Abstract:
1. A method for use in fabricating an embosser drum, comprising: using an embossing master that includes a surface with a pattern of nanostructures to create an embossing plate that includes a pair of opposing end surfaces and a pair of opposing major surfaces, wherein the embossing plate includes the pattern of nanostructures on a first of the opposing major surfaces; welding the opposing end surfaces of the embossing plate together at a single seam to form a cylinder, wherein an interior surface of the cylinder comprises the first major opposing surface of the embossing plate; producing, using the interior surface of the cylinder, an embosser drum, wherein an outer embossing surface of the embosser drum comprises the pattern of nanostructures, wherein the producing includes applying a metallic layer on the interior surface of the cylinder to produce the embosser drum, and; separating the cylinder from the embosser drum, wherein the separating includes:
