Several ink dating methods based on solvents analysis using gas chromatography/mass spectrometry (GC/MS) were proposed in the last decades.These methods follow the drying of solvents from ballpoint pen inks on paper and seem very promising.Nathan is always smiling and great fun to work with.There are four major approaches (each approach is a group of methods) used for dating inks on documents: 1.An extensive Monitor investigation has subsequently determined that the six papers detailed in the April 25 piece are, in fact, almost certainly forgeries.The Arabic text of the papers is inconsistent with known examples of Baghdad bureaucratic writing, and is replete with problematic language, says a leading US-based expert on Iraqi government documents.is a worldwide firm specializing in forensic document examinations (handwriting analysis), ink dating and document dating examinations, latent fingerprint examinations, firearms and toolmarks examinations, crime scene investigations, technical reviews of sexual assault kits, and forensic biology (DNA testing and consulting).We have worked with some of the largest law firms in the world with a mission to provide the highest quality forensic science services to both the governmental and private sectors.
On April 25, 2003, this newspaper ran a story about documents obtained in Iraq that alleged Saddam Hussein's regime had paid a British member of Parliament, George Galloway, million over 11 years to promote its interests in the West.
The SET and SLRM measure certain ink aging parameters of ink that decrease as ink ages on paper. To date, the SET is the only ink aging method that has shown its reliability through outside proficiency testing using “blind” samples (outside proficiency tests in 1995, 2001, and 2011). Ink Availability Approach The second ink dating approach analyzes the chemical composition of inks on a contested document with the aim to determine whether these inks (as well as other materials used to produce the document – paper, inkjet printing ink, toner, stamp pad ink, etc.) were commercially available on or prior to the date appearing on the document. – The examination’s purpose is to assess whether the entries being compared were produced with the ink of the same composition or with different inks (pens). The order of execution of certain elements of a document Writing ink sequencing – Examining intersections (areas where two or more pen lines cross) to determine the order of writing (it may prove that a particular entry was added at a later time) Sequencing of indented impressions and writings – Examining intersections (areas where the visible ink lines cross the indentations) may determine the order of writing and thus prove that a particular entry was added at a later time.
Other ink entries are not necessary for comparison. Aginsky has developed the SET as a result of many years of research of the ink aging methodology developed and published by Dr. For example, if the questioned document’s date precedes the manufacturing date for the ink used to sign the document, it is established that the document could not have been signed on the date it bears. Such intra-comparisons of inks may reveal that the questioned entries were not written contemporaneously with the other entries in the file (document). – The examination’s purpose is to assess whether the use of various inks on the document(s) fits a pattern that is either consistent with the dates appearing on the document(s) or indicates preparation "at one time" (during a short period of time). Paper folds – It is often possible to determine whether an ink line that intersects a paper fold was written before or after the paper was folded.
