Forensic Identification of Suspected Document on the Basis of their Ink Profiling

Abstract

The forensic suspected/questioned document is a very challenging ground. Hardly a day energy by deprived of some document playing a portion in the life of human lives. Questioned documents are verified consistently in forensic science laboratories for their genuineness. Human development has observed script organizations mean while early period also for footage determinations or as a means of communication. The script resources and tools used in the earlier comprised stone, wax, vellum, quills, leaf, wooden materials, etc. [1]. In questioned document cases, one of the current significant features contains the proof of identity and judgement of indicator (permanent and whiteboard) pen inks which are extensively used for numerous requests. These inks are finished up of colorants (i.e., dye or pigment), a solvent or thinners, resins, surfactants, lubricants, emulsifiers, and additives [2]. The most significant query for file specialists is to response whether the liquid ink used is similar or dissimilar in the manufacture of a document. Consequently, the present method delivers valued vision to the forensic expert production with questioned document inspections. It also helps in the connection of unidentified pointer inks to the enduring or whiteboard markers which can thin down the statistics of alleged samples [3].
