The traditional anti-fake techniques are usually useless because they are too simple to prevent from being reproduced. Lables and packing boxes made by 3D lenticular stereotropic and flipping products can never be reproduced by electronic color scanners like the ordinary printed matters, because they are encrypted by optic refraction data. They can be used for anti-fake labels of cigarette, wine, drink, cosmetic, apparel & fashion, drudgery, etc. Some experts predict that 3D brand labels will become the main method of anti-fake ones.
