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.
It should be noted that sequence of execution may be determined even when lines of the text and signature (handwritten notation) do not intersect. * At present, the ink aging methods that analyze ink dye components are considered unreliable by the overwhelming majority of ink dating specialists and forensic document examiners.Southworth has received numerous calls asking if we can determine when a particular sheet of our paper was made. Dawson wrote the following article explaining first hand how important a date-coded watermark can be.On approximately half of the calls we receive, we identify that the paper was made after the document states it was written. One of the questions a forensic document examiner is asked to solve many times is the age or common origin of two or more sheets of paper.Watermarks frequently establish the authenticity or spuriousness of the questioned document(s), the genuineness of which may depend on the date of the watermark or more importantly the date mark on the watermark.The following case history demonstrates how a date mark on a watermark alone can expose a fraudulent document. in Spartanburg, South Carolina alleging that “page 3″ of a Will was fraudulent and was not prepared at the same times page 1, 2, and 4 (the signature page) was executed. An attorney’s secretary testified she had prepared the Will, witnessed each page and personally witnessed the decedent sign page 3 and 4 at the same time.
