FIELD: polygraphic engineering.
SUBSTANCE: method for printing of protected documents, in which the latters are printed on sheets, each containing a great number of protected documents. Each sheet has a unique type-readable identifier. In the process of production the lots are processed with the aid of several printing presses. On each printing press the identifiers are read off with the aid of a local computer separated for the given printing press. The results are transmitted by inquiry in the form of poles of data to the central data base. Each pile contains information on several sheets, which eliminates the necessity of transmission of the respective data in the conditions of real time through the network. To enhance the safety of reduction of dependence from operation, each local computer has a means of automatic checkup of the state of the lot processing.
EFFECT: checkout of printing production at a large enterprise at low requirements to hardware, software and computer circuit.
