Getting Better All the Time

Oligomers: Oligomers are binder components of UV and EB inks, which are especially helpful in binding inks to hard-to-adhere-to substrates like film.

Some oligomers also assist in the dispersion of ink pigments, Duncan said. "Some curable oligomers that are better at dispersing pigments are coming on the market," he said. "This will allow formulators more latitude to improve on-press lithographic performance of inks."
