Questioned document examination is a forensic science discipline in which documents called into question in the legal system are evaluated by a trained examiner. Research has also found that faxes may undergo significant dimensional changes that can result in changes in size or even distortion, further complicating the investigation of transmitted questioned documents. Topics discussed include training and qualifications for forensic document examiners as well as the various methods used to exam differing projects, such as signatures, checks, computer and type generated documents, as well as obliterated writing. It should be noted that handwriting identification or examination is distinct from “handwriting analysis” (graphology), which attempts to predict character traits from handwriting examination. SWGDOC began in 1997, and is composed of private examiners and forensic laboratories throughout the United States.

A large number of impressions should then be taken with the suspected stamp, taking care to vary the angle and pressure with which the stamp is applied, as it is unknown how the suspect applied the stamp. He provides relevant data on the scope of the problem and outlines his involvement in two such cases. A new 3-Dimensional imaging feature for the VSC8000 enables document examiners to derive a 3D model of a documents surface topography in order to better analyse security features, pen-tip strokes and other impressions in paper.
