Features of commercial web offset presses
Eine Illustrations-Rollenoffsetdruckmaschine ist gekennzeichnet durch:
4 or more print units
Typical number of pages: 16, 32, 48, 64, 72, 80 Fix format
Fast exchange of printing plates at production change Printing speed up to 15 m/s
Advantages of commercial web offset
Printing of both paper side in one production step
Several pruducts can be printed with one cylinder In addition to the basic colors also special colors can be printed
Trends Wider and faster machines: 96 pages, 18m/sec
more multidrive functions, especially in the folder, cam curve applications

Printing basics: Offset printing
Offset printing is an indirect print technology where the print color is first transferred
from a mostly thin, flexible aluminum plate to a rubber cylinder and then to the material to be printed.
The four colors cyan, magenta, yellow and black are printed one after the other and finally produce a high-precision color picture.

Requirements Solutions
Higher degree of automation PRINTstandard is prepared for many machine types.
The open architecture allows the add on of own ideas
and new features.
Wider and faster machines Book size: up to 107 kW drive power
Chassis: up to 800 kW drive power
AC/AC or DC/AC drives
Air- , Cold plate- or 2nd level cooling
Wide range of synchronous and asynchronous motors,
torque motors
Self cooled, forced ventilation or water cooled
Commercial web offset Requirements and solutions
Tendency to wider -e.g. 96 paes-, faster -e.g. 18 m/sec- and more automated
machines -e.g. increased number of servo drives in the folder- can be seen
