Abstract
Vacuum metal deposition(VMD) using gold and zinc is known as a very sensitive technique of developing latent fingerprints on nonporous surfaces by excellent malleability and ductility of gold. However, VMD produces empty print which cannot be identified. There is only presumption about the cause of occurrence of empty print, the exact cause is not known. In this study, we experiment on the freshness of fingerprints and sensitivity of techniques that are estimated as the factors causing empty print, based on this, we suggest cyanoacrylate fuming is effective to redevelop empty print.
