[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] In one embodiment, such as Figure 1 As shown, a graded traceability carton face sheet 100 is provided. The graded traceability carton face sheet 100 includes: a substrate pattern layer 110, a visible code non-contact printing layer 120, and a hidden code non-contact printing layer 130. The visible code non-contact printing layer 120 is printed with a first micro dot code 121 and a QR code 122; the hidden code non-contact printing layer 130 is printed with a second micro dot code 131; and the substrate pattern layer 110 is printed with a legal text area 123.

[0038] In implementation, the substrate pattern layer 110 is a major part of the graded traceability carton face paper 100. It typically uses high-quality paper materials, such as white cardboard, grey-backed white cardboard, or kraft paper. These materials have good printability and physical strength, meeting packaging requirements. The substrate pattern layer 110 has a reserved area 123 for legally required text, such as product name, production date, and expiration date. This legally required text is an important indicator of product compliance, ensuring that the product meets the requirements of relevant laws and regulations. The substrate pattern layer 110 can also be printed with brand logos and product graphics. If legally required text is pre-printed in the substrate pattern layer 110, it is printed within the legally required text area 123. The brand logo can be the brand's logo, used to enhance brand recognition. In addition to legally required text and brand logos, the substrate pattern layer 110 can also print product names, product images, instructions for use, and other information. This graphic information helps consumers better understand the product, improving its usability and recognizability.

[0039] The contactless printing layer 120 is an important component of the carton's surface paper, providing product traceability. This layer primarily prints traceability codes, a coding system used to track and record the entire process of a product from production to consumption, linking it to key data such as production information, batch number, and expiration date. Through traceability codes, businesses can achieve full-process monitoring of their products, ensuring product quality and safety, improving supply chain transparency, and providing consumers with detailed product information, enhancing trust and satisfaction.

[0040] The contactless printing layer 130 refers to the printing of an imperceptible code in a specific area of ​​the cardboard box liner. The second micro-dot code 131 printed on the contactless printing layer 130 typically requires specialized scanning equipment or a light source to read. The main purpose of the contactless printing layer 130 is to provide enhanced security and anti-counterfeiting features. The code printed on the contactless printing layer 130 is generally difficult to identify with the naked eye and requires special equipment to read. This concealment increases the security of the second micro-dot code 131, preventing counterfeiting or tampering.

[0041] In this embodiment, the traceability code includes a first micro-dot code 121 and a QR code 122. The first micro-dot code 121 employs a micro-dot code encoding structure. Micro-dot codes are high-density codes, typically composed of tiny dot arrays, making them difficult to identify directly with the naked eye. They are used for quality control and traceability during product manufacturing. Unlike traditional QR codes, the micro-dot code encoding structure allows for the storage of a large amount of information in a very small space and offers higher security and is difficult to copy. Each micro-dot is part of the information and can be quickly and accurately decoded using a dedicated reading device or smartphone application. The QR code 122 is a widely used encoding format that can store a large amount of information. Consumers can scan the QR code using smartphones or other devices to obtain detailed product information, such as production batch, logistics information, and quality inspection reports. This helps consumers understand the authenticity and compliance of the product.

[0042] The aforementioned graded traceability cardboard box liner and graded traceability cardboard box liner coding system include: the graded traceability cardboard box liner comprises a substrate pattern layer and a non-contact printing layer for clear coding, wherein: the non-contact printing layer for clear coding is printed with a first micro-dot code and a QR code; the substrate pattern layer is printed with legally mandated text areas. Using this method, by combining the micro-dot code and the QR code for coding, it is possible to use the QR code to complete the association between different packaging groups, and the QR code to ensure the readability of the micro-dot code. Furthermore, the technical characteristics of the micro-dot code allow it to be printed on the legally mandated text areas on the cardboard box liner, improving the tamper-proof nature of the traceability code and thus enhancing the product traceability effectiveness of the graded traceability cardboard box liner.

[0043] In one embodiment, such as Figure 1 As shown, the graded traceability cardboard box liner 100 also includes:

[0044] The second micro dot code 131 is printed with K100 black ink or invisible ink.

[0045] In this embodiment, the second micro-dot code 131 is the main printed content of the non-contact printing layer 130 of the cryptographic code. Printed with K100 black ink or invisible ink, the second micro-dot code 131 possesses high concealment and security, primarily used for deep anti-counterfeiting and traceability of products. K100 black ink is a high-contrast black ink that can form clear black dots on paper and has good adhesion and durability, maintaining the integrity of the code even when scratched or rubbed on the paper surface. The second micro-dot code 131 printed with K100 black ink has high visibility but is not easily detected under ordinary light. Invisible ink is a special ink that is almost invisible under normal light, only becoming visible under specific light sources (e.g., ultraviolet lamps). The second micro-dot code 131 printed with invisible ink has extremely high concealment, making it difficult to copy or counterfeit. The use of invisible ink further enhances the security and anti-counterfeiting function of the code.

[0046] In one embodiment, the code values ​​of the first micro-dot code 121, the second micro-dot code 131, and the QR code 122 are in the same or corresponding relationship during printing.

[0047] In this embodiment, to ensure the accuracy and integrity of product traceability, the code values ​​of the first micro-dot code 121, the second micro-dot code 131, and the QR code are usually designed with the same or corresponding relationships. The consistency or correspondence of the code values ​​of the first micro-dot code 121, the second micro-dot code 131, and the QR code enables seamless connection of product information in different traceability stages, simplifies the information reading and verification process, and effectively prevents information gaps if any of the first micro-dot code 121, the second micro-dot code 131, or the QR code is damaged.

[0048] When multiple sets of first micro-dot codes 121 and second micro-dot codes 131 are required for the graded traceability carton faceplate 100 on the same page, in the packaging patterns of multiple graded traceability carton faceplates 100 on the same page, the code values ​​of several QR codes and several micro-dot codes in each graded traceability carton faceplate 100 follow the corresponding relationship, and the code values ​​of the first micro-dot codes 121 between graded traceability carton faceplates 100 on different pages remain different.

[0049] In an optional embodiment, consumers can perform anti-counterfeiting verification by scanning the first micro-dot code 121, the second micro-dot code 131, and the QR code 122 to obtain the same or corresponding code value information. That is, if the code value does not match or is missing, it indicates that the product may have been tampered with or counterfeited. Optionally, multiple verifications can be performed by scanning the first micro-dot code 121, the second micro-dot code 131, and the QR code 122 at different stages, which can further improve the security of anti-counterfeiting. For example, after the micro-dot code verification is passed in the production stage, a second verification can be performed at the sales stage using the QR code.

[0050] In one embodiment, such as Figure 2 As shown, the legal text area 123 of the substrate pattern layer 110 is set in a dark background area, and the substrate pattern layer 110 also includes a dark pattern, wherein:

[0051] The second micro-dot code 131 is located in the dark background area or inside the dark pattern of the non-contact printing layer 130 of the cryptographic code.

[0052] In this embodiment, the size and shape of the second micro-dot code are both located in the LOGO or legal text area of ​​the substrate pattern layer. In the non-contact printing layer 120, the second micro-dot code 131 is arranged in the dark background area or inside the dark pattern, and is closely combined with the LOGO or legal text area 123 of the substrate pattern layer 110. Through the high contrast characteristics of the dark background, the second micro-dot code 131 is more visually concealed, so that it is not directly exposed, but the scanning device can read it quickly and accurately.

[0053] In one embodiment, the legal text area 123 in the dark background area also includes legal text, which is light-colored and has a height greater than or equal to 3mm.

[0054] In this embodiment, by setting the legal text to a light color and having a character height greater than or equal to 3mm, interference from the K-plate halftone dots on the recognition of the second micro-dot code 131 is avoided, thus ensuring the recognition rate.

[0055] In one embodiment, such as Figure 2 As shown, the legal text area 123 of the substrate pattern layer 110 is a light background color area, which includes a reserved blank area, wherein:

[0056] The first micro-dot code 121 in the clear code non-contact layer is aligned and printed with the light background color area in the substrate pattern layer 110.

[0057] The QR code 122 in the non-contact layer is aligned with the reserved blank area in the substrate pattern layer 110 and printed.

[0058] In this embodiment, by aligning and printing the first micro dot code 121 with the light background color area in the substrate pattern layer 110, the first micro dot code 121 is embedded in the legal text area 123 such as the factory name and address, and ingredient list on the outer surface of the graded traceability carton. Since the first micro dot code 121 is formed by micro-pitch coding to form micron-level code dots, the first micro dot code 121 will not affect text recognition.

[0059] The legal text area is typically located on the substrate pattern layer 110 of the cardboard box liner. This area uses high-quality printing materials and design, possessing good physical strength and abrasion resistance. The substrate pattern layer 110 of the cardboard box liner usually uses durable paper materials (such as whiteboard paper, grey-backed white cardboard, or kraft paper). This material undergoes special treatment during printing and processing to resist certain physical damage and friction. Simultaneously, the legal text area includes key information such as the product name, production date, and expiration date, serving as an important indicator of product compliance. According to relevant laws and regulations, the legal text within the legal text area 123 must be clearly and completely displayed on the product packaging. Therefore, when designing and producing cardboard boxes, companies need to strictly comply with legal and regulatory requirements to ensure the integrity of the legal text area. This requirement guarantees that the legal text area 123 will not be easily damaged from the outset. Therefore, printing the first micro-dot within the legal text area 123 allows for the identification of the first micro-dot code 121 within the legal text area 123 even if the QR code 122 and serial number are damaged, via tools such as mobile phones, thereby enabling the retrieval of product flow information. By using the non-contact printing layer 120 to spray the sparse dot matrix code of the first micro dot code 121 onto the image or legal text area 123, the visual communication of the pattern brand marketing of the graded traceability carton face paper is achieved without affecting the graded traceability carton face paper. At the same time, it provides consumers with a way to check for counterfeit products, thereby improving the product traceability effectiveness of the graded traceability carton face paper.

[0060] In one embodiment, if the legal text area 123 contains legal text, the first micro-dot code 121 is a code with arbitrary spacing printed with invisible ink or a micro-dot code with a ratio greater than 4 printed with black ink.

[0061] In one embodiment, the first micro dot code 121 is printed with K100 black ink.

[0062] Based on the same inventive concept, this utility model embodiment also provides a graded traceability carton face paper inkjet coding system. The solution provided by this graded traceability carton face paper inkjet coding system is similar to the solution described in the above method. Therefore, the specific limitations of one or more graded traceability carton face paper inkjet coding system embodiments provided below can be found in the above-described limitations on graded traceability carton face paper, and will not be repeated here.

[0063] In one embodiment, a graded traceability carton face paper inkjet printing system is provided, the system comprising an inkjet printer and carton face paper to be inkjet printed, wherein:

[0064] The cardboard face paper to be inkjet printed includes a substrate pattern layer and a non-contact printing layer for clear codes.

[0065] The inkjet printing equipment is used to print the first micro-dot code and QR code on the surface of the carton to be printed.

[0066] In one embodiment, the inkjet printer uses high-precision printing technology to ensure the accuracy and clarity of the first micro-dot code and QR code. The inkjet printer uses advanced printing technology to achieve high-precision printing of micro-dot codes and QR codes. The small size and high-density printing of micro-dot codes enable them to provide effective traceability information without affecting visual aesthetics.

[0067] The inkjet printing equipment employs non-contact printing technology, eliminating the need for direct contact with the cardboard box linerboard and minimizing damage to the paper surface. This printing method improves efficiency and accuracy while protecting the integrity of the substrate pattern layer. Optionally, the equipment features rapid printing capabilities, enabling the printing of large quantities of cardboard box liners in a short time, making it suitable for large-scale production scenarios and meeting the demands of rapid production and traceability. Furthermore, the equipment integrates multiple functions, supporting various encoding formats such as micro-dot codes, QR codes, or barcodes. This multi-functional integration enhances the equipment's application flexibility, meeting the traceability and anti-counterfeiting requirements of different products.

[0068] In one embodiment, the system further includes a coding control device electrically connected to the coding device.

[0069] In this embodiment of the invention, the electrical connection between the inkjet control device and the inkjet printing device can be divided into two parts: wired connection and network connection. Wired connection is the most common connection method between the inkjet control device and the inkjet printing device, typically using standard communication interfaces and cables, such as USB (Universal Serial Bus) connection or serial port connection. The inkjet control device and the inkjet printing device can also be connected via a network, which can be a wireless network. The inkjet printing device can connect to the inkjet control device via a wireless network (Wi-Fi), providing a more flexible deployment method.

[0070] The inkjet printing control device is used to generate the code value of the first micro dot code, the code value of the first micro dot code and the code value of the QR code or their association relationship. The code value of the first micro dot code and the code value of the first micro dot code and their association relationship with the QR code can be sent to the inkjet printing system through offline data packets or online push cache.

[0071] In one specific embodiment, the inkjet printing control device generates the code value of a first micro-dot code according to preset rules and establishes an association between the code value of the first micro-dot code and the code value of the QR code. Depending on the actual working environment, the inkjet printing control device transmits the generated code value of the first micro-dot code and the association to the inkjet printing device via offline data packets or online push cache. After receiving the code value and association, the inkjet printing device performs a high-precision printing operation, accurately printing the first micro-dot code and the QR code onto the non-contact printing layer of the carton's face paper. After printing is completed, an additional quality inspection system checks the printing effect to ensure the integrity and accuracy of the micro-dot code and the QR code.
