An ink fountain apparatus for a rotary printing press includes a rotatably supported ink fountain roller, an ink fountain, at least one intermediate ink dam, a press unit, and an adjustment bolt. The ink fountain is comprised of an ink fountain blade and a pair of ink dams. The intermediate ink dam stands upright between the ink dams from the ink fountain blade. The intermediate ink dam includes a press plate in contact opposite to an outer surface of the ink fountain roller and the ink fountain blade, an adjustment plate in contact opposite to the press plate, and an operation plate in contact opposite to the adjustment plate. The press unit includes a compression coil spring, operation rod, press shaft portion, and engaging surface that press the press plate through the operation plate and adjustment plate toward the outer surface of the ink fountain roller and toward the ink fountain blade. The adjustment bolt adjusts a tight contact state of the press plate with respect to at least one of the outer surface of the ink fountain roller and the ink fountain blade.
