Multifunction device for post-processing of a printing substrate web printed by an electrographic printing device

An electrographic printing device, comprising:

• a printing station printing images on a printing substrate web;
• after an output of the printing station a multifunction device receiving the printing substrate web;
• and
• said multifunction device comprising in succession
• a buffering device for the printing substrate web,
• at an exit of the buffering device a smoothing device having a first smoothing roller in direct contact with a first surface of the printing substrate web and a second smoothing roller in direct contact with a second surface opposite the first surface of the printing substrate web,
• at an exit of the smoothing device a directly following moistening device applying a moistening agent for the printing substrate web,
• at an exit of the moistening device a cooling device for the printing substrate web,
• a discharge device for the printing substrate web after the cooling device, and
• a lubrication device applying a lubricant in addition to the moistening agent for the printing substrate web before the discharge device.

A method for post-processing of a printing substrate web printed by a printing station of an electrographic printing device wherein in a transport direction of the printing substrate web after leaving the printing station in succession performing the steps of:

• buffering the printing substrate web with a buffering device;
• smoothing the printing substrate web in a smoothing device having a first smoothing roller in direct contact with a first surface and a second smoothing roller in direct contact with a second surface opposite to the first surface of the printing substrate web after the buffering device;
• moistening the printing substrate web with a moistening device applying a moistening agent directly following after the smoothing device;
• cooling the printing substrate web with a cooling device after the moistening device;
• discharging the printing substrate web with a discharge device after the cooling device;
• and
• lubricating the printing substrate web with a lubrication device applying a lubricant in addition to said moistening agent before the discharge device.

A multifunction device for post-processing of a printing substrate web printed by a printing station of an electrophotographic printing device, comprising after the printing station:

• a buffering device for the printing substrate web,
• a smoothing device having a first smoothing roller in direct contact with a first surface of the printing substrate web and a second smoothing roller in direct contact with a second surface opposite the first surface of the printing substrate web,
• a moistening device applying a moistening agent for the printing substrate web directly following the smoothing device,
• a cooling device for the printing substrate web,
• a lubrication device applying a lubricant in addition to said moistening agent for the printing substrate web,
• a discharge device for the printing substrate web, and
• the buffering device, the smoothing device, the moistening device, the cooling device, and the lubrication device each being separately deactivatable without being removed from the multifunction device and when deactivated do not influence a function of the remaining ones of the buffering, smoothing, moistening, cooling, and lubrication devices.

• buffering the printing substrate web with a buffering device;
• smoothing the printing substrate web with a smoothing device having a first smoothing roller in direct contact with a first surface and a second smoothing roller in direct contact with a second surface opposite the first surface of the printing substrate web;
• moistening the printing substrate web with a moistening device applying a moistening agent directly following the smoothing device;
• cooling the printing substrate web with a cooling device;
• discharging the printing substrate web with a discharge device;
• lubricating the printing substrate web with a lubricating device applying a lubricant in addition to said moistening agent before the discharge device;
• and
• selectively deactivating the buffering device, the smoothing device, the moistening device, the cooling device, or the lubricating device without removing the respective buffering, smoothing, moistening, cooling, or lubricating device from the multifunction device, and wherein the deactivated buffering, smoothing, moistening, cooling or lubricating devices do not influence a function of remaining ones of the buffering, smoothing, moistening, cooling, and lubrication devices which are not deactivated.
