One of the downsides of this however is that client expectations on what is possible in certain areas of forensic science often greatly exceed what can actually be done. Usually the enquiry involves a signature on a will or a commercial document. The signature itself may not be in dispute but the actual date of signing may be critical to the resolution of the matter. Often the client believes that the document can be easily analysed to give an exact date the ink was placed on the paper.
This testing has the disadvantage that the original document must be released to a laboratory, something that is problematic for many legal documents and potentially expensive for the client.

There’s more to a piece of paper than meets the eye – and paper analysis can find it. This specialized investigative process extracts historical and physical evidence from documents, photographs, art prints, books, and other paper-based objects. These tools are used, alone or in combination, to characterize the properties of paper in a number of ways. For example, a qualitative analysis shows what materials are in the paper, fiber, ink; quantitative analysis measures how much.
Chemical analysis evaluates composition and pH; physical analysis measures gloss, strength, color. Organic analysis detects carbon-based traces of plants and organisms; while inorganic analysis identifies mineral evidence in pigment and ink. Each of these approaches provides a set of facts about an artifact’s condition, age or origins. The method of choice for any given situation is determined by several factors, including: the objectives of the investigator authentication, preservation, personal curiosity ; the relative value of the paper historically, legally, personally ; and whether the information gained from destructive testing will outweigh the loss of material samples.
