This study examined the RAY dye stain, gentian violet, and alternate powder processes in the successful development of latent prints on the nonadhesive side of tape.

Abstract

This research addresses a new method of processing the adhesive side of tape after it has been exposed to cyanoacrylate fumes. The adhesive sides of various types of tape were processed with gentian violet, alternate powder, and RAY (rhodamine, ardrox, basic yellow) dye stain, following cyanoacrylate fuming. Tests of the RAY dye staining technique were done, both prior to and after processing with gentian violet and alternate powder. The RAY dye stain was the superior method for processing the adhesive side of tape after cyanoacrylate fuming, and the optimal results were obtained after the tape had been processed with gentian violet and alternate powder.
