Scuff Tester ( Rotary Rub Tester )

Scuff Tester (also known as the PATRA / PIRA Rub Tester), is an equipment to test printed substrates such as paper boards for resistance to scuffing / rubbing / smudging when 2 circular samples are rubbed against each other in a rotary motion, under a defined pressure, at a defined speed for a defined number of rubs.

High Rub Resistance = Good Quality Print

Suitable for : Printed Duplex Boards or any thick material in sheet form.

Confirms to : British Standards  BS-3110

Scuff Tester / Rotary Rub Tester              VXC Series

The Scuff Tester or Rotary Rub Tester is intended to evaluate the quality of printing on paper or paper board.

To evaluate Abrasion Resistance or Colour Transfer from printed / coated surface due to rubbing or scuffing action experienced by printed material during production, handling, or transportation.

This equipment is meant for semi-rigid substrates like Paper Board / Duplex Board but can also be used for measurement of abrasion resistance of thicker Plastic Films / Laminates / 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 – 4 p.s.i and at a fixed speed of 60 RPM.

Method of rubbing :         Rotary Rub (Circular Motion)

Confirms to :                       BS-3110 standards.
