Gardco’s Digital Ink Rub Tester is designed to measure scuffing or rubbing resistance. Several tests can be performed including dry rub (the amount of transfer ink from one dry surface to another), wet rub (the amount of transfer of ink from wetted surface to another), wet bleed or transfer (ink transfer to a water-saturated blotter), wet smear (similar to wet bleed with the addition of rub cycles), functional rub/wet rub (smear or transfer tests using a liquid other than water and hot abrasion)...
