UV Invisible ink
UV fluorescent ink is made by adding the corresponding visible fluorescent compound to the ink. Its anti-counterfeiting feature is: the printed matter is invisible under ordinary light, and it can emit gleaming fluorescence under ultraviolet light. There are invisible and tangible UV fluorescent inks. The special ink that is excited by ultraviolet light (200-400nm) to emit visible light (400-800nm) is called ultraviolet fluorescent ink. According to the excitation wavelength, it is divided into short wave and long wave. The excitation wavelength of 254nm is called short-wave ultraviolet fluorescent ink, and the excitation wavelength of 365nm is called long-wave ultraviolet fluorescent ink. According to the color change, it is divided into three types: colorless, colored, and discolored. Colorless can display red, yellow, green, Blue and other colors; colored can make the original color bright; color change can make one color into another color.
