The Examination and Demonstration of the Presence of Paper Fiber Patterns on Carbon Film Ribbons Using the Ken-A-Vision® Video Flex® Digital Camera

Forensic Document Examiners (FDEs) often utilize various instruments to assist them in the examination of questioned documents and to prepare demonstrative charts to illustrate their findings. Unfortunately, many of these instruments are uneconomical and are limited in their capabilities in that they can only be used for a single purpose. Recently, a more versatile instrument, the Ken-A-Vision® Video Flex® digital camera, has become available and is finding its way into the arsenal of the forensic scientist. Utilizing the Video Flex®, the authors tested a new method for the examination and demonstration of paper fiber patterns on carbon film ribbons. This device not only assisted the authors in their examinations, but also provided a means to easily demonstrate the subsequent findings.
