Application
Ink rub testers are designed to evaluate the scuffing or rubbing resistance of an ink film or fiber surface on container board and corrugated board. A variety of tests may be made, including: dry rub; wet rub; heated rub; wet bleed or transfer; wet smear; and functional rub.
Significance
This method evaluates resistance of inks to either dry or wet rubbing or scuffing. It can also be used to evaluate dry or wet surface strength of coated container board. unprinted container board, and other similar surfaces as well as the smearing or bleeding of inks. A heated platen can also be used to evaluated heat resistance of inks and varnishes. Some use this test to differentiate between strong and weak ink films and their adhesion to container board.
Test Description
RT-01 is a motor-driven device for moving a weighted test specimen over the printed or unprinted sample through an arc of 57mm for a preset number of strokes.
Technical Features
PLC controlled unit (industrial level stable) and HMI touch screen operated.
It can be used for tests of dry rub, wet rub, wet bleed or transfer, wet smear and functional rub.
Other features include
Test speed random setting
Double Test Station stations arc movement structure
Test Samples
Inks, flastic film, fackaging, faper, labels, coatings, cartons, printed materials
