The Rub Scuff Tester is a quality control instrument used to evaluate the resistance of printed, coated, or laminated surfaces to rubbing and scuffing. It simulates the wear that occurs during handling, transportation, and storage by applying controlled rubbing motion between test surfaces. The tester helps assess ink adhesion, coating durability, and surface finish performance. Widely used in printing, packaging, paper, and label industries, it provides accurate and repeatable results for maintaining product quality and appearance.
