چکیده
Abstract Printer inks are becoming necessary for utilization wide range of purposes by society in current times with rapid development technology and digital media area. Thus, forgery counterfeiting easier the criminals. It is dangerous as some criminals will misused mean addition adulteration parts text or numbers on document can be made an evidence trial court. characterization differentiation printed suspected documents (civil criminal cases) may provide important information about authenticity printer inks. The focus this study to differentiate chemical component three different types sample incorporation FTIR spectrophotometer principal analysis. unique features ink samples were unmasked from score plots graphical representation provided spectra analysis enabled discrimination certain

Chromatographic Analysis of Inks for Forensic Science Applications.
This article reviews the use of chromatography for the separation and comparison of ink components. Thin layer chromatography (TLC) is the standard chromatographic procedure presently employed for the comparison of inks. Thin layer chromatography systems are described for the separation of different types of ink. The greater sensitivity and resolution offered by high performance liquid chromato...
متن کاملEffect of electron beam irradiation on forensic evidence. 2. Analysis of writing inks on porous surfaces.
The effect of electron beam irradiation on a series of different writing inks is described. As the anthrax-tainted letters were discovered in October 2001, the U.S. government began to experiment with the use of the electron beam irradiation process for destroying such biological agents. Plans initially considered a large-scale countrywide use of this technology. However, over time the scope of...
متن کاملForensic discrimination of blue ballpoint pen inks based on thin layer chromatography and image analysis.
This article aims to provide a new and fast method for differentiation of inks on a questioned document. The data acquisition was carried out by designing specific image analysis software for evaluating thin layer chromatograms (TLC-IA). The ink spot was extracted from the document using methanol and separated by TLC using plastic sheet silica gel 60 without fluorescent indicator, and a mixture...
متن کاملForensic analysis of ballpoint pen inks using paper spray mass spectrometry.
A novel analytical approach based on paper spray mass spectrometry (PS-MS) is developed for a fast and effective forensic analysis of inks in documents. Ink writings made in ordinary paper with blue ballpoint pens were directly analyzed under ambient conditions without any prior sample preparation. Firstly, the method was explored on a set of distinct pens and the results obtained in the positi...
متن کاملPrinter identification based on graylevel co-occurrence features for security and forensic applications
In today’s digital world securing different forms of content is very important in terms of protecting copyright and verifying authenticity. Many techniques have been developed to protect audio, video, digital documents, images, and programs (executable code). One example is watermarking of digital audio and images. We believe that a similar type of protection for printed documents is very impor...
