Introduction
The development of latent impressions on adhesive surfaces is a relatively new technique, as noted in a 1994 article in the Journal of Forensic Identification entitled "StickySide Powder: The Japanese Solution" and also in a 1997 article in Fingerprint Whorld entitled "Development of a Black Powder Method to Process Adhesive Tapes." Both methods are easy and achieve extraordinary results.
However, realizing a common element within the two techniques, I researched and tested additional powders using Photo-flo and Liquinox detergent on selective surfaces. These powders are Lightning Pink-wop Fluorescent Powder and Sirchie White Fingerprint Powder. These methods also were easy to use and achieve excellent results.
