PECULIARITIES OF RESEARCHING FADE-OUT PRINTS (STAMPS) USING THE VIDEO SPECTRAL COMPARATOR VSC 40

Abstract

The purpose of the article is to develop, based on the analysis of theoretical provisions and practice,
the introduction of effective tools to expand research opportunities proposals and practical recommendations for the use of video spectral comparator – VSC 40 in the study of extinguished seals (stamps). Methodology. The of
the obtained results and conclusions is ensured by the application of a set of general scientific methods of cognition. Thus, thanks to empirical methods such as observation, descripti highlights functionality of VSC 40, and the use of a wide range of experimental methods allowed to test the capabilities of the video comparator to tasks of forensic technical examination of documents including the study extinguished imprints of seals (stamps). Theoretical general scientific methods of cognition, in particular analysis, synthesis, generalization, provide the process of research of extinguished texts at its various stages. The use of an empirical method of comparison made it possible to assess the advantages of research usingwith the a video spectral comparator compared to traditional methods. Scientific novelty. Made аttemptan to justify the need to find effective tools to expand research opportunities in the study of eextinguished prints of seals (stamps) on the example of using a video spectral comparator – VSC 40. Conclusions. In the process of approbation experimental researches of eextinguished prints of seals (stamps) the possibilities of using VSC 40 are illustrated – from visualization of prints to comparative identification studies as by general (overlay, biascomb of prints of current and saved images, including with their color separation) and individual featur (search for convergent and divergent featur displayed on the monitor of both saved comparable prints). The same time it is statedat the process of research of extinguished seals (stamps) with VSC 40 is automated and less cumbersome, thanks to a wide range of functions of the videocomparator whatallows saves time and money when tackled solving the same type of tasks, with while complementing traditional methods research. In addition, it is proved that even invisible prints of seals (stamps) exposedare subject to television visualization, and the very fact of restoring records and images (visualization) allows within the forensic technical examination of documents to resolve diagnostic character issues to establish the initial content imprint. It is emphasized that the practical recommendations expressed in the process of presenting the main material on the use of VSC 40 in the study of extinguished seals (stamps) can serve as a basis for the development of appropriate metodik guidelines.
