In the realm of printing, varnish is a special coating applied to your printed materials, either during the printing process or afterwards. It serves a dual purpose: not only does it enhance the visual appeal of the printed item, but it also provides protection against scuffs, scratches, and damage from moisture or chemicals. There are several types of varnish used in printing, each with its own unique set of properties and applications. Now, let‘s explore these in detail.
Varnish is typically composed of a resin, a drying oil, a solvent, and sometimes a thinner. The resin, which forms the ‘body‘ of the varnish, combines with the drying oil to create a hard, glossy film. The solvent is used to adjust the thickness of the varnish for easier application, while the thinner is used to clean up any excess varnish.
