Ink Rub Tester (Sutherland Type)
Abrasion resistance is a desirable and sometimes critical property of printed materials. Abrasion damage can occur during shipment, storage, handling and end-use. The result is a significant decrease in product appearance and legibility of product information. The amount of abrasion damage to a printed surface is dependent shipping conditions, possible temperature and humidity, time and many other variables.
In this machine, 2 samples of the same substrate (or different substrates) are rubbed against each other in the same plane (in linear direction), under a fixed pressure (user-variable) and at a fixed speed (user-variable).
The number of rubs are recorded using a non-contact type digital counter.
