Abstract

A method of obtaining an optical image of a skin-print on an absorbent substrate having a skin-print receiving region. The method comprises: depositing a solution of a silver- containing compound having a solubility in water of at least 10 g/l on the skin-print receiving region of the absorbent substrate such that between 25 μg and 300 μg per cm2 of the silver-containing compound is deposited, and allowing the substrate to dry. The method further comprises: depositing a skin-print on a skin-print receiving region of the substrate such that sodium chloride and water in the skin-print react with the silver-containing compound to form silver chloride; exposing the substrate to electromagnetic radiation such that the silver chloride decomposes to form metallic silver; taking an optical image of the pattern of the metallic silver; and releasing a buffer solution onto the substrate. The buffer solution comprises a counterion for silver, which reacts with the silver-containing compound to form an compound of silver having a solubility in water of less than 1 g/l.
