<p>A presensitized plate with compound support includes an aluminum substrate (1) having a front side and a back side, and a sensitization imaging layer set up on the front side of the aluminum substrate, wherein the back side of the substrate (1) is covered with a membrane (2) of polymer material forming the structure of compound support. A manufacturing process of presensitized plate with compound support according to the invention comprises deoiling and cleaning the aluminum substrate (1), conducting electrochemical corrosion and roughening for the surface of the substrate (1), generating oxidation layer through the oxidization of anode, conducting sealing or a hydrophilic treatment for the oxidation layer, coating sensitization liquid onto this oxidation layer, finally drying and cutting the plates into finished products, wherein back side of the substrate (1) may be covered with a membrane (2) of polymer material after deoiling and cleaning the substrate (1).</p> |
