Point code technology based composite layer product structure

Abstract

The invention relates to a point code technology based composite layer product structure which comprises a presswork body, a multimedia printing area and a point code label, wherein the multimedia printing area is printed on the presswork body; and the point code label is covered and printed on the multimedia printing area. According to the point code technology based composite layer product structure, an existing print appearance is not affected, point codes are unnecessary to occupy a particular block, can be overlapped on the pattern surface, and cannot be copied by a common optical method, and even electronic color scanning technology cannot effectively restore the correct encoding information. According to printing by a specific method, hardware can only identify the matching effective point code layer information, so that complexity and security of encoding are improved, and real point code information can be effectively protected. Non-replicability of point code technology can guarantee the security of product marking of point code and existing products. Therefore, the confusion of products is effectively avoided, quality of accountability is effectively distinguished, and the marking has traceability.

Description

technical field [0001] The invention relates to a dot code printing technology, in particular to a multi-dot code superposition technology. Background technique [0002] At present, the mainstream coding methods on the market are bar codes and Q-R codes. Only one layer of codes can be printed on the surface of the printed matter, and the codes printed in layers cannot be correctly identified, let alone prevent the codes from being copied. [0003] Chinese patent (application number) 99200458.6 applies for an anti-counterfeiting label, which hides a randomly generated anti-counterfeiting code, which is archived in the database and provides inquiry services for consumers through inquiry telephones. It should be said that this digitally coded anti-counterfeiting mark has made substantial progress compared with anti-counterfeiting methods such as laser labels and watermarks, and the query method is also very simple and fast. However, there is the phenomenon of recycling old co...

Problems solved by technology

[0006] The current product identification content on the market cannot effectively prevent product confusion, the identification content cannot effectively distinguish quality responsibility, the identification does not have reliable product traceability, and the product identification is easy to be forged by optical means, which is not safe.
