Principle of development: it uses a special sheet that has a denser area where the design will impress than the rest of the paper. Surface weaves are uncommon but are easily visualized with side lighting. Documents that contain indented impressions not visible to the naked eye may be recovered through the use of an Electrostatic Detection Device (EDD) and oblique lighting photography. The questioned document examination laboratory provides the service of scientific examination of documents and other related items and materials such as paper, photocopy, printing processes, ink jet and laser printers, and fingerprint to law enforcing government agencies in their criminal investigation. Detection of alternations includes, but are not limited to: Current standards for document examination are established by the Scientific Working Group for Forensic Document Examination (SWGDOC) which is composed of private examiners and government examiners from local, state, and federal laboratories throughout the United States. The organic analysis and instrumental analysis (IR) can evaluate the groups that are involved. When page substitution is suspected, the date of writing or printing also should be evaluated, as chronological inconsistencies can be useful in discrediting questioned documents. 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 the early 1980's, master forger Mark Hofmann added chemicals to documents to make the paper and ink look older. Some of the eggs the queen lays are unfertilized. No randomness is seen.

Melting the polyethylene glycol, by heating the printed paper to 60 C. Melting soaked polymer into paper, resulting in a translucent area. The National Association of Document Examiners (NADE) also was established in 1979 to promote the interests of document examiners. In printers, they are measured by applying wetting tension liquids to paper in order to analyze print-ability, coating lay down, and heat sealability of treated films. A side-by-side comparison can then be conducted with the questioned impression, and conclusions as to the source of the impression may be made. b. Quick history: They were made by John Marshall in 1826. Origin 4. Facsimile and Photocopy Machines a.

Tracing paper may be placed over the genuine writing or a light box may be used to illuminate the underlying writing so that the overlying paper may be traced upon. For a discussion of the technical aspects of the medium . Embossed watermarks involve processes of imparting the design when the sheet is nearly dry using an engraved (deep), in-steel roll compressing fiber. The investigation is usually initiated in the event that. T/F Single lens reflex (SLR) and digital single lens reflex cameras allow the photographer to manually select the resolution. This process typically culminates in the presentation of gathered evidence at preliminary hearings, pretrial depositions, or in a courtroom. with the examination of the questioned writing, these additions may produce a certain amount of confusion and tend to delay the laboratory examination. Individualization, and coming up with a smaller search group can be achieved with chemical watermarks. Photography Scholarship, DAI. Tracing a signature or handwriting can be achieved through a number of means, assuming the individual has access to an authentic sample of writing. 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. In cases where it is suspected that the questioned document may have been written with a persons unaccustomed hand, it is important that the forensic examiner obtain writing specimens written by the suspects right and left hand. The enlarged photocopied provides an extensive detailing of a part of the document. Moreover, the extent of pressure is responsible for the watermark opacity. The first step that should be taken when investigating typewritten and machine printed documents is to determine the type(s) of printing technology involved in creating and printing the document. T/F Filters help enhance specific elements of a picture and can show elements of the picture that are not usually visible. This article is an excerpt from Practical Applications in Forensic Science, authored by Mark Songer, published by Crime Ink Publishing, LLC.

While differentiation among inks can be accomplished by visual examination, nondestructive, and chemical tests, positive identification of the specific source of the ink (i.e., the exact pen) is unlikely. Random Watermarks: They are randomly placed on the page. White balance For example, the examiner determines whether the document was printed in color or black-and-white ink, whether the document was printed with ink or toner, and whether the printing process was impact or non-impact.
