Abstract

The purposes of this research were to compare the quality of latent fingerprints on various types of paper including white copy paper, kraft paper, thermal paper and corrugated paper using Ninhydrin versus using Indanedione followed by Ninhydrin and to compare the efficiency of latent fingerprint detection of Ninhydrin versus Indanedione followed by Ninhydrin. The quality of the latent fingerprints was evaluated by a latent fingerprint expert and based on the number of minutiae. Data were statistically analyzed using means, standard deviation and two-way analysis of variance (Two-way ANOVA).The results of this research showed that detection using Indanedione followed by Ninhydrin provided the best quality of latent fingerprints on all types of paper, which was at the “Good” level. When testing the hypothesis for both factors, it showed that the types of paper and the method of latent fingerprint detection significantly affected the quality of latent fingerprints at 0.05.
