Japanese Patent JP3350098
Kind Code:
B2
Abstract:
A direct-to-press imaging system for use in lithographic printing wherein a master-image printing cylinder (10) 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 (10) adapted for receiving a hydrophilic coating layer (26) on its surface and a device (30,32) for laying down a uniform layer of hydrophilic material (22) on the surface of this cylinder. An apparatus (35,80,88) is also provided for applying oleophilic materials (34) in image-formatted patterns on top of the layer (26) of hydrophilic material on the master-image printing cylinder (10) to form a printing structure having separate hydrophilic and oleophilic areas of the format to be printed. Further, a mechanism (44,46) is provided for removing the printing structure including both the hydrophilic (22) and oleophilic materials (34) from the surface of the master-image printing cylinder (10) so that a new printing structure corresponding to a new image to be printed can be formed on the master-image printing cylinder (10).
