Abstract

An ink dispensing system for a printing press having an ink trough of a fountain roller and comprising a plurality of radially oriented ink spreader assemblies arranged closely side-by-side to form a substantially continuous metering edge for zonal metering of a film of ink on the fountain roller as it rotates. Each printer assembly includes a bearing member and a dispensing member, the bearing member having a tip of narrow dimension and the dispensing member having a film-forming edge. Each bearing member is biased so that its tip rides in contact with the surface of the roller to establish a positional reference for adjustment of the dispensing member. An adjusting screw mounted on the bearing member and engaging the dispensing member is adapted to retract the dispensing member a small distance rearwardly of the tip of the bearing member to thereby determine the zonal thickness of the ink film formed on the surface of the roller by the dispensing member.
