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. Many hands are made up of a mixture of characteristics from different styles.
Two main approaches can be used for determining the age of an ink: indirect dating and direct dating. Indirect dating is based on the chemical analysis of an ink followed by comparison with known samples in a reference collection. The collection should contain information about the inks including the market introduction dates.

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.

Most enquires regarding signature and handwriting comparisons typically fall into these two categories:. This is not asking who wrote it but instead, was it all written by only one person? The methodology of a signature or handwriting comparison depends on the following factors which influence what documents are required to endeavour to form a definite conclusion:. It is also normally essential to compare handwriting to handwriting and NOT handwriting to a signature as many writers will depart from the normal letter designs of their handwriting to write their signatures.
A sufficient quantity of specimen is required for a reasonably conclusive result.
In the later medieval and early modern periods in Scotland, clerks sometimes employed a way of writing dates which look distinctly odd to the modern reader.
Included in the discipline is the practice of deciphering, reading, and dating historical manuscripts,  and the cultural context of writing, including the methods with which writing and books were produced, and the history of scriptoria. The discipline is one of the auxiliary sciences of history. It is important for understanding, authenticating, and dating ancient texts. However, it generally cannot be used to pinpoint dates with high precision.
Palaeography can be an essential skill for historians and philologists , as it tackles two main difficulties. First, since the style of a single alphabet in each given language has evolved constantly, it is necessary to know how to decipher its individual characters as they existed in various eras. Second, scribes often used many abbreviations , usually so as to write more quickly and sometimes to save space, so the specialist-palaeographer must know how to interpret them.
Knowledge of individual letter-forms , ligatures , punctuation , and abbreviations enables the palaeographer to read and understand the text. The palaeographer must know, first, the language of the text that is, one must become expert in the relevant earlier forms of these languages ; and second, the historical usages of various styles of handwriting, common writing customs, and scribal or notarial abbreviations.
Philological knowledge of the language, vocabulary, and grammar generally used at a given time or place can help palaeographers identify ancient or more recent forgeries versus authentic documents.

Wills, endorsements on checks, letters, credit card applications or sales invoices, bank documents and even scribbled notations are just a few of the types of documents in which the identification of the author of the writing thereon may prove to be of value. On many occasions it is possible for the document examiner to state with no reservations that a particular individual did or did not write a specific written entry.
On other occasions, because of the limited or general nature of the questioned writing, the lack of a sufficient amount of known specimen writing, disguise in the questioned or known writing, or other reasons, it may not be possible to state the results with complete certitude but a qualified opinion may be expressed.
Depending on the weight of other evidence in the case, these qualified opinions may still be of value in subsequent decisions or prosecutions. The following is offered as the types of opinions that may be expressed by document examiners in handwriting cases, which for the purpose of this discussion, include handprinting cases:. Identification definite conclusion of identity : this is the highest degree of confidence expressed by document examiners in handwriting comparisons.
The examiner has no reservations whatsoever, and he is certain, based on the evidence contained in the handwriting, that the known writer actually wrote the writing in question. The evidence is very persuasive, yet some critical feature or quality is missing so that identification is not warranted; however, the examiner is virtually certain that the same individual wrote the questioned and known writings.
The evidence contained in the handwriting points rather strongly toward the questioned and known writings having been written by the same individual; however, it falls short of the virtually certain degree of confidence. Some handwriting may have few features, which are of significance for handwriting comparison purposes, but those features are in agreement with other writing, suggesting that the same individual may have prepared them.
Note: This is a very weak opinion and some examiners doubt the desirability of reporting an opinion this vague, but those examiners who are trying to encompass the entire gray scale of degrees of confidence may wish to use this or a similar term. Usually a statement that the evidence is far from conclusive follows this opinion.

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.
The most important thing is to determine the age of material paper, canvas, wood containing the handwriting and to date the ink or other pigment used. There are several methods of material dating, which are described under Scientific Tests on our web page. Very often the age of pigment or ink used is not the same as the age of the material on which the inscription was written.

There are only a handful of forensic scientists capable of performing these tests and laboratories equipped with the proper tools. The proposed tests are minimally invasive, the latter two involving the placement of pinhole perforations in the text, paper and signatures on the Original Document. The pinholes themselves are not typically easily visible unless the document is held up to light, and the testing has no negative effect on handwriting analysis.
All of the proposed testing follows Court approved testing methods, e. Under appropriate circumstances, the Court may order destructive testing of all or some portion of the physical item in question. Douglas E. Barnhart, Inc.
