Lorentzen & Wettre Introduces Stylus Roughness Tester Emveco

L&W Stylus Roughness Tester Emveco is a paper laboratory instrument that measures the micro-surface roughness of paperboard and linerboard.

April 22, 2013 - 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.

All measurement and analysis is done inside the instrument, no extra software or computer is needed. The testing procedure is fully automated. A photocell detects the presence of sample. The reference head is automatically lowered against the sample to rest against the paper sample. The reference head moves at a constant speed relative to the sample and the stylus follows the contours of the surface. After a defined measuring distance the reference head is lifted and moved back to the start position. The sample is then fed to next measuring position by the sample feeder. Each measurement takes less than 10 seconds.

“Finally there is a replacement of the popular EMVECO 210R. Stylus measurements has proven to be an excellent predictor of how well a flexo printed surface will print with minimum ink consumption with remaining print uniformity,” says Mr Thomas Fürst, Product Manager, Lorentzen & Wettre. The instrument is designed with attention to ergonomics and efficiency; easy to use colour-touch screen with intuitive menus and large easily accessible buttons, quick response and high resolution.

An integrated strip feeder facilitates extensive measurements, since each position can be measured at a fixed distance and continued until the strip ends. To speed up the strip measurement, the strip feeder can be set to measure more frequent at certain positions and less on other.
