A finishing step in which a clear varnish is applied to the surface of a printed sheet in order to create a glossy finish. The varnish is usually applied on the printing press. See also FINISH; FINISHING OPERATIONS; GLOSS; VARNISH
As a final step, negatives and prints are often coated with a shellac- or resin-based liquid that provides a smooth appearance and an extra layer to protect against scratches or other injury. Varnishes dry relatively quickly, producing a hard finish. To help reduce processing time, before exposure photographic papers can be coated on both sides with a plastic material similar to varnish. "Supercoats" were introduced around the late 1960s.
