Indented writing on subsequent pages may not be the same as what appears on the surface of the document. A document examiner, trying to determine if the document has been altered by chemical methods, would use which of the following? The increasingly ubiquitous use of computers resulting in computer-generated documents has resulted in difficulties for the questioned document examiner. Therefore, when faxed documents are called into question, both the source and receiving fax machines should be entered as evidence, as well as sample faxes from both fax machines transmitted around the date established by the TTI. As compared to a freehand copy, tracing a signature often results in a very close approximation of the original; in fact, they may provide a more exact copy of a signature than would normally be found due to natural variations in handwriting. Photograph serves as permanent records of questioned document. 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. c. Everyone involved in the case 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. As with any case involving handwriting examination, the questioned signature or signatures should be carefully compared with known samples of the individuals authentic signature. Using an unqualified document examiner can potentially result in the expert being excluded from testimony and the evidence being considered inadmissible in court. They are primarily used to authenticate secure documents. 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 .

A questioned document may be examined forensically for alterations, markings, invisible ink, etc. Forensic document examinations should be conducted by a Forensic Document Examiner (FDE or Document Examiner). Random Watermarks: They are randomly placed on the page. Abstract The questioned document examiner studies letter design and size on two or more documents. Please note, the following information must be used only for educational purposes. When faced with a computer-generated document, the investigator first attempts to classify the printing process by identifying the printing technology. c. Notes should include location of each item of physical evidence that is recovered. Since the introduction of the ESDA in 1978 foster+freeman have been recognized as world leaders in the field of questioned 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. Paper Analysis 6. Gun Shot Residues/Explosive Residues There are several different types of residues found both in ammunition and explosives, This impression of the writing is influenced by pen pressure and thickness of the paper. 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. b.
