| 4451145 | Apparatus and process for making lithographic printing plate with reinforced image Lithographic printing plates are made by exposing to actinic light a lithographic plate having a water soluble light sensitive layer thereon and a coating of a solvent soluble, UV curable material thereover to form an image in the light sensitive layer an... | 05/29/1984 |
| 4414315 | Process for making lithographic printing plate Process for making a lithographic printing plate having an oleophilic amplified image prepared by (a) providing a silicated aluminum substrate with a hydrophilic, anionic, negatively charged surface and a layer on said surface of a light sensitive, cation... | 11/08/1983 |
| 4396284 | Apparatus for making lithographic printing plates Lithographic printing plates are made by exposing to actinic light a lithographic plate having a water soluble light sensitive layer thereon to form an image in said layer. A solvent soluble, UV curable material is adhered to the image in said layer. The ... | 08/02/1983 |
| 4391897 | Diazo lithographic printing plate developing process Process for removing unexposed diazo from a silicated aluminum lithographic printing plate having a hydrophilic, anionic, negatively charged surface and a layer of a light sensitive, cationic diazo material which has been selectively exposed to actinic li... | 07/05/1983 |
