Abstract
An apparatus for casting a patterned surface on both sides of an opaque web. The apparatus includes a first patterned roll, a second pattered roll, and a means for rotating the first and second patterned rolls such that their patterns are transferred to opposite sides of the opaque web while it is in continuous motion. During this process, their patterns are maintained in continuous registration to within at least 100 micrometers.
