Abstract
A standard offset printing press has the delivery end thereof modified with an air nozzle that is disposed above an underlying sheet travel path and which is designed to direct a continuous stream of pressurized air against the paper's top surface as it emerges from the printing press and is directed into a stacking area about the delivery end. The presence of the downwardly directed air tends to flatten the respective sheets and to prohibit curling. In addition, the printing press of the present invention is provided with a system for dispensing powder onto respective printed sheets such that once stacked the powder tends to separate the respective sheets.
