Abstract: To separate a flexographic ink fountain into axial zones (10a, 10b . . . ) to permit use of inks of different characteristics, for example different colors along axial zones of an anilox roller (10), a separator element (2) has an insert strip element (3) extending over a portion of the circumference of the anilox roller, and resiliently engaged thereagainst, for example by compressed silicone rubber (5). Adjacent the end of the strip element (5) are two felt pads (21, 31) which are supplied from a source of separating fluids, such as water, alcohol-water solution or the like, to apply a ring-shaped film of the separating liquid on the anilox roller which film will continue beneath the separating strip (3), the separating strip being engaged against the roller with sufficient pressure to permit the strip to ride on the liquid film, similar to planing of autombile tires on a wet road surface.
