Among the various anti-counterfeiting technologies currently used, such as digital anti-counterfeiting, ink anti-counterfeiting, and optical anti-counterfeiting, paper anti-counterfeiting methods are relatively simple and applicable, and are gradually favored by many manufacturers, providing a broad market for anti-counterfeiting paper products.
Filmless holographic dark security paper
Quantitative can be divided into 50 ~ 350gm 2, no film, easily degradable, anti-counterfeiting pattern adopts implicit design, the surface gloss of the paper exceeds aluminum foil paper, PET, polyester poly aluminum film mirror paper, good printing adaptability, coating The pattern is resistant to acid, alkali, gasoline and alcohol, and the scrap rate and printing difficulty are much lower than aluminum foil paper and mirror paper.
Magnetic security paper
There are obvious magnetic patterns in the finished paper, and magnetic material powder is added to the pulp. When the pulp and magnetic powder are implanted into the magnetic security paper according to the shape of the magnetic plate pattern, the magnetic powder should pass through a 200 mesh sieve and should also be dyed.
Super ion media special paper
The paper is a fourth-generation anti-counterfeit product that uses a large-scale heavy ion accelerator of nuclear physics equipment controlled by the state, which combines ion micropore technology and papermaking technology. The heavy ion accelerator is controlled by the state, and no other equipment can be used. Reached its anti-counterfeiting technical indicators, so fundamentally eliminate fraud.
Textured paper
Sprinkle colored fibers in the white pulp, causing the naked eye to see the texture paper with a clear texture pattern, and then print it into an anti-counterfeit label, and store the texture image of the label in a special computer anti-counterfeiting system database. After labeling, customers can access the database via telephone, fax machine or the Internet to check the physical texture of the label and identify the authenticity of the product.
Add fluorescent fiber paper
The fluorescent material is dyed on the chemical fiber carrier, and the fluorescent fiber is made into fluorescent fiber paper according to a certain ratio. The surface looks the same as ordinary paper, but as long as it is illuminated by the purple light on the authentication, the fluorescence added into the paper The fiber immediately appears blue, and this technique is often used in the production of stamp paper.
Laser printed anti-counterfeiting special paper
Special anti-counterfeiting properties are provided by coating with a color-increasing adhesive. This special coated paper decoration with color-increasing patterns is dissolved in paper after laser printing and will not disappear due to friction, scratches, etc.
Thermal security paper
This kind of anti-counterfeiting paper can identify the authenticity only by the touch of a finger without the help of special instruments and equipment. The main reason is that an anti-counterfeiting filament called "Thermotext" is implanted in the paper. Cover text or patterns. When the temperature is high, the text or patterns will appear when the cover fails, and will return to the original after cooling.
Paper with watermark secret
The non-aqueous liquid composition containing the thermosetting resin and the heating agent is brought into contact with a certain size solution and cured, so that the watermarked or patterned part of the paper becomes less transparent than other parts. This is a commonly used anti-counterfeiting technology in banknote paper.
Color fiber security paper
The processing method of this kind of paper is more convenient than the use of watermark rollers. Various brightly colored fiber yarns are used. The color is generally more than two colors. The fibers are cotton, hemp, natural fibers or polypropylene, acrylic and other chemical fibers. Just add it to the box. Due to the relatively simple production process, this technology is currently used more, such as banknotes, various brand cigarette packaging, etc.
