Printed packaging, labels, cartons, and coated materials must maintain their appearance and readability throughout production, transportation, storage, and consumer use. The ink rub tester<\/strong> provides a reliable method to evaluate whether printed inks, coatings, and surface finishes can withstand repeated friction without smearing, fading, transferring, or losing adhesion. By simulating real-world rubbing conditions, this testing equipment helps manufacturers verify print durability and improve product quality.<\/p>\n\n\n\n

The RT-01 Rub Tester from Cell Instruments is designed for professional abrasion resistance evaluation based on widely recognized methods, including ASTM D5264<\/strong>, TAPPI T830<\/strong>, \u0438 sutherland rub test<\/strong> principle. It supports dry rub, wet rub, heated rub, wet bleed, and smear evaluation for printed materials and coated substrates. With adjustable test speed, selectable loads, touchscreen operation, and customizable configurations, the instrument provides laboratories and quality control teams with an efficient solution for assessing print and surface performance.<\/p>\n\n\n\n

What Is an Ink Rub Tester?<\/h2>\n\n\n\n

\u0415\u0434\u0438\u043d ink rub tester<\/strong> is a laboratory instrument used to measure the resistance of printed ink, coatings, varnishes, and surface treatments against mechanical abrasion. The test evaluates how well printed surfaces maintain their visual quality when subjected to repeated rubbing forces.<\/p>\n\n\n\n

During daily use, printed products experience continuous friction. Examples include:<\/p>\n\n\n\n

    \n
  • Folding cartons rubbing against each other during transportation<\/li>\n\n\n\n
  • Labels contacting packaging equipment during manufacturing<\/li>\n\n\n\n
  • Flexible packaging surfaces rubbing during filling and handling<\/li>\n\n\n\n
  • Printed instructions or markings being touched repeatedly by users<\/li>\n<\/ul>\n\n\n\n

    Without sufficient rub resistance, printed information may become unclear, causing quality complaints, brand damage, or regulatory concerns.<\/p>\n\n\n\n

    The ink rub tester recreates these conditions by moving a weighted receptor across a test specimen with controlled pressure and motion. After a defined number of cycles, operators evaluate ink transfer, color loss, smearing, or coating damage.<\/p>\n\n\n\n

    Why Rub Resistance Testing Is Important<\/h2>\n\n\n\n

    Print durability is a key quality indicator for packaging and printed products. A visually attractive package must also maintain its appearance throughout its expected lifecycle.<\/p>\n\n\n\n
