ABSTRACT:
An inker for a printing press in which an excess of ink is applied to the surface (45) of a resilient roller and the ink is metered by a metering member (10') to form a film of controlled thickness on the resilient roller surface. The metering member is a long strip including a polished metering surface and a polished support surface (26) which intersect to form a polished metering edge (25), the polished support surface (26) intersecting with a polished trailing surface (28a) to form a polished trailing edge (28b). The metering edge (25) and trailing edge (28b) are closely spaced such that the entire support surface is indented into the resilient roller surface for metering a film (130) of ink and for assuring that the ink will separate cleanly from the metering member at the trailing edge (28b). The leading or metering edge (25) is indented into the resilient roller surface (45) further than the trailing edge (28b) which results in the formation of a film (130), the thickness of which does not change substantially with a change in press speed.
