An improved method for imprinting a paper web during a wet pressing event is disclosed which results in asymmetrical protrusions corresponding to the deflection conduits of a deflection member. In one embodiment, differential velocity transfer during a pressing event serves to improve the molding and imprinting of a web with a deflection member. Improved deflection members are also disclosed. Improved tissue webs produced are also disclosed having useful sets of physical and geometrical properties, such as a pattern densified network and a repeating pattern of protrusions having asymmetrical structures.
