Rules reveal holographic anti-counterfeit labels

The distinguishing feature of this type of logo is that the logo can be clearly displayed after the logo is opened. The retention layer shows the aluminum film Yang character, and the uncovered layer shows the hollowed out Yin characters. The yin and yang are the same, the content is the same, the size is the same, and the resolution of exposing the graphic and text can be as high as 200dPi. It has the advantages of one-time use, identification convenience and counterfeiting difficulty, and is very suitable for sealing type anti-counterfeiting labels. In addition, this type of label is the carrier with the largest information capacity per unit area and can display four kinds of graphic information that do not interfere with each other. The first layer, the surface of the printing graphics (security ink printing); the second layer, the aluminum layer of the hologram; the third layer, the exposed layer of graphics; the fourth layer, the bottom of the printing graphics. The partial hollow-type holographic anti-counterfeit labels are printed on the surface of the embossed film aluminum gravure printing anti-corrosion techniques. After etching, the aluminum on the aluminum-plated film can be hollowed out regularly, and the hollow precision can be more than 1 75dPi. The advantage of this method is to use the etching process and precision to improve the security of the logo.
