Abstract: There is described a transfer member or blanket for use in aqueous ink jet printer. The transfer member includes a non-woven polymer fiber matrix and a polymer dispersed throughout the non-woven polymer fiber matrix. The polymer fiber matrix has a first surface energy and the polymer has a second surface energy. The difference between the first surface energy and the second surface energy is from about 30 mJ/m2 to about 5 mJ/m2.

Abstract: Provided is a method of patterning a substrate. The method includes depositing, in a first predetermined pattern, hydrophobic material on a first surface of a hydrophilic substrate. The method includes permeating the hydrophobic material through a thickness of the substrate. The method includes exposing the hydrophobic material to UV-light and sufficiently solidifying the permeated hydrophobic material. The sufficiently solidified hydrophobic material forms a liquid-impervious barrier that separates the substrate into at least one discrete region.
