Study on Preparation and Properties of Fluorescent Offset Printing Ink

Abstract:

The ultraviolet (UV) fluorescent anti-counterfeiting offset printing ink, which can emit visible light (400-800 nm) under the excitation of ultraviolet light (200-400 nm), has been extensively adopted in the modern printing technology. In this paper, we used the red-emitting phosphor BaCaBO3F: Eu3+, Li+ as the fluorescent pigment for printing ink and investigated the influence on additive amount of the luminescence properties of fluorescent ink in order to determine a more ideal ratio of fluorescent ink .Besides, the shear viscosity, thixotropy, visco-elasticity and the temperature dependence of viscosity according to the rheology theory and rheological technique were also studied, and finally the valuable parameters and patterns were successfully obtained.
