A hologram is commonly used for anti-counterfeiting in the market. It is a special printing technique with the concept of using light diffraction (a light field or laser light) to form an image. However, the difficulties of this technique are relatively easy as the barrier of producing hologram is getting lower.

Therefore, we have upgraded the traditional hologram into a dual-color precise hologram. It is created by two different lasers encoded holographic and imprint precisely within a predefined area. This process can only be produced by specialized devices with advanced process technology to achieve the purpose of imitation prevention and easy identification.
