    Abstract

    The carbon copy document is one form of physical evidence that has not received much attention. Although the classical techniques employed to differentiate typewritten documents are often adequate to differentiate carbon copies, the following work suggests an additional technique. Thin-layer chromatography has been used to differentiate many color-containing mixtures, and its usefulness in differentiating carbon paper impressions is discussed.
