Security control procedures are described for recruiting personnel for a printshop manufacturing banknotes and security documents, the comings and goings of personnel and raw materials and the finished product, and systems for recording any undesired intrusion upon the facility. Control procedures are also described for receiving and storing paper and ink at the printshop. Security for original equipment used in manufacturing banknotes and security documents is also discussed. Processes and examples of criminal cases recorded are described for the following categories of imitations: total imitation using the original and auxiliary processes, look-alike counterfeits, and alteration of the contents of a document (forgeries). Noting that for several years, electrostatic color copiers have posed a security problem, advice is given on incorporating effective protection measures, either when manufacturing the printing form or selecting the inks. Measures which can be taken at the printing stage to prevent counterfeiting are described, including proportioned lathework, simultaneous printing, and the intaglio printing process. Photographic illustrations are provided. For part one of this presentation, see NCJ 80024.
