Soft, absorbent paper webs and processes for making them. In the process, an aqueous dispersion of the papermaking fibers is formed into an embryonic web on a first foraminous member such as a Fourdinier wire. This embryonic web is associated with a second foraminous member known as a deflection member. The surface of the deflection member with which the embryonic web is associated has a macroscopic monoplanar, continuous, patterned network surface which defines within the deflection member a plurality of discrete, isolated deflection conduits. The papermaking fibers in the web are deflected into the deflection conduits and water is removed through the deflection conduits to form an intermediate web. Deflection begins no later than the time water removal through the deflection member begins. The intermediate web is dried and foreshortened as by creping. The paper web has a distinct continuous network region and a plurality of domes dispersed throughout the whole of the network region.

A strong, soft, absorbent paper web of papermaking fibers, said web comprising: (A) A macroscopically monoplanar, patterned, continuous network region having a relatively low basis weight and a relatively high density; and (B) A plurality of discrete domes having relatively high basis weights and relatively low densities, essentially all of said domes being dispersed throughout, encompassed by, and isolated one from another by said network region wherein the average density of said network region is from about 0.400 to about 0.800 gram per cubic centimeter, the average density of said domes is from about 0.040 to about 0.150 gram per cubic centimeter, and the ratio of the average basis weight of said network region to the average basis weight of said domes is less than about 1.0 and greater than about 0.8.
