Description

Technical Field

[0001] The invention relates to the field of anti-counterfeiting hangtags and technologies, and in particular to a hangtag with an anti-counterfeiting color two-dimensional code and a method for printing the color two-dimensional code. Background Art

[0002] The main functions of hangtags include brand promotion, product description, anti-counterfeiting protection and price identification. By scanning the QR code on the hangtag, you can know the authenticity of the product, as well as the detailed information and instructions of the product. QR code has become a very popular information transmission and anti-counterfeiting authentication tool. However, with the continuous advancement of technology, traditional one-dimensional codes can no longer meet people's growing demand for information security, so the clarity and stability of QR codes are very important. How to achieve this is a technical problem that many companies should solve;

[0003] In view of the above technical problems, a method for printing a two-dimensional code is disclosed in the announcement number CN110682706A, which sprays white epoxy primer on the product and then prints the two-dimensional code on the white epoxy primer by laser. In this way, the two-dimensional code is not directly printed on the product, which is easy to be damaged by paper, so that the two-dimensional code is more solid. The color of the two-dimensional code is black and the background is white, and the contrast is clearer.

[0004] The above patent also has the following shortcomings: compared with the traditional black and white QR code, it has poor anti-counterfeiting properties and poor aesthetics, resulting in poor anti-counterfeiting and authenticity identification capabilities. It also has poor error correction capabilities and poor recognition performance, which is not suitable for use in various places. Summary of the invention

[0005] The purpose of the present invention is to provide a tag with an anti-counterfeiting color QR code and a method for printing a color QR code, which has the advantage of good anti-counterfeiting effect, adopts a triple anti-counterfeiting method to improve the anti-counterfeiting property, and can also improve the performance of authenticity identification, thereby improving the workability, and at the same time can also improve the recognition performance and can be applicable to different places, so as to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a hangtag with an anti-counterfeiting color QR code, comprising an anti-counterfeiting hangtag:

[0007] A color anti-counterfeiting QR code is printed on the surface of the anti-counterfeiting tag.

[0008] A method for printing a color anti-counterfeiting two-dimensional code, applied to the anti-counterfeiting tag according to claim 1, comprising the following steps:

[0009] Step 1: Primer printing: spray the pre-prepared epoxy primer on the surface of the tag through a UV machine. After the epoxy primer solidifies, print it with the ink of the required color.

[0010] Step 2: ink preparation: prepare black ink, green ink, blue ink and red ink in advance and add them into the corresponding storage boxes in the UV machine for use and mixing;

[0011] Step 3: Color mixing: the UV machine extracts inks of different colors into corresponding mixing barrels for color adjustment, and mixes them in a mixed manner;

[0012] Step 4: Color QR code generation: first draw a color QR code graphic, which contains a serial anti-counterfeiting number, and then import it into the database. Connect the color QR code graphic in the database to the UV machine, and use the UV machine to print the color QR code on the surface of the tag printed with white epoxy primer and then cure it.

[0013] Exemplarily, in the primer printing, the primer and the ink are cured by top and bottom dual curing;

[0014] The curing method includes ultraviolet irradiation and curing by a heating wire group with a thyristor temperature controller;

[0015] The ultraviolet irradiation solidifies the primer and the color two-dimensional code formed by the printed color ink from top to bottom;

[0016] The heating wire group with the thyristor temperature controller generates temperature from inside the UV machine to cure the hang tag from bottom to top.

[0017] Exemplarily, in the color mixing, a micro ink extraction pump is used to extract the required colors into several mixing barrels for ink mixing and mixing;

[0018] The color mixing is performed based on two, three, four or other colors of ink;

[0019] The mixing barrel adopts a micro motor to drive the mixing stirring rod to fully mix the ink in the mixing barrel.

[0020] Exemplarily, the generation of the color QR code includes: a version information area, a format area, a data and fault-tolerant key area, a data requirement module area, a positioning area, a correction area and a timing area.

[0021] Exemplarily, in the generation of the color QR code, color ink is printed and data is input in the version information area, format area, data and fault-tolerant key area, data requirement module area, positioning area, correction area and timing area respectively, and the data forms a data code;

[0022] Data encoding contains all the information of the input string and selects random numbers to add to it.

[0023] Exemplarily, the version information area is formed by permutations and combinations of colored rectangles, different permutations and combinations form different versions, and different versions carry different amounts of information;

[0024] It is formed in the form of binary data to store data, including numbers, characters, and Chinese characters. It is also fault-tolerant and can be read normally even if part of it is damaged.

[0025] In the format area, based on the binary algorithm, a combination is made according to a specific coding rule to form a binary sequence, which is encoded in a single digit and a single letter manner, or encoded in a single digit and a single letter manner, etc.

[0026] Exemplarily, the data and fault-tolerant key area includes:

[0027] In the data area, information is represented by a combination of colored blocks based on a binary algorithm. Color patterns are combined according to specific coding rules to form a binary sequence that stores various types of data, including numbers, letters, special characters, Chinese character codes, etc. The detailed data content depends on the coding standard and coding content adopted by the QR code.

[0028] The secret key area allows the information on the barcode to be correctly restored even if the QR code is not fully recognized or the barcode is damaged. By adding additional data encoding to the QR code, the encoding is used to detect and repair errors that may occur during the transmission process during decoding, ensuring the integrity and accuracy of the data.

[0029] Exemplarily, in the data requirement module area, based on a binary algorithm, the recognition device captures an image and analyzes the color contrast therein to parse out the binary code sequence in the QR code, and then uses a corresponding decoding algorithm to convert the binary data into readable characters, including numbers, letters, special characters, Chinese character codes, etc.;

[0030] In the positioning area, the corresponding positioning symbols are printed at the three corners of the QR code to form the positioning area. The positioning area can be quickly identified when using an identification device. The three-point positioning method can determine the position and angle of the QR code, and the information in the QR code can be decoded from different directions and angles.

[0031] Exemplarily, in the correction area, a correction line is formed by one or more groups of adjacent continuous deep and shallow modules of different single module widths and lengths, and auxiliary correction patterns arranged on the four sides of the code image;

[0032] The timing area, formed by alternating colored squares running horizontally and vertically between three viewfinder patterns, enables identification of data cells in the QR code, including when damaged or distorted.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention achieves the advantages of anti-counterfeiting performance, query convenience, aesthetics, information storage capacity and scope of application by changing the printing method and ink setting. The formed color two-dimensional code not only has digital information anti-counterfeiting, but also incorporates color information and material characteristic information to form a triple anti-counterfeiting mechanism, which makes it difficult for counterfeiters to copy its complex color changes and characteristics, thereby improving the authenticity identification ability of the product.

[0035] Other features and advantages of the present invention will be described in the following description, and partly become obvious from the description, or be understood by implementing the present invention.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention provides a hangtag with an anti-counterfeiting color two-dimensional code, including an anti-counterfeiting hangtag:

[0039] A color anti-counterfeiting QR code is printed on the surface of the anti-counterfeiting tag.

[0040] A method for printing a color anti-counterfeiting two-dimensional code, applied to the anti-counterfeiting tag according to claim 1, comprising the following steps:

[0041] Step 1: Primer printing: spray the pre-prepared epoxy primer on the surface of the tag through a UV machine. After the epoxy primer solidifies, print it with the ink of the required color.

[0042] Step 2: ink preparation: prepare black ink, green ink, blue ink and red ink in advance and add them into the corresponding storage boxes in the UV machine for use and mixing;

[0043] Step 3: Color mixing: the UV machine extracts inks of different colors into corresponding mixing barrels for color adjustment, and mixes them in a mixed manner;

[0044] Step 4: Color QR code generation: first draw a color QR code graphic, which contains a serial anti-counterfeiting number, and then import it into the database. Connect the color QR code graphic in the database to the UV machine, and use the UV machine to print the color QR code on the surface of the tag printed with white epoxy primer and then cure it.

[0045] Prepare the ink required for the background color in advance, such as the black, green, blue and red inks mentioned above. If needed, you can add other color inks, such as yellow, purple and silver, and then add them to the UV machine. When you need to print a color QR code, import the color QR code into the database according to the system programming. At this time, the UV machine will extract the required color ink from the color QR code, and extract the inks of different required colors into different mixing containers for mixing. When the required color ink is extracted, it is printed on the surface of the tag after spraying the primer.

[0046] Preferably, in primer printing, the primer and ink are cured by top and bottom dual curing;

[0047] The curing method includes ultraviolet irradiation and curing by a heating wire group with a thyristor temperature controller;

[0048] The ultraviolet irradiation solidifies the primer and the color two-dimensional code formed by the printed color ink from top to bottom;

[0049] The heating wire group with the thyristor temperature controller generates temperature from inside the UV machine to cure the hang tag from bottom to top.

[0050] The curing method uses ultraviolet irradiation and temperature-controlled heating to achieve double scratching of the tag, which can effectively improve the curing effect and efficiency.

[0051] Among them, in color mixing, a micro ink extraction pump is used to extract the required color into several mixing barrels for ink mixing and mixing;

[0052] The color mixing is performed based on two, three, four or other colors of ink;

[0053] The mixing barrel adopts a micro motor to drive the mixing stirring rod to fully mix the ink in the mixing barrel.

[0054] Inks of corresponding colors are extracted and mixed as needed to form new colors, and then printing is performed. Different colors are printed in different areas to form a full color, thereby improving the recognition of the QR code.

[0055] Furthermore, the generation of the color QR code includes: version information area, format area, data and fault-tolerant key area, data requirement module area, positioning area, correction area and timing area.

[0056] In addition, in the generation of the color QR code, color ink is printed and data is input in the version information area, format area, data and fault-tolerant key area, data requirement module area, positioning area, correction area and timing area respectively, and the data forms a data code;

[0057] Data encoding contains all the information of the input string and selects random numbers to add to it.

[0058] The version information area is formed by the arrangement and combination of colored rectangles. Different arrangements and combinations form different versions, and different versions carry different amounts of information.

[0059] It is formed in the form of binary data to store data, including numbers, characters, and Chinese characters. It is also fault-tolerant and can be read normally even if part of it is damaged.

[0060] In the format area, based on the binary algorithm, a combination is made according to a specific coding rule to form a binary sequence, which is encoded in a single digit and a single letter manner, or encoded in a single digit and a single letter manner, etc.

[0061] Among them, the data and fault-tolerant key areas include:

[0062] In the data area, information is represented by a combination of colored blocks based on a binary algorithm. Color patterns are combined according to specific coding rules to form a binary sequence that stores various types of data, including numbers, letters, special characters, Chinese character codes, etc. The detailed data content depends on the coding standard and coding content adopted by the QR code.

[0063] The secret key area allows the information on the barcode to be correctly restored even if the QR code is not fully recognized or the barcode is damaged. By adding additional data encoding to the QR code, the encoding is used to detect and repair errors that may occur during the transmission process during decoding, ensuring the integrity and accuracy of the data.

[0064] In the data requirement module area, based on the binary algorithm, the recognition device captures the image and analyzes the color contrast therein to parse the binary code sequence in the QR code, and then uses the corresponding decoding algorithm to convert the binary data into readable characters, including numbers, letters, special characters, Chinese character codes, etc.

[0065] In the positioning area, the corresponding positioning symbols are printed at the three corners of the QR code to form the positioning area. The positioning area can be quickly identified when using an identification device. The three-point positioning method can determine the position and angle of the QR code, and the information in the QR code can be decoded from different directions and angles.

[0066] The correction area is composed of a correction line composed of one or several groups of adjacent continuous deep and shallow modules with different single module widths and lengths, and auxiliary correction graphics arranged on the four sides of the code diagram;

[0067] The timing area, formed by alternating colored squares running horizontally and vertically between three viewfinder patterns, enables identification of data cells in the QR code, including when damaged or distorted.

[0068] In summary, the advantages of anti-counterfeiting performance, query convenience, aesthetics, information storage capacity and scope of application are achieved. The formed color QR code not only has digital information anti-counterfeiting, but also integrates color information and material characteristic information to form a triple anti-counterfeiting mechanism, which makes it difficult for counterfeiters to copy its complex color changes and characteristics, improves the authenticity identification ability of the product, and makes the query and identification process simpler and more intuitive. Consumers do not need to enter lengthy anti-counterfeiting codes. They only need to scan the color-changing QR code through mobile devices such as mobile phones, and the system can automatically prompt the product's anti-counterfeiting code and color information. This scan-and-check method greatly improves the user experience and makes anti-counterfeiting queries more convenient. The aesthetics has been significantly improved. The rich color and pattern design makes the QR code itself a visual highlight, forming a better integration with the product packaging, and improving the overall aesthetics of the product. A more efficient encoding method is adopted, which can store more information in a limited space. More product information, promotional content, etc. can be embedded in the QR code to achieve more marketing and interactive functions. It has a wider scope of application and stronger error correction and anti-distortion capabilities. Therefore, it can be used in various environments, whether indoors or outdoors, flat or curved. It can maintain good recognition performance.
