Lorentzen & Wettre, a member of the ABB Group, announce L&W Stylus Roughness Tester Emveco – a paper laboratory instrument that measures the micro-surface roughness of paperboard and linerboard.
The evaluated property is called microdeviation, which is a measure of the topography of the paper or board surface, and a characteristic that correlates well to how a paper or board will print. This new product is a replacement of the well-known EMVECO Stylus Roughness Profiler System 210-R, used in the industry for many years.
