Aqueous coating is a popular type of clear top coat applied to printed surfaces. It helps protect the ink and paper against scuffs, abrasions and smudges, especially for silk papers.

In addition to protection, Aqueous Coating enhances the appearance of printed pieces by providing some sheen, which in turn helps make colours appear more vivid.

As the name implies, Aqueous Coating is water-based. This makes it more economical and environmentally friendly than many traditional varnishes. Aqueous coating is also less prone to cracking.
