Definitions

  • the invention relates to a printing press and a method for printing on two webs.
  • a printing press is known from DE 100 15 703 A1, in which two webs are guided back to back through a plurality of double printing units and are each printed on one side. Each web can be guided around one of the double printing units, which allows the other web to be printed on both sides.
  • DE 18 27 845 U shows a path which is optionally carried out between two transfer cylinders or between a transfer cylinder and an associated forme cylinder.
  • CH 657 313 A5 discloses a web guide through a printing press, each of two webs being printed by a direct printing process through a plurality of printing points formed from transfer cylinders and forme cylinders. In this mode of operation, the transfer cylinders of mutually adjacent printing units are shut off from one another, and the webs are guided separately through the printing points.
  • EP 0 919 373 A1 describes a printing press for printing two at the same time Webs are known, two webs being guided back to back through double printing units and printed on one side. Each of the webs is then individually printed on one or both sides by a further offset printing unit.
