A new method that determines the age of a document in a less invasive way than other techniques and is also able to date documents up to five years old.

In fact, the dating of documents is a key area in the field of forensic science.

The problems 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.

To do this, they used BIC® ballpoint pens, one of the most common makes and, therefore, the most widely used in documents subjected to legal examination.

Materials such as charcoal, wood, peat, and textiles typically undergo the acid-alkali-acid (AAA) method before radiocarbon dating.
