An ink fountain assembly for use in duplicating machines, such as rotary lithographic machines. The assembly comprises a fountain trough defined by an elongated blade and an ink fountain roller defining a gap therebetween. A proximal edge of the blade is rigidly retained and a distal edge of said blade, adjacent said roller, engaging a portion of the frame and being initially flexed and prestressed toward said roller to define the gap. The gap may be varied to control ink flow therethrough.
