Ink printing abrasion tester, also known as ink decolorization tester or ink printing decolorization testing machine, is a specialized equipment used to test the abrasion resistance of printed matter ink layer, PS plate photosensitive layer, and product surface coating. This device evaluates ink adhesion and coating durability through tests such as dry grinding, wet grinding, and decolorization changes. It is widely used for analyzing the scratch resistance of printed materials, inspecting ink layer detachment, and controlling production process quality.
