But this technique is also able to overcome other stumbling blocks relating to the amount of ink deposited when writing and the type of paper used, as these variables hamper the dating of a document by means of traditional methods.What is more, the new technique reduces the number of punctures needed to analyse the writing on a document to just one.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.

During the natural ageing process of each sample, which had a known age, the research team analysed the evolution in the various volatile components.Until now, the passing of time was detected only in a very general way, in other words, it was possible to determine whether the document was young (whether it was less than 90 days old) or old (more than 2 years).So Datink has overcome some of the drawbacks graphology examination comes up against when ascertaining the age of a document by means of other methods.That is why it is very useful for documents that have been signed as it is possible to compare whether the body of the document, if it has been written by hand, is as old as the signature. Or else it is a very useful tool to date contracts, settlements, wills or other documents.
