Ink Rub Tester

Testmaterial

This tester evaluates inks and coatings on container board, corrugated board, paper, cartons, plastic films, labels, and printed packaging materials. Both printed and unprinted samples can be tested.

Testprocess

The RT-01 Ink Rub Tester uses a motor-driven arm to move a weighted specimen over the sample surface in a 57 mm arc, simulating rubbing or scuffing. Tests include dry rub, wet rub, wet bleed, wet smear, heated rub, and functional rub. Test speed (20-120 cpm) and pressure (2 lb or 4 lb weights) are adjustable to replicate various conditions.

Tolkning av testresultat

Test results reveal ink resistance to wear, surface strength, smearing, bleeding, heat resistance, and adhesion. Strong performance indicates durable inks and substrates, while poor results suggest formulation or process improvements are needed.
