DEVICE FOR CONTROLLING THE DEPOSITION OF COLOURED SUBSTANCE(S) AND OF WETTING SOLUTION FOR AN OFFSET PRINTING SYSTEM AND METHOD FOR IMPLEMENTING THE DEVICE

摘要

The present invention relates to a substance(s) deposition control device for an offset printing system, characterized in that it comprises:—at least one offset plate intended to receive a wetting liquid and a colored substance in succession,—at least one controlled-deposition means for each offset plate, the deposition means comprising at least one deposition head spraying at least one wetting solution and at least one deposition head spraying a defined colored substance,—at least one means for cleaning the offset plate, and in that the covering of the offset plate or plates comprises a mesh structure defined by a plurality of hydrophilic and lipophilic individual surfaces capable of receiving a controlled deposition of wetting liquid and/or colored substance, each of these hydrophilic and lipophilic surfaces being separated from its direct neighbors by at least one hydrophobic and lipophobic peripheral surface.
