Ink Rub Test of Containerboard and Corrugated Board, Test Method
Overview of TAPPI T830 Sutherland Ink Rub:
TAPPI T830 Test Method evaluates the scuff resistance of ink and print on containerboard and corrugated material. Depending on the intended application, the material can be evaluated in multiple variations such as dry, wet, wet bleed, or transfer methods. This test involves rubbing a weighted stylus over a printed ink film surface several times, and then visually examining the tested area for any ink smudging or transfer. The results of this test are used to determine the print quality and durability of the ink on the substrate. A higher rub resistance indicates that the ink has better adhesion and is less likely to smudge or transfer during handling or use. Purple Diamond Testing offers TAPPI T830 Ink Rub Test of Containerboard and Corrugated Board as part of our packaging compliance and validation services.
Rationale of TAPPI T830 Sutherland Ink Rub:
TAPPI T830 Sutherland Ink Rub is a standard test method used to measure the ink rub resistance of printed or coated materials. It involves rubbing a wet or dry sample surface with a specified pressure and number of strokes under controlled conditions and assessing the degree of ink transfer or removal using a rating scale. The test helps to evaluate the durability and quality of printing inks, coatings, and substrates and to compare their performance against industry standards or customer specifications. This test method is ideal when verifying the durability of ink printing that needs to remain legible throughout the distribution cycle. This is achieved by rubbing a weighted receptor block against the printed substrate for a set number of cycles and inspecting for scuffing or ink transfer. Common examples include comparisons between ink or substrate options and print on multiple types of coated paper.
