Abstract (en)
A method is provided for minimizing the rewetting of a sheet after wet pressing of the same with a water receiver, the method comprising: forming before or during the pressing together of the sheet and the water receiver, a surfactant laden or foam-filled region at an interface between the sheet and the water receiver; and separating the water receiver from the sheet after the pressing of the two together. The method allows for the formation of sheets having higher solids after wet pressing. <IMAGE>
