Modular digital printing press with linking perfecting assembly

Abstract From the Canadian patent

Modular printing apparatus wherein multiple central-impression presses may be linked to one another either, directly or through a perfecting assembly that reverses the facewise orientation of cut sheets. The presses each contain circuitry defining a signal and control path for the press and a plurality of electrical contacts that renders the path accessible and facilitates serial connection of the presses without disruption of the path. At least one of the presses includes a port for receiving connection to a controller, which thereby engages the signal path and via the path, operates the presses independently or together as appropriate. The system includes a connector that is used to …
