Brief introduction and simple identification metho

  • Detail

In recent years, due to the proliferation of fake and shoddy goods, the use of anti-counterfeiting technology has become increasingly prominent in identifying and preventing fake and shoddy goods. Printing anti-counterfeiting marks on their own products has become an effective measure for famous brand manufacturers and enterprises producing famous and high-quality products to protect themselves. At present, there are hundreds of products with anti-counterfeiting marks in the Chinese market, such as Xiafei cosmetics, Red Star Erguotou Wine, computer floppy disks produced by 3M company, etc

anti counterfeiting labels generally include the following:

1. reactive SK temperature control anti counterfeiting mark: as long as the trademark is heated slightly, the anti-counterfeiting color will fade immediately, showing the production mark of the anti-counterfeiting manufacturer; After cooling, the anti-counterfeiting color is quickly restored and the anti-counterfeiting mark is covered again

2. fluorescent anti-counterfeiting mark: illuminated by a special anti-counterfeiting fluorescent lamp, the mark printed with anti-counterfeiting fluorescent ink will shine, showing bright red, orange, yellow green or green fluorescence, with high fluorescence intensity and good printing adaptability

3. stealth technology anti-counterfeiting in order to give full play to the respective advantages of enterprises and scientific research institutions: according to the principle of holographic anti-counterfeiting marking, a kind of hidden true flashing color changing anti-counterfeiting marking is directly made on the top surface of the metal bottle cap. This kind of mark can reflect a specific pattern or glyph under the sunlight or spotlight

4. laser holographic anti-counterfeiting mark: according to the principle of laser interference, the 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 not easy to copy, so it should be advocated and popularized

5. photosensitive and temperature sensitive double anti-counterfeiting mark: a double anti-counterfeiting mark composed of a base layer and a coating layer containing photosensitive and temperature sensitive respectively. The color of the selected photosensitive coating changes from light to dark rapidly within s under the natural light ultraviolet irradiation, and reversible reaction occurs; Temperature sensitive coating is a manufacturer specializing in the production of hydraulic universal testing machine in Shandong Sida high tech. when touching s with your finger at high temperature, the color changes from dark to light rapidly, resulting in reversible reaction. When using, consumers only need to gently press and hold the anti-counterfeiting mark on the commodity with their fingers, and they can change the color after 5S

two foreign anti-counterfeiting marks are introduced below

1. 3M reverse anti-counterfeiting label: 3M's original products are attached with watermark reflection labels. The identification method is as follows: hold a flashlight between two eyes and parallel to the eyes, the light source irradiates the label, the eye line of sight looks with the light source, and the label will reflect a shiny 3M watermark, which is true and false, and can not be forged

2. the "shape memory" anti-counterfeiting mark on the air conditioner of Mitsubishi Heavy Industries in Japan: use an electric hair dryer (hair dryer) to blow hot air s to the "anti-counterfeiting trademark of Mitsubishi Heavy Industries" pasted on the indoor/outdoor unit of the "Mitsubishi Heavy Industries Air Conditioner". After the trademark becomes soft, press it with your fingers to deform and wait for it to cool and harden. Blow hot air again to the deformed trademark to restore its original appearance. This method, called shape memory function identification, 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 compulsory national standard, the instrument for identifying counterfeit RMB banknotes has been implemented since july1,1998. Five anti-counterfeiting standards, including general technical conditions for anti-counterfeiting holographic products, safety anti-counterfeiting part I: paper for securities and certificates, anti-counterfeiting ink Part I: technical conditions for UV excited fluorescent ink (offset and relief printing), production management specifications for anti-counterfeiting printing products and anti-counterfeiting technical terms, were implemented as recommended national standards on may1,1998

general technical conditions for anti-counterfeiting holography to produce halo color products with clear black and white layers stipulates the classification, anti-counterfeiting strength, product technical requirements and safety measures of anti-counterfeiting holography; The security anti-counterfeiting paper standard is mainly used for printing securities, cheques, stocks and certificates; The anti-counterfeiting ink standard specifies the technical requirements for UV excited fluorescent ink

the implementation of the anti-counterfeiting series of standards is very beneficial to restraining the social circulation of fake RMB and fake securities, protecting people's interests and stabilizing the financial order; The five recommended anti-counterfeiting standards provide technical basis and guarantee for standardizing the development of anti-counterfeiting industry

as we all know, any low technology content or single anti-counterfeiting technology and product is difficult to play an effective anti-counterfeiting role. The higher the level of manufacturing anti-counterfeiting products, the more complex the technology, and the greater the difficulty of counterfeiting. Therefore, the better the anti-counterfeiting effect. Based on this reality, many anti-counterfeiting product manufacturers continue to improve, perfect and update their own technologies and products. At present, they have developed products with a variety of anti-counterfeiting technologies, such as laser holography, one-time use, invisible encryption, multi-color recombination, micro cryptogram, dynamic rotation, orthogonal imaging, UV fluorescence and color changing ink, so as to enhance the anti-counterfeiting function of the products
