International ClassB41F 035/00AbstractApparatus 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.Other References
