Streszczenie
In this report results are described of the RTX (ruthenium tetraoxide) method to develop latent prints on cartridges, coins, adhesive tapes, polymeric materials. An advantage of the RTX method is simultaneous visualisation of the latent prints on both sides of the adhesive tape. The prints after the RTX development were compared with prints obtained by other methods (porous surface – cyanoacrylate, sticky surface – sticky side powder). We prefer to use the RTX rather than the cyanoacrylate method for work with polymer materials surfaces. The prints are stable, the friction ridges are conspicuous and contrast is sufficient for taking photographs.
