Technical Field

The invention relates to a method for improving the code scanning recognition rate of a product identification code, in particular to a method for improving the code scanning recognition rate of a starlight film product identification code.

Background

The starlight film is a new product of packaging materials, also known as a starry sky dull polish membrane, starry sky flashing membrane etc., is the light film that light film manufacturers made the processing of secondary technology on ordinary light film surface, and its processing mode generally is for utilizing the dull polish technology to form the granule that can realize the diffuse reflection effect on light film surface, can improve the visual effect after the tectorial membrane like this, sees the sensation that all there is golden light flashing at any angle. The star light film is directly coated outside the product, secondary process synergistic treatment (embossing, silk printing, transferring and the like) is not needed to be carried out on the surface of the film after the common light film is coated, the cost is not needed to be improved due to the improvement of the packaging texture, and the waste of social resources is reduced. Therefore, the starlight film is commonly used for cosmetic packages, electronic product packages, wine packages and the like in recent years, and the surface texture of the gift box is enhanced.

However, the product identification code is arranged on the outer package of the product, such as a bar code (e.g., EAN13 code, which is a bar code protocol and standard of a general terminal product and is mainly applied to supermarkets and other retail industries), a two-dimensional code, etc., the product identification code needs to be scanned and identified by a code scanner in each link of production, transportation, sale, etc., the code scanning identification code needs to utilize light reflection of the product identification code, after the product is coated with a starlight film, due to the influence of diffuse reflection of particles on the starlight film, the identification accuracy of the product identification code by the code scanner is greatly reduced, not only the effective monitoring of the product circulation link is influenced, but also the detection standard of the identification code cannot be reached, and if the product is used in a product with high quality requirement, brand influence and huge economic loss are more likely to be caused.

At present, no solution for influencing the code scanning recognition rate of the product identification code aiming at the starlight film exists.
