Scuff Tester

This equipment is intended to evaluate the rub proofness of prints on paper or board. It can also be used to measure evaluate colour transfer from printed coated surface during rubbing. The application can be extended for measurement of abrasion resistance of some plastic materials aluminum foils.
Principle :
in this machine, 2 samples of the same substrate are rubbed against each other in the same plane, under a constant pressure of 2 p.s.i and at a fixed speed of 60 rpm. The number of rubs are recorded using a non-contact type digital counter.
inference :
this machine works as a great comparator of the variations in print quality between various batchesor various suppliers higher rub resistance = better print quality. Lower rub resistance = poor print quality.
