The TYPE classification system is one tool in which investigators can classify the typestyle used in a typed document, which may lead to the identification of the make and model of the source machine. A former FBI Special Agent who was also a Forensic Examiner within the FBIs Questioned Documents Unit spearheads our Questioned Document Examination (QDE) practice. 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. Imaging instruments such as Video Spectral Comparator (VSC) use radiations of varying wavelengths to disclose writing in a different ink. Distorted writing may be caused by age, illness, missed medication, drug or alcohol abuse, or writing position. The study is about questioned document and medico legal importance of documents, inks, printer and etc. Chemical tests are important in the examination of printing inks because they also allow examiners to provide an approximation of when the document was written. 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. Their concentration and composition determine the extent to which they can create opacity. c.

Localized Watermarks: Appears at a specific position of the page with definite intervals. The relatively poor quality of faxes and photocopies, in comparison to the original document, means that they may be particularly susceptible to manipulations or alterations for fraudulent purposes. It is sometimes possible to remove the obliterating material using an ordinary rubber eraser, chemical solvent or scraping off the overlying layer, although pains must be taken not to damage the underlying writing. 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.
