The ribbon analysis workstation (RAW-1) is a computer driven electro-mechanical device designed to enable specialists in questioned documents to transcribe and analyze any of a wide range of multi-row, single-strike, carbon film ribbons. The time consuming method of manually reading a single-strike ribbon makes the introduction of the RAW-1 a unique labor saving instrument. This study examines the accuracy of the RAW-1 in reproducing an accurate transcription of an original text from a carbon film ribbon. Ten single-strike ribbons, with a predetermined text of ten thousand words, were processed on the RAW-1. The texts from the ribbons were then compared to the printout from the RAW-1 for accuracy and repeatability.
