The dynamic approach is very useful in determining if a pen ink was placed on a document on its purported date, i. 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.
