Study on the Stability and Color Property of Fluorescent Ink-jet Ink

摘要

Fluorescent ink is mainly applied in traditional printing methods which can affect fluorescent emission of ink seriously. However, ink-jet printing-applied fluorescent ink extensively cannot prevent fluorescent emission of ink due to dot paralleling. Therefore, in this paper, the properties of fluorescent ink-jet ink were studied. The fluorescent stability is one of the important properties for fluorescent ink-jet ink, which can limit the storage of fluorescent ink. The additive can adjust the certain property of ink but can also influence ink's stability among the components of ink. The effect of triethanolamine and UV absorbent on ink's stability was studied in this paper. Presently, there is no perfect means to control the color of fluorescent ink, the white balance were processed by using fluorescent ink-jet ink with three primary colors red, green, and blue and printing device ESPON7600 with dot paralleling. The results showed that the optimal quantity of triethanolamine was 0.6 %, the UV absorbent UV-7282 had the less effect on ink's stability and white balance curve with high accuracy and almost unbiased color was determined.
