A microreplicated article is disclosed. The article includes an opaque web having first and second opposed surfaces. The first surface includes a first microreplicated structure having a plurality of first features. The second surface includes a second microreplicated structure having a plurality of second features. The first microreplicated structure and the second microreplicated structure retain registration within 100 micrometers.

Microreplicated article

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.

Apparatus and method for producing two-sided patterned web in registration

A microreplicated article is disclosed. The article includes a web including first and second opposed surfaces. The first surface includes a first microreplicated structure having a plurality of first features. The second surface includes a second microreplicated structure having a plurality of second features. Corresponding opposed features cooperate to form a lens features.
