Summary:A solvent-soluble, radiation-polymerizable, oleophilic resin coating non-ionically adhered on a hydrophilic substrate can be imagewise exposed to polymerizing radiation and then directly processed by the application of disruptive mechanical forces such as compression or tension to remove the unimaged areas as undissolved particles, using pressurized water and brushing pre-press, or the tack of the ink on-press.
