The Automatic Bekk Smoothness Tester is a microprocessor-controlled instrument for the determination of smoothness of paper and board according to the Bekk Method.

This air leak smoothness test 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.
