A comparative study of latent fingerprint development on the adhesive side of adhesive tapes by using various types of gentian violet

Abstract

This study aims to examine the comparison of latent fingerprint development on the adhesive side of tapes by using various types of gentian violet. Four different adhesive tapes included crepe paper tape, duct tape, transparent tape and carton sealing tape, tested with three different commercial gentian violet type (a), type (b) and type (c). The latent fingerprint development was examined by the fingerprint experts through the Automated Fingerprint Identification System (AFIS). The average number of minutiae was then determined by using a two-way ANOVA at a significance level of 0.05. The results of the study showed that the average number of minutiae between gentian violet type (a) and (c) was different with a significance level of 0.05, while type (b) was not different at a significance level of 0.05. For the different types of tapes, the average number of minutiae between crepe paper tape and carton sealing tape was different with a significance level of 0.05. The average number of minutiae on carton sealing tape was higher than crepe paper tape whereas there were no differences with a significance level of 0.05 on duct tape and transparent tape.
