Editor’s Note: “UV Flexographic Inks: Correlation Between Rheology and Press Performance” was presented at the National Printing Ink Research Institute’s (NPIRI) 45th Annual Technical Conference in Scottsdale, AZ in October 2001. The secret to developing a good printing UV flexographic (flexo) ink is related to pigment wetting and the rheology of the formulated system. Ultimately, the goal in formulating UV flexographic inks is to have a system that is very low in viscosity and remains low in v...
