Indented Writing Analysis For a discussion of the technical aspects of the medium . Photography Scholarship, DAI. However, more sophisticated insertions or alterations require careful examination of the document as a whole to identify discrepancies. The exposure compensation settings on a digital camera would be used to capture an image that is: 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. . Photocopy Analysis 7. Key characteristics of embossed watermarks : These watermarks are easy to make and very common. Resolution 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. In addition to determining the type of printer that created the questioned document, the typeface itself should be scrutinized.

Watermark is a distinctive form of image, shape, text, or any design that appears translucent and fainter when light passes through it. Internal weaves are more commonly found in paper and can be viewed with transmitted light. Previous research has totally focused on development of science and technology. The importance of ink analysis has been noted in case of obliterations for differentiating the ink on basis of its chemical composition; further, the source and also the age of ink which ultimately gives the approximate age of the document providing leads and clues in the investigation process. Thickness may be measured by using paper calipers or micrometers, while weight may be measured by using a very sensitive scale.

Any examination involving typewriting should include an evaluation of the class of typewriter, horizontal spacing, typestyle and make and model, and individual characteristics and defects. Quick History: Watermarks used in Europe for the first time. 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: The lens opening that allows light into the camera. Document Security Integrity, the importance of watermarks in . 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). Any. Alterations 5. b. Relation among its parts 5. Abstract The questioned document examiner studies letter design and size on two or more documents. 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. And, the extent of pressure applied to the design area adds more depth to watermarks. Triton X-100: Added till surface tension in between 27 to 30 dyne. If applicable, this procedure is non-destructive, and rather non-detectable. In this case Mark was retained to perform a Questioned Document Examination (QDE). They are also called simulated watermarks (sometimes chemical watermarks too). Handwriting Comparisons 2. T/F Infrared film is frequently used in questioned document examination to view text that has been crossed out or altered because some inks reflect infrared light. When faced with a computer-generated document, the investigator first attempts to classify the printing process by identifying the printing technology.

In simulated writing, however, the pen may be lifted more frequently from the page, as it is easier to achieve an accurate shape and proportion with a shorter line. When these watermarks appear in the questioned documents, they can state origin, manufacturer, retailer, and possibly the manufacturing date. 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. Thermal Translucent Ink for Inkjet Printers. around for many decades, especially when people and courts have. Adobe Photoshop or similar software may be used to assess line orientation and spacing, which may be particularly useful in helping to identify anomalies or distortions in the text. UV light provides more detail and contrast to an injured area, including bite marks, than standard lighting techniques.
