1. A process consisting of:
providing a paper substrate;
disposing a water soluble precoat composition onto a portion of the paper substrate to provide a treated paper;
applying an image onto the water soluble precoat composition using a toner or an aqueous ink to provide an imaged paper;
wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate; and
wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate.
