Someone trying to sell a baseball allegedly signed by Babe Ruth in the early s, or pass off documents as older than they really are, is up against a serious foe: The United States Secret Service.

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.

In forensic science , questioned document examination QDE is the examination of documents potentially disputed in a court of law. Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods. Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court.

Many QD examinations involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship. A document examiner is often asked to determine if a questioned item originated from the same source as the known item s , then present their opinion on the matter in court as an expert witness.

Other common tasks include determining what has happened to a document, determining when a document was produced, or deciphering information on the document that has been obscured, obliterated, or erased. The discipline is known by many names including ‘forensic document examination’, ‘document examination’, ‘ diplomatics ‘, ‘handwriting examination’, or sometimes ‘handwriting analysis’, although the latter term is not often used as it may be confused with graphology.

In such cases, the former term refers to examiners who focus on non-handwriting examination types while the latter refers to those trained exclusively to do handwriting examinations.
