In order to improve the fluorescence lifetime of fluorescent ink, the impacts of illumination time and light intensity on fluorescence intensity attenuation were discussed. Different contents of fluorescent dye were chosen to prepare ink samples and the effect about content of fluorescent dye on fluorescence intensity attenuation was discussed. Different types and contents of UV absorber were chosen to prepare samples respectively and the effect of types and contents of UV absorber on fluorescence intensity attenuation was discussed. The experiments showed that the fluorescence intensity attenuation was significant with extension of light intensity and enlargement of illumination time; content of fluorescent dye had a significant influence on fluorescence intensity attenuation; UV absorber was conducive to improve light resistance of fluorescent inkjet ink, and its content had certain influence on fluorescence intensity attenuation. Fluorescence intensity attenuation was not obvious about the developed ink at the right intensity of fluorescence intensity and illumination time.
