When analysing the kinetics involved in its disappearance, the research group established a pattern that links the state of the ink with the time that has elapsed.
More accurate, less invasive After observing this natural evolution and once the base guideline had been established, the next challenge to be overcome was to check the viability of the method using spontaneously written documents whose exact age was known, such as diaries, laboratory logs and judicial evidence from judicial processes that had been closed.
So Datink offers a more accurate, less damaging, less intrusive and less harmful result. The excavation work has demonstrated that the settlement, which is now home to the small Kurdish ...
Its use could have for example helped to determine the moment when the papers in the Bárcenas [corruption claims] case were written." To conduct the research work, the Department of Analytical Chemistry had the collaboration of the company Investigaciones Forenses Documentales LEYAS and Magdalena Ezcurra holder of a Ph D from the UPV/EHU.
This company also supplied the knowledge about the current problems in dating documents, real cases that had been subjected to legal examination.
Nevertheless, this methodology is a pilot experience that requires further in-depth research when it comes to evaluating the limits of the applicability of the various inks and makes of ballpoint pens, thus reducing its potential limitations. Historical research using forensic fingerprinting techniques on the wax seals of thousands of medieval documents will reveal new insights into 12th to 14th century British society, help determine how ...
As Luis Bartolomé pointed out, "what is interesting about this method is that it can more accurately determine the age of the stroke produced by the ballpoint pen.
