coater
The part of a litho printing press that applies coatings to printed literature
coating
Special water-based coating applied to printed matter to protect literature from ink smudging or finger marking or to enhance appearance. The main types are sealer, gloss, matt and silk. Coatings are commonly used on matt or silk-coated paper as these are more prone to smudging than gloss-coated paper. The main difference between a varnish and a coating is that coatings are faster drying and therefore jobs can be turned around quicker. They tend to be more scuff resistant than varnishes and there is also less risk of yellowing paper. However, oil-based varnishes are better if specific areas of a document need to be coated (spot varnish)
