In order to obtain fluorescence inkjet ink with high fluorescence intensity and inapparent attenuation, ethanol and triethanolamine were chosen as desiccant and pH regulator respectively to prepare ink samples. The influences of ethanol and triethanolamine contents on fluorescence intensity were discussed. Different types and contents of ultraviolet absorbent were chosen to prepare ink samples respectively. Effects of type and content of ultraviolet absorbent on the fluorescence intensity and attenuation were discussed. The results showed that with increase of ethanol content and decrease of triethanolamine content, fluorescence intensity enhances significantly; ultraviolet absorbent UV-7292 has a little effect on fluorescence intensity and it can improve light resistance of the printing ink. On the premise of meeting other performances, when the content of ethanol, triethanolamine and ultraviolet absorber UV-7292 was 15%, 0. 6%, and 0. 5% respectively, UV fluorescent inkjet ink shows best luminescence property.
