Abstract
A textured mask comprising a film. The film can have a first substantially continuously flat surface lying in a first plane and a second surface opposite the first surface lying in a second plane substantially parallel to the first plane. The second surface is interrupted by a plurality of cavities, each of the cavities having a first depth defined by a third surface lying in a third plane substantially parallel to the first and second planes. The depth of the cavities can be at a distance of from about 0.1 mm to about 5 mm from the second plane. The textured mask is at least partially coated with an opaque masking agent. The textured mask can make a correspondingly structured three-dimensional papermaking belt, which can make correspondingly structured three-dimensional fibrous structure.
