CONCLUSION
The conventional fingerprint powders (non-magnetic, magnetic,
and green fluorescent) utilized in this research were very effective in
developing prints on the non-porous substrates chosen for study. The
upconversion powder sufficiently suppressed the background luminescence and the infrared laser demonstrated strong illumination. However, when the developed conventional powdered fingerprints were
compared to the same print developed with upconversion powder, the
same level of detail and clarity was not apparent. For this research, the
conventional fingerprint powders proved to be the superior development methods for aged latent fingerprints. The upconversion powders
have the potential to be a good method of development, especially on
luminescent and multicolored substrates, but additional research and
modifications would be necessary to improve upon this method. It
can be concluded that the conventional powders were more effective
in developing and highlighting the prints.
