Abstract (en)

[origin: DE19859246A1] The printing process involves altering the flow ratios inside the casing (24) of the paper output end (22) by supplying outside air into the casing or sucking air out of the casing, breaking the air flow along the non-driving free length of the paper feed at one or more points between the free ends of the non-driving free length and the printing press. The sheet offset printing press (2) has a dusting device (50) in the casing to dust the printed paper with powder, and air input and sucking-out devices (58, 56).
