Abstract
Documents are printed in accordance with sets of printing instructions. To a processing station, processing instructions are supplied, each associated with one of the sets of printing instructions. The order in which the processing instructions are executed corresponds with the order in which the sets of printing instructions are executed. Printed documents are supplied to the station, which processes the documents in accordance with the processing instructions whose turn is next. In order to check the processing of the documents, starting from one of the printing instructions, associated verification data are determined. The printing on the printed documents is scanned, whereby a scanning result is obtained. A scanning result is compared with verification data of which the associated sequence information corresponds with the sequence information assigned to that scanning result. If too large a difference is found, a difference report signal is generated. Also described is an apparatus for carrying out the method.
