Bekk Smoothness Tester

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. 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.

Parker Print-Surf (Dual Head)

Developed from Dr. John Parker's original method, the Parker Print-Surf is a microprocessor-controlled instrument, which performs high speed, precision measurements of paper surface roughness under conditions that simulate those encountered during the printing process. The specimen is clamped between a precision engineered measuring head and a specially designed backing assembly. The resistance to airflow is measured and converted to a mean roughness value in micrometers. In its latest form the instrument offers extended ranges of clamp pressure and measurement capability, together with a dual-head option for increased testing efficiency. This versatile instrument provides the information you need to avoid time-consuming, costly printing problems.

Parker Print-Surf (Single Head)

Developed from Dr. John Parker's original method, the Parker Print-Surf (PPS) is designed to accurately measure the surface roughness of sheet materials under conditions similar to those experienced during the printing process. The sample is clamped between a precision engineered measuring head and a specifically designed backing assembly. It provides the information you need to avoid time-consuming, costly printing problems.
