Abstract
A process and method which `locks in` three-dimensional texturing added to a paper web by virtue of an adhesive material which is printed onto the surface of the web is generally disclosed. The adhesive may be applied to the web either before, during, or after the web is molded to increase the surface texture. The adhesive may be applied at relatively low pressure so as to preserve surface texture without significant deformation of the web. The cured adhesive material inhibits the web from reassuming a two-dimensional state or may contribute additional texture by rising above the surface of the web. This process may not only increase the bulk of the web when dry and wet, but also increase the wet resiliency, the wet strength, and the tactile properties of the web.
