ABSTRACT:
To permit efficient re-transport of ink-water emulsion from a plate cylinder to the ink trough, and permit formation of ink accumulation and ink pools, particularly when mixed with wetting water, a cage-like holder is provided in which a plurality of roller elements, for example balls or elongated pins or cylindrical rollers, all with ink-accepting surfaces, are in surface-frictional engagement with a pair of rollers which project from the cage-like container. The rollers projecting from the container are in contact, respectively, with the ink duct roller receiving ink from an ink trough and another roller of the ink distribution train of the ink distribution system of the printing machine, preferably with the transfer roller receiving ink from the duct roller, to provide a bypass and re-transport path for water-ink emulsion, particularly when printing on paper or of a subject matter which covers less than the width of the plate cylinder so that ink is not removed by the printing operation throughout the width of the rollers.
