A Further Evaluation of the Electrodeposition of Gun Blue (eGB): Part 1- Fingermarks

Previous publications by Dove showed that adding an electric charge to a metal substrate when developing fingermarks using gun blue improves the contrast and quality of the resulting fingermark development compared to both the passive gun blue version and the other standard development techniques.

Summary:Previous publications by Dove showed that adding an electric charge to a metal substrate when developing fingermarks using gun blue improves the contrast and quality of the resulting fingermark development compared to both the passive gun blue version and the other standard development techniques. This paper performed a deeper analysis of the electrodeposition of gun blue (eGB) by examining the sensitivity of the technique to external factors, including the impact of the donors, matrix, substrate, and age of the fingermark. The study showed that the eGB performed well and was surprisingly resistant to external variations.
