International ClassB41F 023/04AbstractApparatus and a method for printing and drying layers of ink applied to the surfaces of sheets fed through a press and discharged from the press delivery end, without the use of powders, one upon another onto a stacker without off-set or blocking, comprising a plurality of stands, each having a printing portion for the application of a layer of ink to the sheets, and a drying assembly mounted after and adjacent thereto for drying each sheet and the layer of ink thereon within the press stand prior to passage therefrom. The drying assembly comprises an emitter-cooler that radiates energy toward each sheet to dry the sheet and layer of ink thereon and a gas conduit that directs gas from a nozzle toward each sheet and the layer of ink thereon contributing to further drying thereof and evaporation of the water vapor and solvents arising therefrom. | |
