Abstract
A filtration system, mechanism and method is proved that continuously filters waste fluid from variable data ink-based printing system cleaning subsystems. Waste fluid from a cleaning subsystem is forced through a bank of progressively finer filter media. Initial coarse filters remove large components of the ink and/or skin that would rapidly clog the later finer filters required to remove small components of the ink and/or skin. The filtered fluid is recycled for printing surface cleaning and filtration. To avoid clogging, the filter media are cleaned by reversing the flow of fluid through the filters. This back-flushing operation is accomplished with a relatively small volume of fluid that is routed as concentrated waste fluid to a waste container for disposal. To avoid disruption to the printing process, two or more filter banks are preferably used. While one filter bank is filtering the waste fluid any other bank(s) may be back-flushed.
