The aim of this research project is to study the use of paint electrodeposition to enhance fingerprints on a brass metal surface. High throw power paint was used in the initial studies; high throw power paint is formulated to coat the surface of the metal discs as well as any pits or crevices in the surface. These initial studies showed that commercial high throw paint had a tendency to cover not only the bare metal surface, but the fingerprint residue. In the next round of studies, adjustments to the formulation to lower the throwing power were made. Results from fingerprints deposited on brass surfaces showed modest increase in enhancement by dilution of the paint and changes in the paint morphology upon adjustment of the binder and non-aqueous components.
