IGT tester

Purpose
IGT is a measurement of the surface strength of the paper.
Principle
A tacky ink is applied to sample of the paper at an increasing speed. As the speed increases the peeling force applied to the paper also increases and the speed at which the fibers begin to be pulled from the sheet is recorded as the IGT. A high IGT (>300) indicates a strong surface strength suitable for demanding offset applications.
