What anti-counterfeiting technology can be applied to color thermal label paper?

On the color thermal label paper, a variety of anti-counterfeiting technologies can be applied to improve the anti-counterfeiting performance and security of the product. Here are some of the main anti-counterfeiting technologies and their applications:

First, thermal color-changing anti-counterfeiting technology

Technical principle: The use of heat-sensitive materials that change color when heated or cooled. This change can be reversible (i.e., color also returns after the temperature returns) or irreversible.

Application effect: Through the thermal printing technology, the anti-counterfeiting logo with unique pattern, color and texture can be immediately printed on the color thermal label paper. These signs can contain complex miniaturized text, dynamic light, 3D optical effects, etc., to increase the difficulty of counterfeiting.

Second, photochromic anti-counterfeiting technology

Technical principle: The use of light-sensitive materials, when exposed to ultraviolet light or other specific wavelengths of light changes color.

Application effect: By coating light sensitive ink or paint on the label, the color change effect can be achieved under specific lighting conditions, thus verifying the authenticity of the product.

Third, chemical reaction color-changing anti-counterfeiting technology

Technical principle: The label is coated with ink or paint containing a specific chemical composition, and when the label changes with external conditions (such as temperature, humidity, etc.), chemical reactions are triggered to achieve the discoloration effect.

Application effect: This technology can achieve a variety of complex color-changing effects, and because of the unique chemical reaction, it is difficult to be copied.

Fourth, water-sensitive color-changing anti-counterfeiting technology

Technical principle: The label material is sensitive to water, and the color changes when the label is in contact with water.

Application effect: Through soaking, spraying and other ways to achieve the discoloration effect, this technology is often used in the need of waterproof or moisture-proof products.

Fifth, magnetic anti-counterfeiting technology

Technical principle: The paper substrate is coated with magnetic magnetic powder, or the magnetic powder is added to the pulp in a special way when the paper is manufactured to make the paper magnetic.

Application effect: Through the magnetic detection equipment can identify the magnetic anti-counterfeiting label, so as to verify the authenticity of the product.

Sixth, fluorescent anti-counterfeiting technology

Technical principle: Using a special fluorescent ink combined with label printing, the fluorescent effect can be seen under ultraviolet irradiation.

Application effect: This technology is often used to make invisible anti-counterfeiting signs, and anti-counterfeiting information can be seen only under certain conditions, increasing the difficulty of counterfeiting.

Seventh, two-dimensional code and bar code anti-counterfeiting technology

Technical principle: The combination of two-dimensional code or bar code and anti-counterfeiting technology, each product is given a unique anti-counterfeiting code, and recorded and verified through the database.

Application effect: Consumers can scan the QR code or bar code to inquire the authenticity of the product information, to achieve one-to-one anti-counterfeiting traceability.

Eighth, multi-layer anti-counterfeiting technology

Technical principle: The combination of a variety of anti-counterfeiting technologies, such as heat-sensitive discoloration, fluorescence anti-counterfeiting, two-dimensional code anti-counterfeiting and other technologies superimposed together.

Application effect: By building multi-level anti-counterfeiting protection, the anti-counterfeiting performance and security of the product can be greatly improved.

These anti-counterfeiting technologies can be selected and combined according to the characteristics of the product and market demand to achieve the best anti-counterfeiting effect. At the same time, with the continuous development of science and technology, new anti-counterfeiting technologies are also emerging, providing more possibilities for the anti-counterfeiting application of color thermal label paper.
