An apparatus and process for removing water from a cellulosic web. The papermaking apparatus comprises imprinting member having an absolute void volume that enables a hydraulic connection to be formed between a cellulosic web and a capillary dewatering member when compressed in a nip. The absolute void volume is predetermined based on an estimate of the volume of water expressed from the cellulosic web.
