Paper Bekk Smoothness Tester

The Paper Bekk Smoothness Testerr is microprocessor-controlled instrument for measuring the smoothness of paper and board according to the Bekk method.

This Paper Bekk Smoothness Tester is useful for very smooth surfaces, for example, coated label papers, coated free sheet, or other very smooth papers. Test results generate with the Bekk tester have shown excellent correlation with print smoothness evaluations using offset ink. Likewise, Bekk results have shown good agreement with subjective evaluations of low angle illuminated surface photomicrographs. Surface integrity is particularly important for printing papers. The surface fibers must be sufficiently bonded to those beneath the surface and the coating bond to the fiber matrix must be sound.
