The Sutherland type ink rub tester is an automated instrument for rub a test strip under specified pressure, speed and temperature over a print determining the resistance to abrasion of the print. Abrasion resistance is a critical property for printed materials. Damage due to abrasion can occur during transport, storage, handling or use, resulting in deterioration of the image and readability of the information.

The ink Rub tester allows comparison of the abrasion resistance of different materials under controlled conditions.
Weights for higher or lower forces as well as heated weights are available.
Rub resistance determines the suitability of printed matter, folding cartons, brochures, newspapers, and wrappers for further processing, mailing or other purposes. It is influenced by the properties and combinations of ink, substrate, spray powder, varnish and dampening liquid. Therefore, test of rub resistance is vital to printers, converters and manufacturers of inks and substrate.

Compact UV dryer for use with printability test equipment. 
Version with fixed curing power and variable speed.
Several light sources available.

The test pens contain, similar to the test inks, fluids of defined surface tension. The surface energy of the material to be checked is determined simply by applying a stroke of ink with the tip of the felt pen. The accuracy of the measurement is, like the one of the test inks, 1mN/m

The test inks are fluids of defined surface tension, which are available in bottles of 10, 100, 250 or 1000ml. The surface energy of a substrate is checked by simply applying the test ink to the surface. The accuracy of the measurement is 1mN/m.

Full width magnetic clamp allows precise sample positioning with secure grip, 12.7mm thick float glass platform large enough for direct A to B comparisons or evaluation of machine caused treatment variations.
