Ultraviolet-excited fluorescent anti-counterfeiting ink is an ink made of inorganic pigments or organic dyes that can be excited by ultraviolet light to display colors, called fluorescent inks (or invisible inks). Its manufacturing method is to add the pigment (dye) to a certain proportion of resin oil linking material, filler, stabilizer and desiccant, and process it with an ink-making three-roller mill.

Women's Day on March 8, 2023 is a fruitful day for Print Area.

Print Area supply different uv color change ink.Like:color to color,colorless to color,double wavelength one.

UV fluorescent inks are made by adding corresponding visible fluorescent compounds to the ink. Its anti-counterfeiting features are: the printed matter is invisible under ordinary light, and can emit glittering fluorescence under ultraviolet light. There are invisible and visible UV fluorescent inks. The special ink that emits visible light (400-800nm) is excited by ultraviolet light (200-400nm), which is called ultraviolet fluorescent ink. According to different excitation wavelengths, 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. Blue and other colors; colored can make the original color shine; discoloration can make one color into another color.
