Optimum Conditions for Examination of Documents Using an Electrostatic Detection Apparatus (ESDA) Device to Visualize Indented Writings

CODEN: JFSCAS

Abstract

This study indicated that preconditioning a document in a humidity chamber maintained at 40 to 60% provided the most information from indented writings. It further indicated that aerosol application of the toner provided more information than cascade application. This study also indicated that electrostatic detection apparatus (ESDA) examination for indented writing has no deleterious effect on subsequent latent fingerprint development.
