The application of stereo card in anti-counterfeiting, 3D stereo is a combination of digital technology and traditional printing and output technology, with a series of stereo images to form a picture, picture surface covered by a layer of grating. The purpose of the grating is to direct light from any point in the image in a specific direction to the left and right eyes. According to the research, we human eyes watching a 3 d object, eye level as the two separated in two different position, the observed object image is different, they exist between an aberration, because of the existence of the aberration by the human brain, we can feel the depth of a three-dimensional world stereo change, this is the principle of stereo vision. In this way, people do not need to train, do not need to use instruments and other tools, put the picture directly in front of their eyes can clearly feel the wonderful fun of three-dimensional pictures. If the image is composed of a series of continuous animations, then when the eyes move up and down or turn the grating up and down, the Angle between the eyes and the grating will change, and we will see one continuous image after another, that is, we will see an animation or the effect of changing the painting.

Stereo printing USES optical encryption comprehensive anti - counterfeiting method. The past anti - counterfeiting technology, because the technology is too single, so difficult to prevent. The three-dimensional anti-counterfeiting trademark is made of optical refraction data encryption, which can not be reproduced by electronic color separators like ordinary prints. This technology can be applied to the anti-counterfeiting labels of tobacco, alcohol, beverage, cosmetics, clothing, pharmaceuticals and other products. Bold prediction of experts: 3-5 years three-dimensional trademark must become the main anti-counterfeiting way.

Just do the following to ensure that your label or package is not copied:

First, use the original picture, and ensure that it is the only plane picture;

2. Three-dimensional design of original pictures;

Third, the plane column mirror (grating) material as the medium, let it display the three-dimensional space screen;

Four, control the original picture, do not let it into the market in the form of plane;

Five, good identification publicity, label or packaging three-dimensional pattern into shopping malls and public places for publicity, is conducive to consumer identification, brand publicity has a good role in promoting;

No one can copy your packaging or label.
