The primary premise of handwriting identification is that no two people write exactly alike, although natural variations occur within the handwriting of each individual. Questioned Documents was published in 1910, and a second edition in 1929. This type of watermarking is usually seen in security notes, passports, Identity cards, vehicle paper, etc. Watermark is a distinctive form of image, shape, text, or any design that appears translucent and fainter when light passes through it.

These three (fiber accumulation, defects, and logs) properties add additional identification markers to forensic document examinations. The quality (class and individual characteristics) of handwriting is governed by schooling .

Trained forensic document examiners systematically inspect questioned documents and compare aspects of the document to known standards in order to identify the nature and source of the writing or printing. The author, Albert S. Osborn, is called the Father of Questioned Documents. The Scientific Working Group for Forensic Document Examination (SWGFDE) is another organization that develops standards in the field of forensic document examination.

As a result, subtle details often relied upon in the analysis of handwriting or typed writing may not be reproduced. 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 . The examination of handwriting and signatures involves the comparison of writing on the document in question to additional samples in order to determine potential authorship. ESDA works by creating an electrostatic image of indented writing, which is then visualized by the application of charge sensitive toners.

Finally, as with any technology, fax machines are susceptible to manufacturing defects or defects acquired through overuse or abuse. Like chemical watermarks, they are also embedded after the production of paper. 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. Scientific Response and Analysis.

Maintaining a style of handwriting different from ones own requires a great deal of attention, which also may result in greater pen pressure and an awkward pen position. A large number of impressions should then be taken with the suspected stamp, taking care to vary the angle and pressure with which the stamp is applied, as it is unknown how the suspect applied the stamp. 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.
