Plate management is a critical part of the newspaper production process for which various concepts and solutions exist. An elegant variation, one that covers automatic plate transport including plate changing, is in use in Mannheim, Germany.

Plate production is done in the control room, located beside the press. The photo shows one of two CTP lines: the imager Agfa Polaris XTV-S (in the background) with VXCF 85 washing-out station (in the foreground) processes 220 "chemistry-free" CTP plates per hour.

Positioned downstream from the imager and washing-out station is a video punching and edge-bending unit (VCPevolution) with dual-level sorter-stacker (all from NELA).

Plate output is controlled via the Agfa Arkitex software that receives the production data from the Pecom production control system (manroland). The Arkitex status display informs the operators of the imaging status of all pages belonging to a production run.

The Arkitex softproof display has practically eliminated all hardproofs from everyday production.

An operator removes a set of plates from a storage tray of the sorter-stacker.

The plates are entered manually into the transport cassettes in the loading station of APL logistics, duly sorted in a fixed order. Each cassette is directed to a specific position in the press. Marks indicate to the operator at the loading station how the plates should be positioned, depending on whether they are destined for the lower or upper plate cylinder.

The loaded cassettes leave the control room at the command of the operator. Each rail is assigned to a specific printing unit.
