The display of handprints on a trace-receiving surface depends on many factors - the physical and physico-chemical properties of the surface of objects, the composition of the sweat and grease substance, external conditions and the mechanism of trace formation. The completeness of the identification of particular signs and signs of the papillary line in latent handprints using methods traditionally used by forensic experts during inspections of accident scenes and in laboratory conditions, has a significant impact on the result of fingerprint examinations and studies. The article discusses and clearly illustrates the results obtained during experimental work on the identification of latent handprints formed on various trace-perceiving objects containing poro- and edgeoscopic signs using physical, physico-chemical methods and appropriate technical and forensic tools. Recommendations have been developed that will be useful in practical forensic work.
