The novel tissue products of the present invention are generally produced by calendering a tissue basesheet using at least one patterned roll. In one embodiment the patterned roll replaces the flat steel roll commonly used in calendering. The elements on the patterned roll provide a means of providing a nip having variable loading that yields a web having a smooth surface without subjecting the web to excessive compression forces and preventing excessive caliper loss. Thus, webs converted according to the present invention have comparable or better surface smoothness compared to webs converted using conventional calendering means and also retain a greater percentage of their caliper and bulk.
