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.
The IGT Rub tester is intended for objective and reproducible tests under standard, pre-programmed or pre-set conditions. With this device, one can simulate both normal and excessive stresses on printed and unprinted products (two specimen – printed & unprinted sample to be used for test). Generally, the printed sample is rubbed against a foreign material with specific abrasion properties in case of abrasion, or against the back or the same side of the same type of substrate in case of rub
The IGT Rub Testers is used by :
Printing Ink Industry, security printers, Packaging printers, Pigment, Resin and varnish industry, Chemical Industry, Raw materials suppliers, Training centers, R&D institutes, Universities.
