Bendtsen Type-03 Products Paper Testing Instruments Surface Roughness Smoothness Tester Bendtsen Type-03
|
|  The instrument is designed to precisely measure the surface roughness of writing / printing paper coated paper and other similar grade of paper, under conditions as equal to those facing during the printing press nip and at the moment of printing.
Surface Roughness
Surface roughness is very much interest for good printing results. The layer of ink must be thicker than the roughness to give a good and glossy print. The amount of ink used is not only a cost but also influence the drying time and thus the risk is set off. With more ink there is also bigger risk for print -through problems. Also in certain other operations the roughness plays an important role. When lamming paper with metal foil or with plastic film, the overall results depends very much on the surface roughness of the base paper used. Typical grades for roughness measurements range from newsprint to linerbaord.
