Evaluation of the Gavarti Comprehensive Abrasion Tester (CAT)

The Gavarti Comprehensive Abrasion Tester (CAT) is a relatively new instrument for the graphic arts industry. While there have been several published articles concerning its ability to duplicate damage found in the field, this paper examines the operating variables of the CAT and compares it to the Sutherland Rub Tester. Much of this work was done using folding carton type stock. Tests were conducted in accordance with manufacturers specifications. This testing led to the development of standard test parameters for the CAT. In addition, a method of quantifying rub resistance is presented. This work showed that the Sutherland Rub Tester can be improved by using a Gavarti Standard Receptor.
