Abstract
Inkless skin printing apparatus and method featuring unique cooperation of common, harmless, odorless solvent in association with ordinary thermal (fax) paper material. The skin area is coated with a substance which includes the solvent and then impressed onto and withdrawn from the thermal paper, thereby visibly forming a developing impression on the thermal paper which eventually fully develops into a quality skin print. Heat application to the developing impression may serve to accelerate and/or enhance the development. Skin prints such as fingerprints are generated according to this invention with 'no muss, no fuss, no-clean-up-required' neatness and efficiency, and if desired with on-location portability.
