The Rub Proof Tester is used to evaluate the ink transfer from printed / coated materials from rubbing. Three dead loads are included enabling the user to place one on top of the upper disc to achieve a known pressure. The sample holders are manufactured from stainless steel to enable dry or wet rubs. An interlock on the front door reduces access during a test and prevents particles from being blown out of the working area. Digital cycle counter stops the test at the preset value.
