Abstract: A system and a method for making a web having a complex topography. A substrate having coatable material is contacted by a face-side roller having grooves set into the major surface thereof, the coatable material is then split between the face side roller and the substrate, resulting in a textured surface having a first area associated with the splitting from the major surface, and a second area resulting from splitting associated with areas of the face-side roller having grooves. Raised ridge features produced from the splitting step interconnect portions within the first area, and portions within the second area, and in between the first and second area.

Abstract: The present disclosure provides multilayer stacks that can be used as decorative microsphere articles. The decorative microsphere articles can be a durable and aesthetically pleasing substitute for anodized aluminum and other matte metallic surfaces.
