Abstract
The present application provides a method of manufacturing a patterned tissue product comprising a textured background surface, and a design element wherein the design element is formed by removing a portion of the textured background. The method comprises the steps of (a) providing a tissue web having a textured top surface lying in a surface plane and a bottom surface lying in a bottom plane wherein there is a z-directional height difference between the surface plane and the bottom plane; (b) conveying the web through a first nip created by a first receiving roll and a pattern roll having a plurality of protuberances forming a design pattern; (c) conforming a portion of the web to the protuberances; and (d) conveying the web into a second nip formed between the pattern roll and a second receiving roll to form a patterned tissue product having a design element corresponding to the plurality of protuberances, the design element lying in a design element plane that is between the surface plane and the bottom plane. The textured surface provides the tissue with an overall background pattern that is typically visually distinct from the design element imparted thereon. The method may f…
