Document Authenticity

Document authenticity

We can examine a document to determine its authenticity from three different aspects: historical, scientific, and stylistic.

Historical Analysis

In order to place the document in a specific timeline, we check the method of printing and the materials and techniques used. These must be consistent with place and time. Documents created on a typewriter or printed via inkjet or laser printer, fax machine, or photocopier may be attributed to a particular make or model, or even to a specific machine. The printing process used to prepare documents can also be identified.

Scientific Analysis

Detailed paper and ink analysis can establish the age of document. We are able to determine likely age-ranges for paper products by using wood fibers, pulping chemistry, paper additives, and surface treatments as dating markers. We also offer carbon dating for paper. Liquid chromatography can be conducted to identify the chemical composition of ink on a document. In this technique, a small cutting from the document in question is dissolved in a solvent and analyzed.

Stylistic Analysis

Style comparison is essential for authentication. Penmanship, cultural phrasing, and form of address can help identify both the era and author. Handwriting comparisons can authenticate a signature or manuscript.
