. There is a disadvantage in that the information of the QR code is not recognized exactly as a method. In order to solve this problem, the present inventors design and insert the QR code into the "anti-counterfeiting printing plate using a plated-proliferated metal layer" of his conventional registered patent (Korean Registered Patent No. 10-1845205). Even if the multi-layered structure (dots/lines, etc.) is scanned, it is now possible to find out what information in the QR code is recognized.

However, if the information is read by scanning with a smartphone, etc., if the QR code is patterned and inserted into the metal thin film surface layer, the light is bright and the location where it is illuminated even if it is printed in a three-dimensional multi-layered structure (dots/lines, etc.). There is a phenomenon in which light is scattered or distorted by the light, so that the information of the QR code is often not recognized.

As a technology related to a QR code according to the prior art, a'design QR code production method' has been proposed through Korean Patent Registration No. 10-1260499, and the claim 1 has'three position detection patterns, and the position detection A square QR code layer composed of a plurality of cells patterned in black and white is generated so that version information and format information are included between patterns, and the QR code layer is an error recovery level of any one of the error recovery levels of the 4 steps. The QR code layer generation step is set to, and a color frame layer of the same size is generated to correspond to the generated position detection pattern of the QR code layer and a plurality of cells, and the color along with each color of the position detection pattern of the color frame layer The color frame layer generation step of selecting the color and shape of each cell of the frame layer, and the QR code layer and the color frame layer are matched to change the position detection pattern of the QR code layer to the position detection pattern of the color frame layer, and the QR code layer A color QR code layer generation step of generating a color QR code layer by leaving only the cell dots by using a cell of the color frame layer corresponding to a black cell among the plurality of patterned cells of In the image generation step, the foreground image is matched with the upper surface of the color QR code layer so as not to interfere with the generated position detection pattern of the color QR code layer, but the color QR code layer is within the range of the set error correction level. Disclosed is a method for producing a design QR code comprising a foreground image matching step of moving the foreground image so that the cell dot is covered by the foreground image.'

However, the anti-counterfeiting technology using a QR code according to the prior art is provided for the purpose of simply preventing counterfeiting, and thus there is a disadvantage that it cannot be used for displaying information of a product or enhancing the beauty of a product or wrapping paper that is an attachment object.

In order to solve these problems, the applicant of the present invention has disclosed in Korean Patent Registration No. 10-1845205,'A method of manufacturing a printing plate for anti-counterfeiting using a metal layer that has been subjected to secondary plating growth by exposure technology, and a method of manufacturing a metal thin film for anti-counterfeiting using a printing plate for anti-counterfeiting. A metal thin film for anti-counterfeiting has been proposed, and claim 1 includes a step of preparing a transparent film on which a micro pattern is developed; Applying a photoresist to the surface of the micro-polished stainless steel plate and drying to form a photosensitive coating layer; A step in which the transparent film on which the micro-pattern is developed is in close contact with the photosensitive coating layer, exposed to ultraviolet light, and cured; Removing the transparent film on which the micro-pattern is developed, and removing portions of the photosensitive coating layer other than the portion exposed to the ultraviolet rays and cured in a negative form; Forming a convex primary plating growth metal layer between portions exposed to the ultraviolet light and cured; Forming a chromate layer for releasing treatment on the surface of the first plating growth metal layer; And forming a second plating growth metal layer on the first plating growth metal layer on which the chromate layer is formed so that a convex portion is formed on the exposed and cured portion of the ultraviolet ray. A method of manufacturing a printing plate for anti-counterfeiting using a metal layer.'

However, manufactured by the'anti-counterfeiting printing plate manufacturing method using a metal layer that has been subjected to secondary plating by exposure technology and a method of manufacturing a counterfeit metal thin film using a counterfeit printing plate and the anti-counterfeiting metal thin film produced by the present applicant'. The metal thin film can implement a recognition code that requires high precision, such as a QR code to prevent counterfeiting, but if such a recognition code is formed in an uneven shape on an ultra-high gloss reflective surface, the shooting angle of a recognition code reader such as a smartphone Accordingly, there is a problem in that the reading rate is lowered due to diffuse reflection.

That is, since the prior art forms an ultra-high gloss reflective surface in the shape of an uneven shape consisting of protrusions and grooves, diffuse reflection is easily generated depending on the location of the camera for photographing it and the surrounding illuminance or illumination, and as a result, diffuse reflection occurs. There was an inconvenience of having to be careful not to shoot.

Accordingly, there is a demand for a technology capable of easily authenticating a subject anytime, anywhere, regardless of photographing conditions.

Referring to the drawings above, a description will be given of a method of manufacturing a gold foil print for anti-counterfeiting with a QR code according to the present invention.

The present invention is a method of manufacturing a counterfeit printing plate using a metal layer that has been subjected to secondary plating by exposure technology in Registration Patent No. 10-1845205 previously applied and registered by the present applicant, and a method of manufacturing a metal thin film for anti-counterfeiting using a printing plate for anti-counterfeiting, and manufactured thereby When the QR code is printed using the technology of'anti-counterfeiting metal thin film', the QR code area can produce a beautiful image due to the diffuse reflection caused by the protrusions and grooves. Abuse occurred. The applicant of the present invention proposes a technique of applying a paint so as to suppress the occurrence of diffuse reflection on the QR code area as follows in order to suppress the diffuse reflection on the QR code area and increase the reading rate during image capture.

First, in the present invention, a transparent film on which a micropattern is developed is closely adhered to a photosensitive coating layer coated on a stainless steel surface and exposed to ultraviolet rays, and an uncured portion of the photosensitive coating layer from which the transparent film is removed is removed in a negative form. With steps. Forming a first plating growth metal layer between the portions exposed to the ultraviolet light and curing, and forming a chromate layer for release treatment on the surface of the first plating growth metal layer. Finally, on the portion exposed to the ultraviolet light and cured A metal thin film manufacturing method consisting of forming a second plating growth metal layer on the first plating growth metal layer on which the chromate layer is formed so as to form a convex portion is used, and since this technique is performed by a known technique, detailed description Is omitted.

The present invention is carried out including the step of manufacturing a printing plate having a metal layer in which the QR code is plated and multiplied as a result of forming a QR code on a partial surface of the printing plate using the secondary plating growth metal layer in the convex portion.

In addition, in the step of preparing gold foil printing of a printing plate for anti-counterfeiting using the metal layer on which the QR code is plated and proliferated, the following process is performed.

1) A reference marker display process is performed in which a reference marker that matches the QR code of the metal layer on which the QR code has been plated-proliferated is displayed on the paper to be attached.

2) When the displayed reference marker is correctly set, a step of coating and coating a resin material that suppresses the diffuse reflection of the QR code to enable identification is applied to the set QR code location.

3) A step of drying the paint-coated paper with a print dryer is performed.

4) Preparing a gold foil printed material of a printing plate for anti-counterfeiting consisting of a printing plate setting step in order to match the dried paint-coated paper with a printing plate of a metal layer copper plate containing a metal layer in which the QR code is plated and proliferated in a gold foil printing machine, and the QR code is plated and multiplied. It is completed by checking the QR code matching on the printing plate of the metal layer copper plate containing the metal layer, and manufacturing a counterfeit metal printed material using the metal layer on which the QR code is plated and propagated in a gold foil printing machine.

Here, the paint may be applied to the entire metal layer, but it is preferable that the coating is limitedly applied only to the QR code area.

In addition, the secondary plating propagation by an exposure technique including the step of forming a secondary plating propagation metal layer on the first plating propagation metal layer on which the chromate layer is formed so that convex portions are formed on the exposed and cured portion of the ultraviolet light. In the method of manufacturing an anti-counterfeiting printing plate using a metal layer, wherein a QR code is additionally formed on a convex portion on a part of the anti-counterfeiting printing plate using the second-plated metal layer. In the printing plate manufacturing step, the step of separating the secondary plating growth metal layer on which the convex portion on which the QR code is plated and spreading is formed, and bonding it to the copper plate may be performed.

Accordingly, the present invention reduces the recognition reading rate due to diffuse reflection when the QR code is imaged using a camera module mounted on a smartphone, as the QR code is coated with a paint such as a varnish on the patterned metal (thin film) layer. Since it can be prevented, it is possible to prevent counterfeiting of goods by allowing more sophisticated QR codes to be read.

On the other hand, when the coating material such as varnish used in the present invention is coated on paper of a specified standard and then the metal layer on which the QR code is plated and multiplied by a gold foil printer is printed, the QR code is more clearly recognized (scanned). It is a transparent paint used to clarify counterfeiting prevention by confirming product information. Of course, a counterfeit prevention function is possible with the precise anti-counterfeiting technology of multi-dimensional etching even with the metal printed material of the conventionally plated etched metal copper plate, but it is now possible to easily check the counterfeit protection with electronic terminals such as mobile phones and smartphones. The technology for preventing counterfeiting of the precise technical plating etching of the present invention is improved.

However, since the QR code is etched very finely and the scanning technology that recognizes the QR code requires very precise recognition, and the metal foil printing reflects or scatters light due to the three-dimensional etching pattern, the image is captured due to the diffuse reflection phenomenon. Due to this inaccuracy, there is a disadvantage that the electronic terminal cannot properly recognize the information in the QR code.

In order to solve such a problem, various plating and etching methods have been used, but the problem that the electronic terminal cannot recognize has not been solved. However, in a recent experiment, when a paint such as a transparent varnish was used to suppress the prevention of diffuse reflection, the occurrence of diffuse reflection in the QR code area was suppressed as shown in Figs. It was confirmed that the recognition rate of the terminal was increased.

Therefore, when the following paint is applied (coated) on a printing plate for anti-counterfeiting using a metal layer on which the QR code is plated and proliferated, the electronic terminal can be recognized.

On the other hand, the coating for preventing diffuse reflection removes residual solvents harmful to the human body and should not harm the human body at all, so during the coating work, polar organic solvents such as toluene are removed to improve the working environment, and excellent wettability and dryness to the cardboard. You must have a composition. In addition, it is to satisfy the following performance required as an overprinting coating composition. First, ① because of good coating workability, there should be no pinhole, brushing, catering, misting thread, etc., and there should be little increase in viscosity during coating. ② Good drying and no blocking. And ③ As the material (paper) and adhesion are good, there should be no scratches, cracks, or falling off during the process. ④ Do not smear or discolor the ink, or create a flaw, separation, or emboss. To satisfy the above physical properties, water-dispersible copolymer polyester having excellent film-forming ability is used, and an acrylic copolymer and a styrene copolymer in the form of an emulsion are added thereto to provide excellent coatability and adhesion to the paper as the substrate, and also wear resistance. , By developing a composition excellent in surface gloss, heat resistance, durability, weather resistance, etc., the present invention was completed.

Accordingly, the present invention comprises the steps of preparing a transparent film on which micro-patterns are developed; Applying a photoresist to the surface of the micro-polished stainless steel plate and drying to form a photosensitive coating layer; A step in which the transparent film on which the micro-pattern is developed is in close contact with the photosensitive coating layer, exposed to ultraviolet light, and cured; Removing the transparent film on which the micro-pattern is developed, and removing portions of the photosensitive coating layer other than the portion exposed to the ultraviolet rays and cured in a negative form; Forming a convex primary plating growth metal layer between portions exposed to the ultraviolet light and cured; Forming a chromate layer for releasing treatment on the surface of the first plating growth metal layer; And forming a second plating growth metal layer on the first plating growth metal layer on which the chromate layer is formed so that a convex portion is formed on the exposed and cured portion of the ultraviolet ray. Among the methods of manufacturing a printing plate for anti-counterfeiting using a metal layer,
