Presto Scuff Resistance Tester rubs two printed surfaces against each other (face-to-face) in the same plane, at the same speed (60 rpm), under a constant rubbing pressure. The rub test equipment can be used in Paper & Packaging industries to evaluate color transfer from printed or coated surfaces during rubbing.
The sample is attached to the base of the tester with the printed side up. A 2 psi test weight is attached to the sample and placed in position over the sample so that the printed sides are face to face. (Ensure use of customer specified material in place of the sample where required by customer). The tester is pre-set for the number of strokes (typically 100 cycles) and the machine is started as per the customer specification. After the required number of strokes, the samples is examined for any signs of ink transfer or scuffing.
