ASTM International is a global leader in the development and delivery of voluntary consensus standards, to improve product quality, enhance health and safety, strengthen market access and trade, and build consumer confidence. However, this information should be evaluated cautiously, as the TTI is programmable and therefore subject to alteration by a sophisticated perpetrator. b. Bracketing Most charts today are created using digital photography, scanned images, video spectral comparators, and specialized computer software programs like Write-On 2, Photoshop, and PowerPoint . They do allow an investigator to view the document without adding any additional fingerprints or impressions. Resolution How did World War I help to bring about the Russian Revolution? They may also result in roughened or disturbed paper fibers and impressions of the original writing, and ink written over erased areas tends to bleed slightly and spread.

Forensic Document Examination helps answer questions whether the note was written by the deceased or someone trying to manipulate investigators? b. Document Security Integrity, the importance of watermarks in . The preliminary visual inspection of a stamp impression is to examine it microscopically, during which time the examiner may be able to identify a number of factors, including the ink source and condition of the ink die. Although structural characteristics are often still evident, subtle details, such as hesitations, pen lifting, and retouching may not be reproduced. But they are not good for personal or small business use because you have to contact paper manufacturers for special orders (which are usually in bulk). Photocopy Analysis 7. Indented writing on subsequent pages may not be the same as what appears on the surface of the document. Relation among its parts 5. 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. Questioned document examinations involving facsimile (fax) machines often include questions around the authenticity of a reproduced signature, concerns around whether information has been altered, added, or deleted from a document, or questions about exactly when a fax was transmitted.

Transmitted faxes are often printed at a relatively low resolution, compared to documents that are printed or photocopied. It is sometimes possible to remove the obliterating material using an ordinary rubber eraser, chemical solvent or scraping off the overlying layer, although pains must be taken not to damage the underlying writing. Questioned documents on issues of materials used in their production. It should be noted that handwriting identification or examination is distinct from handwriting analysis (graphology), which attempts to predict character traits from handwriting examination.

In natural writing, the writer is likely to have a strong fluency of line- meaning the pen will rarely, if ever, leave the paper while writing a single word or signature. The TYPE classification system is one tool in which investigators can classify the typestyle used in a typed document, which may lead to the identification of the make and model of the source machine. Their concentration and composition determine the extent to which they can create opacity. So, with each rotation of the dandy roll, the fiber accumulation increases, resulting in a relatively more opaque watermark (transmit less light) than the rest. 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. Watermark is a distinctive form of image, shape, text, or any design that appears translucent and fainter when light passes through it. Silver halide grains B.

Questioned document examination is a forensic science discipline in which documents called into question in the legal system are evaluated by a trained examiner. When these watermarks appear in the questioned documents, they can state origin, manufacturer, retailer, and possibly the manufacturing date. The increasingly ubiquitous use of computers resulting in computer-generated documents has resulted in difficulties for the questioned document examiner. The examination's primary purpose is to provide evidence about suspicious or questioned documents using a variety of scientific principles and methods. More recently, an instrument known as an Electrostatic Detection Apparatus, or ESDA, is used to produce a visual image of the indented writing on transparency film.
