Ink Rub Tester

THE TESTING DEVICE FOR UV CURING

The testing device for UV curing The IRT (Ink Rub Tester) from IST METZ facilitates the simple and repeated testing of the polymerisation in UV inks and varnishes. Here, a solvent is applied (e.g. acetone, MEK or IPA) and the number of double strokes required for penetration of the layer is set. Measured is the resistance of the ink or varnish film to the solvent. This resistance serves as a measurement for the degree of cure.
