For manufacturing security documents, a plurality of security documents are printed on a sheet. The sheets are being processed in batches (15a, 15b). Each sheet carries a unique, machine readable identifier. During manufacturing, the batches are processed by several printing stations (10). At each printing station, the identifiers are read by a local computer (13) attributed to the printing station. The results are transferred upon request in data packets to a central data base (16). Each data packet contains the information for several sheets, which obviates the need to transfer the corresponding data in real time over the network. To increase security and decrease network dependence, each local computer is equipped with the means to check the processing status of a batch autonomously.

L'invention concerne la fabrication de documents de valeur, selon laquelle une pluralité de documents de valeur sont imprimés sur une feuille. Les feuilles sont traitées en liasses (15a, 15b), chaque feuille comportant un identificateur unique lisible par machine. Lors de la fabrication, les liasses sont traitées dans plusieurs stations d'impression (10). Sur chaque station d'impression, les identificateurs sont lus par un ordinateur local (13) associé à la station. Les résultats sont transférés sur demande à une base de données centrale (16) sous forme de paquets de données. Chaque paquet de données contenant des informations relatives à plusieurs feuilles, le transfert des données correspondantes en temps réel par le réseau est rendu superflu. Afin d'augmenter la sécurité et de diminuer la dépendance au réseau, chaque ordinateur local est équipé de moyens pour vérifier le stade de traitement d'une liasse de manière autonome.
