2. Printing anti-counterfeiting trademarks, anti-counterfeiting certificates and bills.
3. Dual-card anti-counterfeiting trademark; There are four kinds of dual-card anti-counterfeiting trademarks: Moire stripe dual-card, nuclear track dual-card, polarized light dual-card, and random encrypted hidden graphics dual-card.
4. Graphic output laser anti-counterfeiting trademark; Using laser beam to form graphic anti-counterfeiting marks on the surface of the subject matter.
5. Nuclear micropore anti-counterfeiting trademark, namely nuclear track anti-counterfeiting. The imaging method of heavy ion generator or nuclear reactor (state-controlled equipment) irradiates organic thin films and causes ionization damage. Etching the formed track with strong alkali or strong acid to make it into micropores. Graphics and characters are composed of micropores. Its anti-counterfeiting feature is that under visible light, due to the diffraction and scattering of micropores, the visual effect observed by human eyes is white graphics and text. If there are water drops on it, the water will penetrate into the micropores and the pictures and texts will disappear. If coated with colored liquid, the colored liquid will penetrate into the micropores, wipe off the colored liquid on the surface, and present colored pictures and texts.
6. Expose anti-counterfeiting trademarks with pictures and texts;
7. Invisible graphic anti-counterfeiting trademark. Anti-counterfeiting trademarks are made of materials with anti-reflection characteristics, including flash angle image type, multi-dimensional flash angle type, reflective watermark type and so on.
8. Magnetic anti-counterfeiting trademarks. Anti-counterfeiting trademarks are printed with magnetic ink. For example, the information characteristics (such as code bar, code width and code distance) and magnetic characteristics (remanence ratio and coercivity ratio) of magnetic ink made of magnetic powder are coded by PS glue mixed printing and screen printing. Identification by hidden magnetic code discriminator (rapid magnetic measurement by impact induction, accurate testing of various characteristics of coded materials, and logical decoding).
9. Marking and distributing anti-counterfeiting trademarks. Anti-counterfeiting trademark is made of three-dimensional color fiber distribution characteristics, which is called texture distribution anti-counterfeiting mark. The anti-counterfeiting mark made by using the distribution characteristics of colored reflective particles and white raised microbubbles is called particle distribution anti-counterfeiting trademark. The originality of this logo belongs to our country, and the uniqueness and imitation difficulty of the logo are good.
10. Stamp the anti-counterfeiting trademark. The anti-counterfeiting trademark is covered with unique corresponding digital or graphic information through the covering layer. Logo can be divided into scraping and uncovering. If the cover is removed, it should not be used again. The most common anti-counterfeiting trademarks are scraping and uncovering codes;
1 1. Original light carving anti-counterfeiting trademark. The anti-counterfeiting trademark is made by high-resolution lithography technology, and a hologram with grating spacing less than or equal to 0.4μm is formed on the film, and the zero-order diffraction is the reflection direction under oblique white light, forming a picture and text with equal inclination interference of the film. China's new identity card adopts this international top-level high-tech technology. It rotates 90 degrees along its own plane, and the color of the pattern "Great Wall" changes accordingly.
12. ultraviolet fluorescent anti-counterfeiting trademark. A special ink that emits visible light under ultraviolet irradiation is called ultraviolet fluorescent ink. Widely used in RMB, bank bills, tax bills, etc.
