Coatings are an essential component of packaging design, protecting packaging from external impact such as abrasion, scratches and indentations. It is frequently used to highlight special parts of the packaging or enhance the look, touch and feel of your products on-shelf to emphasise their quality. The most commonly used types of coatings, particularly in offset printing, are print coatings, water-based coatings, UV coatings and special coatings. Varnishes are normally applied in an inline process while printing via a coating section via rollers.
