The anti-counterfeiting of seals should be considered from two aspects: one is the forgeability of seals; The second is the distinguishability of seal. Laser technology and computer technology are at the forefront of scientific and technological development. Inspired by Laser Phototypesetting, laser engraved seals are soon introduced into the field of seal manufacturing and anti-counterfeiting.
Laser engraving machine has successfully replaced the traditional seal engraving method, which has attracted the attention and support of relevant departments and experts. In view of the advantages of monochromaticity, high brightness and good directivity, the laser is used as an invisible "knife" to act on the material, melting and vaporizing the material, forming various desired patterns and characters.
The principle of laser engraving is that the laser beam is transmitted and focused on the surface of the material through the optical mechanism, and the laser beam with high energy density acts on the material to rapidly vaporize and form pits. CO2 laser is suitable for engraving non-metallic materials such as rubber and plastic, ox horn, plexiglass, jade, ink storage pad, bamboo and wood. The depth and accuracy are extremely high. The engraved seals fully meet the industry standards.
How does the laser engraving machine prevent forgery? First, the process is non forgeable and difficult to imitate by hand; Second, it is easy to embody many anti-counterfeiting marks in computer typesetting through laser engraving; Third, it is easy to compare and identify with the sample chapters in the archives through computer image recognition; Fourth, the laser engraving machine can be networked with the national public security system for filing, and beware of forgery.
China is a big country of seals, and the application of high technology in the seal industry should be vigorously strengthened in seal anti-counterfeiting. Seal anti-counterfeiting is a complex system engineering. Chuangxuan laser equipment Co., Ltd. sincerely hopes to contribute to the progress of seal anti-counterfeiting technology and the prosperity of seal industry in China.
