TAPPI T830

Test Materials: TAPPI T830 evaluates the scuffing or rubbing resistance of ink on container board and corrugated board, typically using printed ink on these substrates.
Test Process: A rubber or fabric-covered wheel rubs over the inked surface under specified pressure and speed. The number of rubs is recorded until visible damage occurs.
Test Result Interpretation: The results are based on ink removal or damage. Greater resistance to rubbing is shown by minimal ink loss, while lower resistance shows significant damage or ink removal.
