In recent years, due to the proliferation of counterfeit and shoddy goods, the use of anti-counterfeiting technology has become increasingly important in identifying and preventing counterfeit and shoddy goods. Printing anti-counterfeiting marks on their products has become a way for famous brand manufacturers and companies that produce famous and high-quality products to protect themselves. an effective measure. Currently, there are hundreds of products with anti-counterfeiting marks on the Chinese market, such as Xiafei cosmetics, Red Star Erguotou wine, and floppy disks produced by 3M for computers. 1． Reactive SK temperature-controlled anti-counterfeiting mark: As long as the trademark is slightly heated, the anti-counterfeiting color will immediately fade away, showing the production mark of the anti-counterfeiting manufacturer; after cooling down, the anti-counterfeiting color will quickly restore and the anti-counterfeiting mark will be re-covered.
2. Fluorescent anti-counterfeiting marks: When illuminated by a special anti-counterfeiting fluorescent lamp, the marks printed with anti-counterfeiting fluorescent ink will light up and show bright red, orange, yellow-green or green fluorescence. They have high fluorescence intensity and good printing adaptability.
3. Invisible technology anti-counterfeiting mark: Based on the principle of holographic anti-counterfeiting marks, the top surface of the metal bottle cap is used to directly create a concealed true-shape flashing and discolored anti-counterfeiting mark. This kind of mark can reflect a specific pattern or glyph when illuminated by sunlight or a spotlight.
4． Laser holographic anti-counterfeiting marks: Based on the principle of laser interference, patterns or characters are photographed from different levels and angles, and then superimposed to produce different color effects. This kind of anti-counterfeiting mark has high technical content and is difficult to copy, so it should be promoted and promoted.
5. Photosensitive and temperature-sensitive dual anti-counterfeiting mark: a double anti-counterfeiting mark composed of a base layer and a coating layer containing light-sensitive and temperature-sensitive coatings respectively. When the selected photosensitive paint is irradiated by natural light and ultraviolet rays, the color will quickly change from light to dark within 2-6 seconds, and a reversible reaction will occur; when the temperature-sensitive paint is touched with a finger for 5-10 seconds at room temperature, the color will quickly change from dark to light and a reversible reaction will occur. . When using it, consumers only need to gently press the anti-counterfeiting mark on the product with their fingers, and the color will change after 5 seconds. 1． American 3M company reverse anti-counterfeiting label: 3M company’s original products are all equipped with watermark reflective labels. The identification method is: hold the flashlight between your eyes and parallel to your eyes, shine the light source on the label, and follow the light source with your eyes. The label will reflect the shining 3M watermark, which can distinguish authenticity and cannot be forged.
2. The "shape memory" anti-counterfeiting mark on Japan's Mitsubishi Heavy Industries air conditioner: Use a hair dryer (hair dryer) to apply the "Mitsubishi Heavy Industries anti-counterfeiting mark" on the indoor/outdoor unit of the "Mitsubishi Heavy Industries air conditioner" "Blow hot air for 10-15 seconds. After the trademark becomes soft, press it with your fingers to deform it and wait for it to cool and harden. Then blow hot air to the deformed trademark again. "Mitsubishi Heavy Industries Anti-Counterfeiting Trademark" can restore its original appearance. This method of identification, called shape memory function, can be repeated.
In order to gradually standardize anti-counterfeiting technology products, the State Administration of Quality and Technical Supervision issued six national standards for anti-counterfeiting technology products in 1997. As a mandatory national standard, the "RMB Counterfeit Banknote Identifier" has been implemented since July 1, 1998. "General Technical Conditions for Anti-Counterfeiting Holographic Products", "Security and Anti-Counterfeiting Part One: Paper for Securities and Documents", "Part One of Anti-Counterfeiting Ink: Technical Conditions for Ultraviolet Excited Fluorescent Ink (Offset, Letterpress Printing)", "Specifications for Production and Management of Anti-Counterfeiting Printing Products" and "Anti-Counterfeiting Technical Terminology" and other five anti-counterfeiting standards, which were implemented as recommended national standards on May 1, 1998.
The "General Technical Conditions for Anti-Counterfeiting Holographic Products" stipulates the classification of anti-counterfeiting holographic technology, anti-counterfeiting strength, product technical requirements and safety measures; security and anti-counterfeiting paper standards are mainly used for printing securities, checks, stocks and certificates. ; Anti-counterfeiting ink standards stipulate the technical requirements for UV-excited fluorescent inks.
The implementation of the series of anti-counterfeiting standards is very beneficial to suppressing the social circulation of counterfeit RMB and counterfeit securities, protecting the interests of the people, and stabilizing the financial order; the five recommended anti-counterfeiting standards provide technology for regulating the development of the anti-counterfeiting industry. Foundation and guarantee.
As we all know, it is difficult for any low-tech or single anti-counterfeiting technology and product to effectively play an anti-counterfeiting role. The higher the level of manufacturing anti-counterfeiting products and the more difficult and complex the technology, the greater the difficulty of counterfeiting, and therefore, the better the anti-counterfeiting effect.
Based on this reality, many anti-counterfeiting product manufacturers continue to improve, perfect, and update their technologies and products. At present, they have developed laser holography, one-time use, invisible encryption, multi-color reconstruction, micro-secret marking, dynamic rotation, and orthogonal imaging. , UV fluorescent and color-changing ink and other anti-counterfeiting technologies, thus enhancing the anti-counterfeiting function of the product.
