An ink fountain assembly for use in duplicating machines, such as rotary offset lithographic machines. A fountain trough is defined by an elongated blade extending along one side of the trough and an ink fountain roller extending along the other side of the trough defining a gap therebetween. A plurality of independently adjustable thumb screws are provided for varying the gap and the ink flow therethrough. A plurality of caps are positionable over the thumb screws in any angular position relative thereto. The caps have indicators to facilitate calibrating the positions of adjustment of the thumb screws.
