Papillae pattern prints play an essential role in identification of a person. However, their presence on the object found at the scene does not mean that the identified person committed a specific crime or participated in the concealment of the crime. Therefore, no less important is the object on which there are possible papillae pattern prints left, the mechanism of formation and location of them on the object. The skin of a victim, on which one can visualise the papillae pattern prints, can be one of such objects. However, there is a number of factors that may affect the genesis of papillae pattern prints on human skin that one cannot have an impact on. Identifying study and analysis of such factors may affect testing and introduction of visualisation methods of such prints. Papillārlīniju rakstu pēdām ir būtiska loma personas identifikācijā. Tomēr to atrašanās uz kāda objekta, kas atrasts notikuma vietā, vēl nenozīmē, ka identificētā persona ir izdarījusi konkrēto noziedzīgo nodarījumu vai ņēmusi dalību noziedzīga nodarījuma slēpšanā. Tāpēc ne mazāk svarīgs ir objekts, uz kura ir atstātas iespējamās papillārlīniju rakstu pēdas, un jautājums, kāds ir pēdu veidošanās mehānisms un izvietojums uz objekta. Viens no šādiem objektiem varētu būt upura āda, uz kuras ir iespējams vizualizēt papillārlīniju rakstu pēdas. Tomēr pastāv vairāki faktori, kas var ietekmēt papillārlīniju rakstu pēdu ģenēzi uz cilvēka ādas un kurus mēs nevaram ietekmēt. Šādu faktoru apzināšana, izpēte un analīze varētu ietekmēt šo pēdu vizualizēšanas metožu aprobēšanu un ieviešanu praksē.

The authors of the article conducted a comparative study to determine the incidence frequency of various papillary patterns in men and women. In the framework of this study, the authors collected and performed analysis on data published in the subject literature. Comparative analysis was performed to check for potential similarities and differences in papillary patterns, types, and groups in men and women, using data on the patterns in both hands. This article presents the results of the study.

The article gives a brief overview of the types of papillary ridge patterns of the skin, their location on the digits of fingers and toes. In this study, the authors of the article aimed to determine whether the papillary ridge patterns of a person’s fingers and toes on the hands and feet of the same side are identical in terms of general characteristics. The methods used were the printing ink imprints on dactyloscopic maps and Microsil® impressions, and the comparison of the obtained impressions.
