Abstract
Introduction. Due to the criterion of recoverability, the dot peen marking is widely used as a protective one for such products as, for example, firearms or locking and sealing devices. However, in forensics, the possibilities of establishing the commonality of origin of such markings and identification of specific equipment have not been investigated. Theoretical analysis. To solve these expert problems, a proven approach was chosen, which consists in studying the constructive and technological properties of dot peen markers as objects of forensic research. Empirical analysis. In the real production cycle of serial sealing devices, markings were made on 20 Pinstamp TMP1700 markings installation. In total, more than 90 products of several model ranges were examined. The main attention was paid to the display of group features of the image program (template); display of individual signs of a particular installation and stability of feature display. Comparative analysis showed that in the marking traces there is a complex of stably displayed group and individual signs of the technological installation. Results. The study of the identified complex of features allows you to establish the production origin of the dot peen marking, the software settings of the template and individualize a specific marking installation.
