Working principle and maintenance method of ink decoloring tester

Principle of ink bleaching tester: It is used to test the adhesion of the ink to judge the quality of the ink. The machine can be used for dry grinding test, wet grinding test, decolorization change test, paper blur test and special friction test. Ink abrasion test is a test method designed to evaluate the abrasion resistance or abrasion resistance of ink on paper or cardboard. It is also called ink decoloration tester, ink printing decoloration tester, ink decoloration tester, ink friction tester, It belongs to the most typical type of printing inspection equipment.
