Variable data printing and protection and failure recognition method based on traditional printing form

Abstract

The invention discloses a variable data printing and protection and failure recognition method based on a traditional printing form. The variable data graph randomly generated by a computer is adopted. The data printing technology is combined with traditional offset printing. Meanwhile, the variable data graph is locally coated and shielded by adopting an anti-detection and scrubbing-resistant material, so that variable data information is prevented from being leaked. After a data terminal user is clarified, destructive removal is carried out on the coating by the terminal user, and then datareading is carried out by utilizing a scanning technology. The data can realize multiple functions of book traceability retrieval, image information transmission, network link entry and the like. Andmeanwhile, server background software is used for identifying and locking the ip address of the used equipment, so that leakage of linked database data files is prevented.

Description

technical field [0001] The invention belongs to a method for using a two-dimensional code, in particular to a variable data printing and protection and failure identification method based on a traditional printing form. Background technique [0002] If traditional book publishing needs audio and video as content extensions, such as educational books, it will often be accompanied by a CD. However, the use of optical discs is cumbersome and requires specific equipment to play, and the process is cumbersome. Nowadays, many computers, especially notebooks, no longer have built-in optical drives, and using external devices will increase the cost of playback for users; at the same time, because storage media such as optical discs are not interactive, the content cannot be changed once it is released. With the rapid update of information, the efficiency of content dissemination and update is greatly reduced. Therefore, the advantages of QR codes are reflected. For example, it can...

Problems solved by technology

For example, it can be viewed by scanning the code, and the user’s playback cost is low; placing QR code tutorials next to the knowledge points is more relevant and easier for readers to understand; however, most books are printed by traditional printing methods, so books The QR codes on the website are all marked with the same QR code in the whole batch. Counterfeiters will scan the QR code of the original book and copy it on the pirated book, so as to counterfeit the original book and cause direct losses to the publishing unit.
