Abstract

Highlights: A collaborative exercise was carried out in 2017 within ENFSI EFP-WG. The Visualisation Test was focused on ninhydrin. Ninhydrin fingerprint development as a methodology is robust. Test stripes from solutions of known composition is preferred for proficiency testing. Abstract: In 2017 the Fingerprint Working Group (EFP-WG) of the European Network of Forensic Science Institutes (ENFSI) undertook a collaborative exercise (CE) with the aim of assessing the use of ninhydrin as a fingermark development technique in the laboratory. The test was prepared and managed by the officially established advisory group. The characteristics of the CE are summarised. The results indicate that ninhydrin is a robust methodology. Unexpected negative outcomes have been outlined and discussed, followed by an overview of the knowledge that has been gained.
