Abstract:
A method of delivering dampening solution to a plate cylinder in an offset printing press system having an inking train of rollers which provide ink to the plate cylinder and having an independent dampening train of rollers separate from the inking train to exclusively provide dampening solution to the plate cylinder comprising the steps of:providing at least four rollers in the dampening train of rollers including a dampening solution transfer roller, a dampening form roller, a single mechanically driven drive roller and at least one rider roller;engaging the plate cylinder with the dampening form roller;surrounding the single mechanically driven drive roller with the dampening solution transfer roller, the dampening form roller and the at least one rider roller; andengaging the at least one rider roller at a location about a circumferential surface of the single mechanically driven drive roller at a supply side of the drive roller between the dampening solution transfer roller and the dampening form roller such that the single mechanically driven drive roller provides rotational movement of the at least one rider roller and the dampening form roller independent of the inking train of rollers.
