DETECTION AND IDENTIFICATION OF PRINTER INKS - A REVIEW REPORT ON LASER AND INKJET PRINTER INK ANALYSIS

The increased rate of crime involving the use of laser and inkjet printed documents is the motivation of writing this paper and to produce efficient analytical techniques for classification, identification, detection and analysis of laser and inkjet printed documents. A printed document is usually examined to determine whether or not it is forged or to determine its source of origin etc. The examination can be carried out either physically and chemically. The main aspiration of this paper is to collect and provide every useful and relevant information so that they can be implemented in a questioned document laboratory. This review paper indicates how the analysis of the printer inks can be used for the establishment of origin of a printed document.
