Charge coupled devices Alteration in the surface and change in chemical composition of paper. c. Everyone involved in the case Non-destructive examinations, such as visual, microscopic, ultraviolet, and infrared tests are usually the first step taken in an effort to identify the class of ink used on a document. In this article, forensic document examiner, Mark Songer provides an overview of forensic document examination. Some fax machines also allow the user to reprogram certain formatting characteristics, which may make it more difficult to accurately discern the make and model of the source machine. Given the poor quality of faxes in general, they are subject to alteration, however, so careful scrutiny should be applied to any discrepancies in pixilation across the document, as well as any variations in handwriting or print type, spelling, punctuation or formatting. Handwriting Comparisons 2. Using an unqualified document examiner can potentially result in the expert being excluded from testimony and the evidence being considered inadmissible in court. Albert Sherman Osborn is considered the father of the science of questioned document examination in North America.. His seminal book Questioned Documents was first published in 1910 and later heavily revised as a second edition in 1929. In one method, known as reflective UV imaging, the wound is flooded with UV light, and the reflected UV image is photographed.

Relation to other things Types of Document Examination 1. Obliterations or overwritingthe blocking out of portions of writing using some opaque materialalso may be used to obscure writing or other information on the questioned document. Forensic examiners also evaluate paper documents for internal or surface weaves. The Scientific Response and Analysis Unit provides end-to-end case support, from initial assessment of investigative or intelligence information, "hot zone" capable scientists, crime scene processing and collections, evidence examination, and courtroom testimony regarding: Remember: Dyne is a metric to measure the surface tension (dynes/cm). An exemplar is an example or sample of a genuine document. Previous research has totally focused on development of science and technology. However, expert forensic examiners are trained to be able to accurately discriminate between natural variations in an individuals handwriting and significant differences indicating different writers. On the other hand, watermarks made during the manufacturing process produce very light and diffuse marking that isnt visible unless you see through a brighter background. Photography with reflected light. in order to determine if a crime occurred and help solve it. Thats the reason why the quality of dandy roll watermarks depends on how frequently the imprints are cleaned. UV light provides more detail and contrast to an injured area, including bite marks, than standard lighting techniques. Use covers or envelopes that are large to hold the document without folding. The relatively poor quality of faxes and photocopies, in comparison to the original document, means that they may be particularly susceptible to manipulations or alterations for fraudulent purposes. They are majorly seen in chemical watermarks that are manually marked. Typical strategies employed when someone is attempting to disguise their handwriting include changing the slope of the writing or lengthening the terminal strokes and adding curves or other embellishments.

Furthermore, defects to these raised patterns are highly individualistic. The drones are male bees. Required fields are marked *. Next, it should be established whether the questioned document is an original or a reproduction, and whether there were multiple printing methods involved in the creation of the document (e.g., a printed document that was then photocopied and/or faxed). Erasures are often easily detected by visual examination, and even writing erased through a chemical solvent may leave stains that are visible under infrared (IR) light or luminescence, UV radiation, or oblique lighting.

Questioned Document Examiners use a special form of photography combined with ultraviolet and infrared light to detect erasures, alternations, and obliteration that are hard to detect with naked eyes. a. This can be achieved by 3D relief on the roller itself (not on the wire). Internal weaves are more commonly found in paper and can be viewed with transmitted light. Scanner: Capture detail with a specific resolution. b. Digital photography The use of electronic means to capture light and save and image on an electronic medium such as a memory card Film speed The measure of ease with which the silver halide grains of a given film react to light Single lens reflex (SLR or DSLR) camera Peer group testing is also available through the American Society of Forensic Document Examiners (ABFDE) and the Forensic Science Society (FSS). When comparing handwriting from collected specimens, however, it is important to collect contemporaneous writing, or material that was written around the same time period as the document in question.
