Spectral Properties and Rheology Behavior of Colorless Fluorescent Inks Used for Screen Printing

Colorless fluorescent ink has certain anti-counterfeiting function. In this paper, fluorescence curve and spectral properties of the fluorescent ink with colors of fluorescent red, fluorescent blue and fluorescent green used for screen printing are tested. Besides, rheological properties of fluorescent inks such as viscosity and thixotropic behavior are shown in the paper.
