This study investigated the development and effectiveness of a dark iron magnetic flake fingerprint powder.
Abstract
Highly reflective magnetic iron flakes are suitable for visualizing latent fingerprints on dark, textured surfaces. However, there is a need for a darker variety of this magnetic flake powder that would be suitable for obtaining good contrast on light background surfaces. A novel dark magnetic flake powder was therefore developed by vibration milling, and the powder was then evaluated for latent fingerprint development. This evaluation indicted that a darker variety of magnetic flake powder, obtained by dry milling with an optimum stearic acid, provided good-quality results for fingerprint development.
