Dating of Documents
The scripts favoured by English scribes evolved and changed over time. At the beginning of the medieval period, scribes used ‘set’ scripts, which were very formal and tidy. Well-separated letters were their principal characteristic. However, the most significant development in script in the English Middle Ages was the evolution of cursive hands which made the process of writing quicker and more efficient.
Cursive scripts contain letter forms made with as few strokes of the pen as possible. They were first developed for the speedy copying of official documents or records, but gradually became used for copying other types of text.
Efforts have been made by scholars to determine the dates of the scrolls using human assessment of writing style and pragmatic considerations on provenance.

There are typically two different forensic methods for ink dating. With this method the forensic analysis determines the components in the ink, compares them against a library of standards and then allows an opinion regarding the first date that particular ink was manufactured commercially available. The dynamic approach is very useful in determining if a pen ink was placed on a document on its purported date, i.

The chemical analysis of writing and printing inks, as well as paper, can be invaluable when trying to prove whether a document is fraudulent. Ink dating is a highly specialized forensic examination and considered to be one of the most accurate and reliable methods to help determine the age of a document. An ink formulation can be identified to a specific manufacturer to ascertain the first date of commercial availability.
If an entry is dated in , but the ink was not available until then the document could not have been created in Inks contain chemical solvents that evaporate and generally go through a drying process that can last up to 2 years. Comparing Writing Inks. Chemical analysis can be conducted on a suspicious entry to determine if it is consistent with other associated or surrounding writings. Multiple inks can be chemically compared with each other to corroborate or refute whether the entries were created contemporaneously or produced over multiple periods of time.
Forensic Analysis of Printers and Copiers. Ink analysis and dating can also be conducted on machine printed document such as inkjet ink and toner from photocopiers, laser printers, and facsimile machines. Forensic Paper Examination.
Determining the age of a piece of writing document or inscription helps put it into historical context. Inscription dating for paintings or drawings is one of the main methods used in the authentication process. If we know when the inscription or signature was written on the painting, we can acknowledge its authorship.
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. Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used.
Until now, document dating methods have been able to indicate whether the writing was relatively new less than 90 days or older over two years , yet this chronological accuracy is insufficient in certain cases, above all in judicial ones. Each document was produced at different moments using a different ink stroke pressure, factors that may alter the results and lead to dating errors.
During the natural ageing process of each sample, which had a known age, the research team analysed the evolution in the various volatile components. 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. 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 the team used the same procedure as that used to analyse the samples produced for the research. And Datink also passed the test. In other words, when applying this analysis procedure, the team can indicate whether the document was written 1, days previously just over four years with a margin of days either way.
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. Likewise, the team that has developed this new method has managed to obtain results using minimal amounts taken from the document.
