With the continuous advancement of science and technology, anti-counterfeiting technology is also improving day by day to protect the rights and interests of consumers and enterprises. Among the many anti-counterfeiting technologies, laser anti-counterfeiting labels have been widely used due to their unique optical effects and high anti-counterfeiting performance. So, what is the product principle of laser anti-counterfeiting labels?

The production of laser anti-counterfeiting labels mainly relies on laser imaging technology and optical interference principle. First, it creates a surface with a specific pattern and uniform gloss on the surface of the label through subtle structural changes produced by the refraction of a high-energy laser beam or laser beam refraction. This glossy surface looks like a glossy metallic film coated with a unique optical effect.
During the manufacturing process, laser security labels go through three main steps: pre-treatment, laser imaging, and glossy surface formation.
In the pre-processing stage, a laser pattern is created by laser engraving on the basis of the printed pattern. This pattern can be made on metal foil, film, or label stock materials.
In the laser imaging phase, the action of the laser beam and the reflected light creates specific reflections and scattering effects in the imaging area. In this process, the laser beam creates a series of tiny holes or steps on the surface of the label.
Finally, a uniform glossy surface is formed, which gives the label a metallic look, adding to its anti-counterfeiting properties.
The anti-counterfeiting performance of laser anti-counterfeiting labels mainly depends on the interference, diffraction, diffraction and reflection of physical effects and light. These phenomena affect the propagation, refraction and reflection of light waves, making the optical patterns and patterns of the logo have very high anti-counterfeiting performance. Due to the complex manufacturing process of laser anti-counterfeiting labels, and the optical pattern of each label is unique, this kind of label has the characteristics of extremely high anti-counterfeiting and difficult to imitate.
In addition, laser anti-counterfeiting labels also have the advantages of easy identification, beautiful appearance, environmental protection and durability. Consumers can easily distinguish the authenticity of a product simply by looking at the gloss and pattern of the label. At the same time, laser anti-counterfeiting labels have a long service life, are not easy to wear, and can maintain good anti-counterfeiting effects in various environments.
In conclusion, laser security labels utilize laser imaging technology and the principle of optical interference to achieve a high degree of security by creating a surface with a specific pattern and uniform gloss. This anti-counterfeiting technology not only improves the safety of the product, but also protects the rights and interests of consumers and businesses. With the continuous development of science and technology, laser anti-counterfeiting labels will play a greater role in the field of anti-counterfeiting, bringing more convenience and safety to our lives.
