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). According to a second embodiment, the installation (02) further comprises a decantation unit (13a) for separating the waste solution coming from the flocculation tank (12) by decantation into precipitate and decanted supernatant, which decanted supernatant is fed to the processing tank (14), and a centrifugation unit (13b) for further separating the precipitate produced by the decantation unit (13a) by centrifugation into further precipitate and centrifuged supernatant, which centrifuged supernatant is fed to the processing tank (14). There are also described corresponding processes for recycling wiping solution.
