Features of infrared anti-counterfeiting technology:

Infrared anti-counterfeiting technology utilizes the infrared band that is not visible to humans. And the realization of invisible anti-counterfeiting technology. Infrared anti-counterfeiting mainly relies on the principle that printing with infrared ink is invisible under daily light sources, usually white or colorless, and printing on paper or plastic film does not show color or is invisible to the naked eye, and print anti-counterfeiting labels. The anti-counterfeiting mark is not visible, so counterfeiters cannot copy the label. So as to achieve the practical effect of anti-counterfeiting.

Advantages of infrared anti-counterfeiting technology:

1. Good invisibility and difficult to be copied.

2. It can be applied to automatic intelligent detection technology.

3, the detection is simple.

Infrared anti-counterfeiting technology composition:

Infrared ink + encoding encryption technology + infrared decoding technology.

1. Infrared ink: use special substances to test the absorption performance of infrared light. The dye (or pigment) in the ink does not absorb visible light or has weak absorption, but can fully absorb infrared light. It is mainly used for optical character readers. read;

2. One is infrared fluorescent ink, which mainly uses the fluorescence of the substance. The pigment in the ink can be excited by infrared light and emit infrared fluorescence with a longer wavelength, which can be detected.

3. Invisible infrared ink contains special substances that can absorb 700-1500nm wavelength light and excite visible fluorescence. Its anti-counterfeiting feature is mainly that it will display invisible graphics or light when it is identified by infrared rays. Due to the wide range of infrared absorption of special substances, Therefore, the infrared detector should have a certain sensitivity to accurately distinguish its authenticity. It is mainly used in anti-counterfeiting printing such as bills and securities.

The advantages and development of infrared anti-counterfeiting technology:

From the user’s point of view, the growing scale shows that infrared anti-counterfeiting technology will become the mainstream in the future. The rapid progress of nanotechnology has also brought a steady stream of impetus to the development of a new generation of infrared anti-counterfeiting technology. Scientists even said that in the future, humans will create invisible clothes. Refracting the light source behind the infrared 3D particles can make humans invisible.
