Laser anti-counterfeit technology including laser holographic security label, encrypted laser holographic image marking and laser lithography technology in three aspects.

Holographic anti-counterfeiting technology includes: 1 the conventional holographic anti-counterfeiting technology, 2 multi-channel holographic anti-counterfeiting technology, 3 stealth encryption technology, 4.360 °computer lattice holographic technology, 5 double holographic technology, 6 fluorescent encrypted holographic technology, 7 dynamic coding anti-counterfeiting technology, 8 telephone code anti-counterfeiting technology, nuclear microporous anti-counterfeit technology and gene technology, and has image clear, colorful, three-dimensional sense of strong, disposable characters. Multi channel holographic anti-counterfeit identification in the rotation, will see the logo in the same location on different patterns. Stealth encryption technology will be produced in the encryption design the logo of a position, in laser-reproduction may be seen under the encrypted pattern. 360 °computer lattice holographic technology in image 360 degrees viewing range will appear radially, ring, spiral spot combination and transformation, dynamic strong. Double holographic technology can make holographic label opened, can see printed pattern and text layer second security, double insurance security. Fluorescent encrypted holographic technology principle and its fluorescence encryption principle. Dynamic code is placed in front of the trademarks, slowly rotate trademark there will be continuous action pattern. Telephone code anti-counterfeit mark is composed of laser anti-counterfeiting technology and the telephone code anti-counterfeiting technology of combining production, by querying the database can check the authenticity of the unification center. Nuclear microporous anti-counterfeit identification by laser anti-counterfeit technology and nuclear microporous anti-counterfeit technology, only one pen can distinguish authenticity. Security is in the identification of genes into gene gum, through a special equipment for testing.

Is a commonly used laser rainbow embossed holographic anti-counterfeiting technology, it is the application of laser rainbow hologram plate technology and embossing technology, products produced by a visual graphic information.

Rainbow holographic image is generally a holographic image as an object, through a series of procedures made of rainbow hologram. As in the use of photoresist etching agent for photographic film to replace the ordinary photo shoot of the hologram, the exposure processing, namely a relief type phase holograms, i.e. making rainbow hologram master. Master surface filled with uneven interference fringes, the fineness of up to more than a thousand per mm. These relief shape stripes recorded a photographed object light intensity and phase information, realization of the holographic recording. Then with vacuum plating or chemical plating method, the master surface coated with a layer of thin metal film, and then the appropriate thickness of the electroplated nickel or other metal, make a good mechanical properties of the molded metal plate. The board is arranged in a stamping press, hot press polyester plastic film, the relief hologram embossing on the film, the last in the film vacuum evaporation a layer of aluminum film, in order to enhance reflectivity. The aluminum film plating or coating protection cover layer, is formed in holographic images, i.e. opaque laser embossed holographic map. This hologram can observe daylight sunlight, each one of the wavelengths of light are pictures of the interference fringes by diffraction, due to different diffraction angle, the different view, a different color reproduction image.

Since the hologram color combination is random code, even if the same equipment is difficult to produce exactly the same holographic mother plate, therefore the rainbow holographic image has been widely used in the production of anti-counterfeit labels. Can also be the hologram directly transfer to paper products, is now widely used in the ticket, the trademark and credit card.

Embossed holographic label color has a single rainbow, a variety of rainbow color, true color and black and white ( ICR ) 4, its image is two-dimensional, three-dimensional, multiple and dynamic imaging.

Laser molding holographic holographic imaging technology is different, can be divided into classic, pulse laser embossed holographic label and molded of synthetic resin, multiple image laser molding, dynamic compression, dynamic grating holographic molding, molded, invisible ink encrypted laser holographic molding etc..

In recent years again bronzing hologram and through type hologram come out, they are in ordinary rainbow hologram based on innovation. The transflective type hologram is polyester film aluminum layer is made into a dot shape and control the dot density, in the reproducing light so that the metal mesh point light reflection, in non metal mesh point forming the transmission of light, and adjust the transmission and reflection ratio, so that through the hologram can see diagram under cover in the text, it is also known as X-ray hologram.

The development of anti-counterfeiting technology, color hologram, synthetic hologram, the hologram ( password using a laser pen can be read out the map information ), come one after another. The laser holographic technique after treatment with anti-counterfeit function of new packaging materials and higher technical level of holographic image identification technology, has better security function.

Using holographic printing technology to make the label that prevent bogus, attached to the surface of the packaging is currently the most popular anti-counterfeiting measures. Holographic image because of the integration of the laser, precision machinery and physics chemistry and other disciplines of the latest achievements, with high technical content. For most small batch forger, a full set of manufacturing techniques and manufacturing equipment purchase difficult, so this technology is remarkable.

Laser holographic anti-counterfeiting technology development history [ ]:

After decades of development, laser holographic anti-counterfeiting products from the original holographic anti-counterfeiting label upgrade stage by stage for the development of the second generation, third generation and fourth generation of laser anti-counterfeiting technology.

The first generation of laser anti-counterfeiting technology is laser molding hologram anti-fake mark.

The hologram is by American scientist Berg ( MJ ·Buerger ) by X ray shooting crystal atomic structure pictures when found, and Gabor ( D ·Gaber ) with the establishment of the holographic theory : the use of the principle of two-beam interference, the object and another object light and the reference beam coherent light beam ( ) to produce an interference pattern can be put up, thereby phase "merge" use photographic film can be recorded at the same time the phase and amplitude,<
