Description
Technical Field
The invention relates to the technical field of coating, in particular to a code making method for improving the recognition rate of a fluorescent two-dimensional code.
Background
With the popularization of smart phones in daily life, two-dimensional codes are increasingly applied in daily life, and product anti-counterfeiting and information tracing are included. The two-dimensional code for the application is generally common to the surface of a packing material of a product, but not the surface of the product. Most of the common two-dimensional codes printed on the surfaces of products can affect the appearance aesthetic feeling of the products.
The two-dimensional code drawn by the ultraviolet fluorescent ink can not only increase the concealment performance of the anti-counterfeiting function, but also does not affect the appearance effect. Some patents on fluorescent two-dimensional codes have emerged in recent years. For example, patent application No. 202010156823.9 entitled "fluorescent two-dimensional code stamping foil and preparation method and application thereof" provides a method for printing fluorescent two-dimensional codes by stamping. In addition, patent application No. 201910643700.5 discloses a method for preparing a multiple anti-counterfeiting fluorescent two-dimensional code device, which describes a method for drawing a multi-layer fluorescent two-dimensional code in a hollow manner. Although both methods have feasibility, the technical scheme shows that the two methods have complex processes for producing the fluorescent two-dimensional code and are limited in applicable scenes.
At present, a simpler fluorescent two-dimensional code manufacturing process is already available on the market. The readable fluorescent two-dimensional code can be manufactured by using a continuous ink-jet technology and quick-drying ultraviolet fluorescent ink. Advantages of the continuous inkjet technique: (1) the type of the two-dimensional code, such as Quick Response two-dimensional code and Data Matrix two-dimensional code, can be freely changed according to the setting of the program; (2) the requirement on the flatness of the code carrier is low, and the code carrier can be used for the surface of a product with more complex modeling and can not be limited to a packing material; (3) the code making speed is fast, the process is simple and the cost is low. However, its drawbacks are also very significant: (1) the code-spraying method of '1 to 1' is used, that is, 1 ink dot corresponds to 1 basic dot of the two-dimensional code, as shown in fig. 1. The prepared fluorescent two-dimensional code has poor quality, so that the reading effect is unstable; (2) the prepared fluorescent two-dimensional code is exposed to air, so that the service life of the fluorescent two-dimensional code is short.
