Abstract
The disclosure describes an apparatus for treating fountain solution which comprises a recirculation assembly and a microporous filter assembly. The recirculation assembly is connected between the outlet and inlet of a fountain solution tray of a printing system. The recirculation assembly includes a fountain solution sump and a return line which extends from the outlet of the fountain solution tray to the sump. The microporous filter assembly is positioned in the sump or in the return line and includes a filter position across a fountain solution flow path. A pressure sensitive device is cooperatively arranged with the filter to bypass the filter in response to a predetermined pressure differential.
