Rub Proofness (Scuff) Tester
Tests print durability — ensures lasting quality — TI/ST/PT-32
The Rub/Scuff Tester measures resistance to rubbing of printed paper or board. It can also be used to measure colour transfer from printed or coated material during rubbing. It evaluates the extent of colour transfer from printed or coated materials due to rubbing — a condition which frequently occurs during the handling and shipment of packaged goods. The Rub Proofness Tester consists of two discs. Pressure between the discs being determined by a dead load applied to the upper disc. Both rotate at the same angular speed. The relative velocity between all points on each disc is uniform and passes uniformly through all directions in the plane of contact to obtain uniform rubbing.
