Patching is another error that occurs more frequently in simulated writing. Promote self-regulation, documentation, training, continuing education, and research (ibid). . Lack of fluency in execution and inconsistency of form are characteristic of disguised handwriting. Forensic examiners are often required to evaluate the authenticity of an individuals signature, particularly in the case of contested wills or other legal documents. They are created when a pattern, text, or image is printed with opaque, transparent, white, or using varnish-based ink. 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. White balance Transmitted faxes are often printed at a relatively low resolution, compared to documents that are printed or photocopied.

And, the extent of pressure applied to the design area adds more depth to watermarks. Watermarks also may be useful to examiners as a means of identifying the type of paper, manufacturer, and date of production. Alterations 5. 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.

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. Tools and Methods Document examiners of the 21st century use microscopy, chemistry, laboratory instrumentation and digital photography to uncover important clues. 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. More clearer and detailing is seen in cylinder moulding watermarks. Topics discussed include training and qualifications for forensic document examiners as well as the various methods used to exam differing projects, such as signatures, checks, computer and type generated documents, as well as obliterated writing.

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. Watermarks are frequently visualized simply by using transmitted light or soft x-rays, which produces an image of the density of fibers. Like chemical watermarks, they are also embedded after the production of paper. b. extremely dark or extremely bright. Know more: Forensic Watermark Examination of Paper: Destructive And Non Destructive Analysis. Liquid chromatography may be conducted in order to determine the chemical composition of inks used in a document. 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. Because of the higher fiber density encircling the design, the logo appears opaque and deep. Another way to trace writing is to place carbon paper on top of the original document so that the pressure of the pen will produce a carbon impression upon the lower document.

Quick history: They were first used in 1848. More probably, the examiner will be able to trace the ink back to the specific type, class, and or brand of ink, and suggest that it is scientifically indistinguishable from the suspected source. Artificial watermarks are widely used to authenticate and identify secure documents such as banknotes. These defects may occur in the source machine, the recipient machine, or both, and must be differentiated from the noise that may occur during transmission.

Qde reviewer. 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. As a result, subtle details often relied upon in the analysis of handwriting or typed writing may not be reproduced. Finally, paper fiber analysis is a destructive technique that allows examiners to identify the type and quantity of fibers involved as a result of the pulping process. c. detailed notes can be spoken much faster than they can be written.
