With the development of digital printing, digital anti-copy technology is also in constant development. At present, Fluorescent inkjet ink is one of the digital anti-copy technologies that used widely abroad. Fluorescent inkjet ink is composed of solvent, resin, phosphor, assistant agent and so on, and resin is the main component in the fluorescent inkjet ink, which has an important effect on the luminescent property and various physical properties. In order to research and develop the fluorescent inkjet ink, fluorescent inkjet ink samples had been prepared by changing the content and type of resin, and the several important properties which include luminescent property, viscosity, surface tension etc were tested, and then the optimal content and type were determined. The effect of resins on the significant properties of the fluorescent inkjet ink had been studied. At last, the prints that obtained by using ink-jet press and red Fluorescent Inkjet Ink have a good print quality.
