Abstract
The present invention relates to a method and apparatus for optimizing the characteristics of wetting water in offset and roto-offset printing machines, by a system for separating and trapping inks, foam and printing residues, (such as paper, solvents and the like) coming from the return water to the printing elements, to be then conveyed, by gravity falling or through a reconveying station, to an existing recirculating unit.
Claims12
An apparatus for improving characteristics of wetting water in offset printing machines, characterized in that said apparatus comprises coarse pre-filtering means, separating means defining one or more separating basins, ink recovering means arranged at a top of one or more of said separating basins, and empting valves.
A method for improving the characteristics of wetting water in offset printing machines, characterized in that said method comprises the steps of separating and trapping printing inks, foam and residues such as paper, solvents and so on, coming from return water returning from said printing elements, to be reconveyed by gravity falling or through a reconveying stations to a recirculating unit.
