The present invention relates to a method for producing a print medium with enhanced whiteness and print quality. The method comprises applying a surface treatment composition of a general formula Cx(A)y(OH)z(SiO2)kSm where C is a cation, A is an anion, and S is a moiety that provides a surface charge selected from surface modifiers, stabilizing agents, and combinations thereof. A facet of the enhanced print quality includes, for example, improved inkjet printing characteristics selected from print density of a printed ink on the print medium, line growth of a printed ink on the print medium, bleed of a printed ink on the print medium, edge roughness of a printed ink on the print medium, mottle of a printed ink on the print medium, wicking of a printed ink on the print medium, show though of a printed ink through the print medium, and any combination of the foregoing.
