Abstract
Abstract PRESCREENING TECHNIQUES ARE SET FORTH WHICH PRODUCE LATENT PERIODIC MEMORY PATTERNS IN THE DEFORMABLE SURFACE OF A FROSTABLE RECORDING MEMBER. WHEN THE PRETREATED MATERIAL IS LATER USED IN A CONVENTIONAL FROST IMAGING MODE IT IS FOUND THAT THE PRESCREENED LATENT PATTERN DEVELOPS ON THE FROSTABLE SURFACE AND UNDERGOES AMPLIFICATION UNDER THE INFLUENCE OF THE DEVELOPMENT ENVIRONMENT, FINALLY SERVING AS THE MODULATED CARRIER FOR THE FROST IMAGERY IMPRESSED THEREUPON.
