PURPOSE: To make it impossible to give a visually disadvantageous impression and to obstruct operation work in a printing machine by incorporating a filter easing in which a prefilter is provided in the printing unit of the printing machine. CONSTITUTION: In the prefilter apparatus for damping water of a printing machine having at least one printing unit 1, a filter casing 7 having a prefilter 6 provided therein is provided to be incorporated in the printing unit 1 of the printing machine. That is, since a known prefilter apparatus is arranged in the separate casing arranged outside the printing machine, a visually disadvantageous impression is imparted and the operation work in the printing machine is obstructed. By this constitution, the defect of this conventional technique can be excluded. |
