Inks Used For shrink applications have to be capable of going above and beyond the call of ordinary ink duties. Shrink inks have to adhere well to film substrates, hold color despite heat, maintain a certain coefficient of friction (COF), and—most importantly—shrink. "[Shrink inks] need to have superior adhesion, flexibility, be fairly heat resistant because heat is involved in the process, and [be made with] pigments that won't change color or fade with heat application," said Ed Dedman, market development manager for SICPA North America. "They need to be better performers all-around than other inks." According to Mike Buystedt, Akzo Nobel Inks director of market development, "Currently four chemistries exist for shrink applications—solvent-based, water-based, UV cationic, and UV free radical. Solvent-based technology boasts the highest market demand at this time; next in line would be water-based."
