ABSTRACT:
A direct-to-press imaging system for use in lithographic printing wherein a master-image printing cylinder is used with separate application of ink and water onto its surface to enable repetitive conveyance of image-formatted ink films onto substrates for printing purposes. The imaging system includes a master-image printing cylinder adapted for receiving a hydrophilic coating layer on its surface and a device for laying down a uniform layer of hydrophilic material on the surface of this cylinder. An apparatus is also provided for applying oleophilic material in image-formatted patterns on top of the layer of hydrophilic material on the master-image printing cylinder to form a printing structure having separate hydrophilic and oleophilic areas of the format to be printed. Further, a mechanism is provided for removing the printing structure including both the hydrophilic and oleophilic materials from the surface of the master-image printing cylinder so that a new printing structure corresponding to a new image to be printed can be formed on the master-image printing cylinder.
