Abstract:
1. A method for processing document data in a document processing computer that comprises at least a document generation computer, a document processing computer, a printing system, at least two document inserting devices each of which inserts documents into envelopes, and a monitoring system, comprising the steps of: generating document data on the document generation computer by means of a document generation module; transmitting the document data from the document generation computer to the document processing computer and processing the document data there, the processing computer analyzing the document data job-by-job concerning their size with respect to a selectable parameter, and dividing a job into at least two partial jobs each comprising a segment when the job exceeds a predetermined size; adding page control data for each printed page of the job in the processing computer by means of a processing module, and with the processing module storing the page control data; also adding segment control data to the document data in the processing computer with said processing module via which print stock generated from the document data are separately processed segment-by-segment in subsequent processing steps, and wherein in each partial job said segment control data describing a beginning and an end of the partial job are respectively added to each of the partial jobs at only the beginning and only at the end of the partial job; forwarding a document data stream with the document data, the page control data, and the segment control data generated by the processing computer to the printing system for output of a print stock for each of the partial jobs in one or more stacks, and wherein said respective segment control data identifying said beginning and said end of the respective partial print jobs are printed only on respective documents at a beginning and an end of each partial print stock and the respective page control data is printed on each respective page; in a later processing of the print stock stacked in said one or more stacks, the page control data are read from the print stock stack with an automatic read device and are communicated to said monitoring system; as soon as the monitoring system determines based on said stored page control data and the read stack page control data that an error has occurred in the print stock, the monitoring system sends a notice back to the document processing computer and the document processing computer resupplies a corresponding document data for reproduction to the printing system to correct said error; processing segments of said job simultaneously at said at least two inserting devices, wherein at least two of said automatic read devices are provided and wherein each of said inserting devices has one of the respective automatic read devices, and wherein at each of the respective inserting devices the print stock is loaded into the respective inserting device, the respective read device reads the printed page control data and a corresponding release request is directed to said monitoring system for the processing of the print stock, if the corresponding job can be processed, the monitoring computer issues a release, and the respective inserting device is started; and by analysis of the read printed page control data, generating a stop command if a document appears at one of the two inserting devices that was already processed at the same inserting device or the other inserting device.
