On the Post-cure Case (UV Inks)

WHAT is (and what isn't) post-cure?

Though used throughout the industry, the term "post-cure," in many cases, is technically a misnomer. Rob Stendahl, corporate technical support supervisor for Akzo Nobel, clarifies: "Post cure only takes place with cationic UV-curable inks. The more common type of UV inks is cured through a UV-induced free radical polymerization process and has no post cure at all. What many people refer to as post cure is simply the relaxation of the high level of stresses built up into the ink film during the materials' incredibly fast cure process."
