The system comprises a wiping tank (1), a wiping roller (2) rotatably supported in the wiping tank and having a circumferential surface and cleaning means for cleaning the surface of the wiping roller, said cleaning means comprising at least a first spray unit (4) for spraying clean wiping solution against the surface of the wiping roller and a drying blade (12) placed downstream of said first spray unit with respect to a direction of rotation of said wiping roller for removing wiping solution residues from the surface of the wiping roller. The cleaning means further comprise a cleaning assembly including at least one supporting plate (5; 25) with a series of holes (5', 30, 31, 32, 33) and holding means (7, 8, 10, 11) for holding the supporting plate, said supporting plate being conformed to extend parallel to a part of the circumferential surface of the wiping roller without touching said wiping roller. The cleaning assembly further comprising at least a cleaning sheet (6; 26, 26a, 26b) made of porous material placed on said supporting plate and in contact with the surface of said wiping roller for removing ink therefrom. The first spray unit (4) is disposed before an upstream end of the cleaning assembly with the respect to the direction of rotation of the wiping roller (2) in such a way as to spray clean wiping solution directly between the surface of the wiping roller (2) and the upstream end of the cleaning assembly.
