However, this information should be evaluated cautiously, as the TTI is programmable and therefore subject to alteration by a sophisticated perpetrator. Questioned Documents was published in 1910, and a second edition in 1929. 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. Once this is accomplished, the examiner may turn his or her attention to the specific nature of the markings, specifically noting any defects that may be unique to an individual stamp. These develop into adult drones. 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. In forensic science, questioned document examination (QDE) is the examination of documents potentially disputed in a court of law.Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods.

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 Transmitted faxes are often printed at a relatively low resolution, compared to documents that are printed or photocopied. This can be achieved by 3D relief on the roller itself (not on the wire). Traditionally, the flexo chemical watermarking technique was widely used. Led research study on assisted and guided hand signatures of bedridden and elderly subjects, NADE. The second important use of photography in document examination is for recording and presenting evidence. 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. The inks composition can then be compared to the International Ink Library, a database of more than 9,500 inks that is maintained by the U.S. Secret Service. Simulated Writings and Tracing b. The goals of SWGDOC published on their website include: Strengthen the content and the enforcement of published performance standards. 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. Lets look at how these types of watermarks aids questioned document examiners (QDEs) in their examination of the paper. This technique has resulted in the recovery of indented impressions on paper up to seven layers beneath the original writing, though findings may vary depending on pen pressure and paper thickness. Revised and expanded to reflect the most recent innovations in the field, The Scientific Examination of Documents, Fourth Edition is a handy, accessible volume detailing current best-practices for forensic document examination.

It is critical that the document examiner obtain multiple samples of an individuals handwriting for comparison to any questioned document, as natural variations will always be present in a persons handwriting, even within the same document. T/F The higher the camera's f-number, the greater the depth of field of its photos. They collect nectar and pollen, convert it into honey, raise the young, and build their honeycomb. Typewriters c. Notes should include location of each item of physical evidence that is recovered. c. High f-stop For example, it may be the case that a page is substituted in a will that is printed on paper or with ink that was not available at the time of the original signing. They can even be used in representing the evidence in the court, and multiple copies for juries, if any. Simulated writing occurs when an individual attempts to copy the handwriting of another by making a freehanded drawing of the writing or by tracing authentic writing. Indented writing on subsequent pages may not be the same as what appears on the surface of the document. Applications of Questioned Document Examination Document Examiners have a crucial role to play in investigations involving a documentary evidence. Consolidate and enhance the profession of forensic document examination. d. the notes are recorded as the observations are made. When faced with a computer-generated document, the investigator first attempts to classify the printing process by identifying the printing technology. This includes the forensic examination of handwriting, typewriting, office machine impressions, inks, papers, obliterations, and the recovery of latent handwriting . 7. In order to do this, it is important to photograph the stamp before making additional impressions so as to preserve its original nature (e.g., ink saturation, dirt, fibers). The edges of chemical watermark smudges with time. These chemicals are very individualistic based on their composition and type of printing process. An individual attempting free-handed simulation of writing strives for both accuracy of shape and proportion, and fluency of line; however, it is nearly impossible to achieve both.

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). Whenever possible, the forensic investigator should examine the particular machine(s) suspected to have been used in creating questioned documents in order to compare individual characteristics. 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. Further destructive testing may also be necessary to discriminate among ink types. In general, people vary in their ability to produce an effective freehand drawing of writing or a signature.
