Chemical Processing of Fingerprints on Thermal Paper
… muriatic acid and acetic acid fuming develop the thermal side of thermal paper using aged prints. Additionally, the research seeks to determine how well ninhydrin develops the paper side of thermal paper using aged prints after exposure to the fuming. Twenty-four random individuals placed a total …
