Abstract
A process is disclosed for topically applying additive compositions to planar substrates, such as tissue webs. In one embodiment, the process is designed to apply relatively high viscous compositions to base sheets at high speeds in a manner that prevents the additive composition from penetrating into the sheet. The additive composition having the relatively high viscosity can be applied to the base sheet in one embodiment using an offset gravure printing process. The applicator roll includes a pattern of raised elements. The raised elements define a surface having at least one dimension that is less than 500 microns. The raised elements are also spaced closely together in order to prevent fiber buildup on the roll during relatively fast processing speeds.
