The present invention relates to a substance(s) deposition control device for an offset printing system comprising at least one offset plate intended to receive at least one substance so as to transfer the substance or substances onto a substrate, at least one means for the controlled deposition of at least one substance, the deposition means comprising at least one head unit spraying at least one wetting solution and at least one head unit spraying at least one colored substance, at least one means for cleaning the offset plate. The covering of the offset plate comprises a mesh structure defined by a plurality of hydrophilic and lipophilic individual surfaces capable of receiving a controlled deposition of substance(s), each of these hydrophilic and lipophilic individual surfaces being separated from its direct neighbors by at least one hydrophobic and lipophobic peripheral surface. The invention also relates to a printing system incorporating the device and to a printing process implementing the device.

Substance(s) deposition control device for offset printing system and method for implementing the device

The present invention relates to a substance(s) deposition control device for an offset printing system, characterized in that it comprises:&#x2014;at least one offset plate intended to receive a wetting liquid and a colored substance in succession,&#x2014;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,&#x2014;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.
