Modern high-technological methods of forging overprinting seals and stamps in documents

The article analyzes the features of modern high-tech methods for counterfeiting overprinting of the seals and stamps in documents. All of them reflect the technological features and technical equipment current time in which they were invented and actively used. The authors pay special attention to the physical modeling of printing plates from overprinting of seals, computer modeling of digital images of overprinting took from the sealing, as well as the manufacture of counterfeit printing plates from digital camera-ready copies of the overprinting obtained in the process of computer simulation. The paper considers approximate sets of features characterizing various high-tech methods of counterfeiting overprinting of the seals and stamps in documents. In preparing the article, general-scientific methods of empirical knowledge (comparison, description), general-logical methods of analysis, synthesis, generalization, classification, as well as methods of systemic-structural analysis were used. The purpose of this study is to demonstrate the detected signs that characterize modern methods of counterfeiting overprinting of the seals and stamps in documents. The article’s conclusions are practically oriented and will enhance the detection and investigation of crimes committed using sham papers.
