Device for controlling the deposition of coloured substance(s) and of wetting solution for an offset printing system and method for implementing the device

Abstract

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 coloured 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 coloured 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 coloured substance, each of these hydrophilic and lipophilic surfaces being separated from its direct neighbours by at least one hydrophobic and lipophobic peripheral surface.
