Traceability method of printing ink based on block chain and 5g communication

Abstract

The invention discloses a printing ink traceability method based on block chain and 5G communication, including: a data processing unit, an icon processing unit and an ink printing unit. The identification function and traceability function, and the icon with anti-counterfeiting function, are then printed on the product at one time, which greatly simplifies the process and improves efficiency; at the same time, by combining the two-dimensional code icon with the anti-counterfeiting mark, the corresponding The product code and the corresponding time stamp are saved to the blockchain, so that not only the QR code icon with the anti-counterfeiting mark has the traceability function, but also the blockchain has the traceability function, and the double traceability function guarantees the absolute reliability of the traceability; and, The combination of the anti-tampering function of the blockchain and the anti-counterfeiting function of the anti-counterfeiting mark makes the product have double anti-counterfeiting functions, so that the anti-counterfeiting effect of the product is better; finally, the communication delay through the 5G network is low and the response speed is fast.

Description

technical field [0001] The present invention relates to the field of ink printing, in particular to a printing ink traceability method based on blockchain and 5G communication. Background technique [0002] At present, with the development of the Internet of Things, the application of two-dimensional codes has also been greatly developed, that is, the input of two-dimensional codes on items, such as two-dimensional codes printed on products, and consumers can identify products by scanning the codes . [0003] Compared with 1D code, 2D code is a more advanced barcode format. One-dimensional codes generally can only express information in the horizontal or vertical direction, while two-dimensional codes can store information in both horizontal and vertical directions. Moreover, one-dimensional codes can only be composed of numbers and letters, while two-dimensional codes can store information such as Chinese characters, numbers and pictures, so the application fields of two-...

Problems solved by technology

However, some products not only need the identification function and traceability function of the QR code, but also need the anti-counterfeiting function. The traditional method is to print the QR code on one position of the product and print the anti-counterfeiting mark on another position of the product, so that not only The process is complex and inefficient

[0004] At the same time, because the QR code printed with ink on the product sometimes cannot be printed completely, which will lead to the phenomenon that the QR code on the product cannot be recognized, the product cannot be identified and traced, and the authenticity of the product cannot be verified. The traditional method is that the inspectors use the naked eye to inspect the QR code of each product, which is not only inefficient, but also easy to make mistakes

[0005] Moreover, when an ink printer that prints a two-dimensional code is actually used, if the parameters such as the atmospheric pressure and air specific humidity of the environment where the ink printer is located change greatly, and the operating parameters and ink density of the ink printer do not make adaptive adjustments, the printing The printed two-dimensional code icon is prone to ink shedding, which reduces the pass rate of two-dimensional code icon printing and affects production efficiency
