Apparatus and a method for printing and drying layers of ink applied to the surface of a continuous substrate in a multi-stand offset press comprising a plurality of stands, each having a printing portion for the application of a layer of ink to the substrate as it passes through the stand, and a drying assembly mounted after and adjacent each printing stand portion and adjacent the substrate for drying the substrate and layer of ink thereon after passage therefrom. The drying assembly comprises an emitter-cooler that radiates energy toward the ink-layered substrate and gas duct that directs air toward the ink-layered substrate to dry the substrate and layer of ink thereon contributing to further drying thereof and evaporation of water vapor and solvents arising therefrom.

[ I claim:] [1.] Apparatus for printing and drying a continuous substrate fed along a feed path through a plurality of stands to the end of the feed path, the apparatus comprising:(A) a printing portion in a plurality of said stands, each printing portion capable of applying an ink layer to a surface of said substrate,(B) a drying assembly mounted after and adjacent the printing portions of a plurality of said stands, each drying assembly comprising(1) emitter means for radiating energy toward said substrate surface and layer of ink thereon, and(2) a gas conduit positioned adjacent the emitter means for directing a flow of cool gas onto said substrate surface and layer of ink thereon, the cool gas being at a temperature lower than the operating temperature of the adjacent printing portion, energy from the emitter and flow of cool gas from the gas conduit serving to dry the substrate surface and layer of ink thereon passing adjacent each said drying assembly prior to the end of the feed path.
