Zusammenfassung:A system and a method for providing a film having a matte finish. The system includes means for providing a coated substrate, the coated substrate comprising a first coatable material applied to a substrate, the coatable material forming a first major surface of the coated substrate; means for changing the viscosity of the first coatable material from a first viscosity to a second viscosity; a face-side roller having an outer surface positioned to contact the first major surface of the coated substrate to impart a matte finish thereon; and optionally, means for hardening the first coatable material. The method of the invention includes the steps of (1) providing a coated substrate comprising a coatable material disposed on a substrate, the coatable material providing a first major surface of the coated substrate; (2) changing the viscosity of the coatable material from the initial viscosity to a second viscosity; (3) contacting the first major surface of the coated substrate with at least one face-side roller to impart a matte finish; and (4) optionally, hardening the coatable material to provide the film.
