Abstract :Forensic document examiners come across various documents whose authorship is a matter of controversy. Forgers are using printing devices to produce fabricated documents. Genuine documents may also contain alterations such as additions, interlineations, obliterations, etc. This may put a question on the authenticity and authorship of that document. Establishing the chronology of printing and signing is an important task. In this study, the chronological order of intersections between various printed or typewritten strokes and different writing instrument ink strokes has been determined. In this study, 8640 samples were prepared, of which, 4320 samples were printed after writing and the rest 4320 samples were printed before writing. The samples were analyzed under Infrared light using Projectina® DocuCentre Expert. A blind test was performed to verify the results. The technique gave helpful results for a few combinations.
