Abstract

A testing device for checking the quality of a paint or lacquer layer includes at least one friction element moving device. To prevent an impression on a test region, the friction element moving device is configured to (i) initially move at least one friction element in frictional contact along a defined path, e.g., a circular path, over a test region of a paint or lacquer layer, and (ii) subsequently eliminate the frictional contact between the friction element and the test region during the movement of the friction element.
