At present, there are two kinds of infrared excitation inks, infrared red and infrared green, and there are some infrared excitation inks of different colors, such as red, green, blue, purple, etc. Infrared excitation ink is an anti-counterfeiting ink developed by adding infrared light-emitting materials to corresponding linking materials through a special process. It is colorless in appearance and emits visible light after being excited by 980nm infrared light. .

Thermochromic ink is also called thermochromic ink, heat sensitive ink or temperature display ink.

The basic principle and process of offset printing Offset printing is referred to as offset printing. The printing method of offset printing is to transfer the ink dipped on the rubber surface to the paper surface through a roller-type rubber stamp. Offset printing requires less ink and molds are less expensive to manufacture than gravure. In addition, since the offset printing surface is flat and there is no concave pattern, the pattern and pattern on the printed paper surface are also flat, there is no three-dimensional sense, and the anti-counterfeiting property is poor. Now let's understand the basic principles and processes of offset printing.

UV ink is also called UV-curable ink, which uses ultraviolet radiation of a certain wavelength to instantly turn liquid ink into a solid state through photochemical reaction. The viscosity of flexo UV inks ranges from 250 to 2000cP (25°C), which is much smaller than that of offset UV inks. At present, UV ink has entered a mature stage, and is recognized by the world as a pollution-free ink variety, and its safety has been recognized by the US Environmental Protection Agency. Flexo UV inks are general-purpose and can be used when printing various substrates such as plastic, aluminum foil, and paper. The printing quality of flexo UV ink is better than that of water-based ink and alcohol-soluble ink, so its development and application have been paid attention to by all aspects.
