Overview
The Printing Surface Strength Tester by QGI is a precision laboratory instrument designed to evaluate the surface strength and printability of paper and paperboard. This device measures the resistance of paper surfaces to picking or linting during printing, making it an essential tool for paper manufacturers, printing houses, packaging industries, and ink laboratories.
By simulating the mechanical forces experienced during the printing process, the tester helps determine whether the paper surface can withstand ink transfer without fiber lifting or coating damage. Accurate measurement of surface strength ensures consistent printing quality, improved ink adhesion, and optimized paper production control.
The QGI Printing Surface Strength Tester is suitable for testing both coated paper and uncoated paper, and it provides reliable data for evaluating the compatibility between paper and printing inks. It is widely used in quality control laboratories and research facilities within the paper and packaging industries.
