    Abstract

    The implementation of a technique, utilizing an arc lamp and filters, designed to reveal latent text impressions on typewriter and printer platens. This technique allows for the location and decipherment of text on platens which are undetectable utilizing conventional sources (for example, side light techniques, VSC-1, etc.).
