emco IAS - Topography of Paper

All applications are based on the original algorithms of Dr. Praast. The image is obtained by the camera. The numerical results and the images are availible after seconds.

In addition to established products new evaluation methods for paper topography are developed in close collaboration with Dr. Hermann Praast and end users: greasiness/ calander mottling as well as marks of felt, wire and dandy roll.
