Abstract: There is described an installation (01; 02) for recycling wiping solution of one or more intaglio printing presses (10) comprising a flocculation tank (12) for inducing flocculation of ink constituents contained in waste solution coming from the one or more intaglio printing presses (10), a processing tank (14) for pre-treating the waste solution for subsequent filtering, and a filtering unit (15), preferably a filter press unit, for filtering the waste solution coming from the processing tank (14) and producing recycled solution at an output of the filtering unit (15), which recycled solution is recycled to produce fresh wiping solution for use by the one or more intaglio printing presses (10). According to one embodiment, the installation (01) further comprises a centrifugation unit (13) for separating the waste solution coming from the flocculation tank (12) by centrifugation into precipitate and centrifuged supernatant, which centrifuged supernatant is fed to the processing tank (14).

Abstract: The process is composed of the following steps: (a) production of the fresh wiping solution, (b) introduction of the fresh wiping solution into one or more wiping tanks, where it is contaminated by the inks. In addition, it comprises the following steps: (c) treatment of the used solution exiting from the wiping tank or tanks with a chemical agent, producing a solution and sedimented ink, (d) separation by settling of the solution obtained in step (c), producing a clean solution and a concentrated solution with sedimented ink, (e) filtration of the concentrated solution, producing a clean solution and solid waste, and (f) use of the clean solution obtained in steps (d) and (e) as fresh wiping solution.
