Sutherland type rub tester for ink rub test is a new type testing machine designed to measure scuffing or rubbing resistance. Several tests can be performed including dry rub (the amount of transfer of ink from one dry surface to another), wet rub (the amount of transfer of ink from wetted surface to another). It is professionally applicable to the abrasion resistance test of surface coating layers of printed materials, e.g. ink layer or photosensitive (PS) coating. This instrument can effectively analyze the problems of poor abrasion resistance, ink layer falling off, lower printable force, and bad hardness of coating layers of printed materials.
