ABSTRACT:
A printing system incorporating a re-usable ink image transfer surface. A material which forms a thin hydrophobic layer is arranged by various techniques over a substantially hydrophilic transfer surface in a configuration which defines the desired latent image in terms of exposed, contiguous hydrophilic and hydrophobic areas. In some cases, a hydrophilic layer may be in direct contact with the hydrophobic layer. Depending upon the configuration of the layers, either an aqueous or oleo ink may be used to develop and print an image. If desired, the layer configuration may be replaced by a different configuration without substantial interruption to the printing process. No photo-induced chemical reaction or latent image developing steps are required at any time. The ink image transfer surface may be a planographic printing screen or a printing screen.
