The development of label printing technology, leading to more and more serious situation of production homogenization, a lot of fake start to counterfeit various products as brand-name manufacturers, had seriously violated the interests of enterprises, and even cause the crisis to the enterprise’s brand, this will let consumers lose trust in enterprises. According to WTO statistics, the world economics had been affected by fake and shoddy products market reached US$300 billion, the annual turnover of fake and shoddy products has accounted for 10% of world trade. In our country, the scale of fake and shoddy products is 300-400 billion RMB, especially in the fields of tobacco, liquor, food, cosmetics and so on, these had become the hardest hit area of fake and shoddy commodities. Enterprises in order to reduce these hazards, have introduced a variety of anti-counterfeiting sticker printing technology. Of course, wherever there is demand, there is market. Fake and shoddy products are rampant and various anti-counterfeiting techniques have appeared on the market. In the traditional anti-counterfeiting technology, the physical anti-counterfeiting occupies the dominant market. Approximately, the physical anti-counterfeiting technology has the following ways:

1.    temperature control anti-counterfeiting          

So as the anti-fake label is slightly heated, the anti-counterfeit color will fade, and then the production mark of the anti-counterfeiting manufacturer is displayed, but the color will be restored after the temperature is lowered, and the anti-counterfeit label can be used many times.          

2.    fluorescent anti-counterfeiting          

It is illuminated by a special anti-fake fluorescent lamp, with lights or sunlight, it will appear very beautiful color, because of its high fluorescence intensity, printing adaptability is also very good.          

3.  Stealth technology anti-counterfeiting          

According to the principle of the laser anti-fake mark, it can reflect a specific pattern or glyph under the irradiation of the sunlight. It is similar to the anti-counterfeiting system in RMB bank note.
