D Moryan · Journal of Forensic Sciences · 1995
Abstract Provided with overwritten carbon paper images and one carbon copied document produced by the carbon paper, decipherment of the overwritten entries can be made. A technique using the Video Spectral Comparator with the Image Integration Comparator can reveal overwritten entries by storing and superimposing images of the carbon paper and carbon copied document.
