Several Common Information Anti-counterfeiting Printing Technologies for Product Packaging (Continued)

The encoding method and method of raster points are determined according to the specific design of the pattern, and others are extremely difficult to imitate. For example, with a laser pattern with a resolution of 300 dpi, there are nearly 14,000 grating points in a square centimeter area. Apart from the design of the pattern, if you want to imitate the same visual effect pattern, you must request this. The coding of 40000 raster points must be consistent with the original pattern. Only the technical difficulty of this point is enough to deter the criminals. At present, the computer software of Microsoft Corporation and the computer chips of Intel Corporation of the United States all use this laser logo for anti-counterfeiting.
2 In the aspect of pattern design, computer fractal pattern technology is combined. This fractal pattern is the input of relevant data on a programmed computer program, and an algorithm that produces a pattern that does not exist but is very strange and decorative in nature. This pattern can be made into a part or the whole of a laser mark by using a dot-matrix laser holographic technology, or it can be superimposed on the original registered trademark of the manufacturer as a background image. The laser mark thus made has excellent anti-counterfeiting performance. Keeping these data is not leaking, and no one can produce the same or similar fractal pattern.

3 In addition, unlike ordinary printing, a laser pattern (especially a fractal pattern) made with a dot-matrix laser holographic technique is determined by its characteristics and cannot be copied by photographing, copying, or computer scanning.

According to reports, there are also color holograms, synthetic holograms, and password holograms (in which information can be read out with a laser pen), and edible holograms can be used for tablet anti-counterfeiting.

4, heavy ion imaging information technology. This is a high-tech heavy ion imaging technology introduced by Beijing Super Energy Technology Co., Ltd. Using 5-10mm transparent plastic film as raw material, heavy ion energy generated by heavy ion generator accelerates heavy ions to energy of 80 MeV or more through an accelerator. An imaging mold is mounted on the heavy ion channel so that the imaged heavy ion beam is irradiated onto the plastic film (time is 0.5-2ms). After being processed by a special process, an anti-counterfeiting logo pattern composed of 1'105/cm permeated micropores can be formed on the plastic film. This pattern can be designed according to user requirements. This pattern is colorless before it is detected. During the test, the protective film attached on the surface is torn first, and then painted with a colored pen or pen in the pattern area of ​​the film, and then wiped clean by hand, leaving behind the corresponding color anti-counterfeiting pattern, the non-pattern area is not penetrated colour.

The main equipment of the super anti-counterfeiting label is the only national defense special control equipment in China—heavy ion accelerator, which has exclusiveness, and its products cannot be counterfeited. The manufactured anti-counterfeiting labels are not afraid of boiling water, resistant to various inorganic acids, salts, and alcohols, and are also resistant to low-concentration lye at room temperature and can be used for long-term preservation. Colorful identification is available anytime, anywhere.
