Ink dating is one of the most trustworthy methods to assist in determining the age of a document. The chemical analysis of inks can assist in the following ways: Numerous inks can be chemically associated with other inks to confirm or disprove whether the entries were written contemporaneously.

Abstract. Two main approaches can be used for determining the age of an ink: indirect dating and direct dating. Indirect dating is based on the chemical analysis of an ink followed by comparison with known samples in a reference collection.

The age of documents may also be determined by examination of the paper, ink, toner and other attributes of the document. Some of these examinations require engaging specialists such as ink chemists, paper experts and others.

IPS Testing is able to determine likely age ranges for paper products by using wood fibers, pulping chemistry, paper additives and surface treatments to serve as dating markers. Our experienced fiber science team, led by Walter Rantanen, has developed an international reputation for paper and document forensics.

FORENSIC EXAMINATION OF PAPER It may be used to ascertain whether different pages of a document were printed or written on the same type of paper, or for document dating to determine whether a sheet of paper is as old as it was purported to be.

Examiners are frequently asked to determine the age of a document, particularly those that are handwritten in ink. A document may consist of a number of entries made at different times, and questions may arise as to whether a particular entry was made at a purported time.

The actual age of the document is ascertained by the study of all the means by which it was produced and the actual conditions under which the document was kept. The age of a document can be roughly estimated by using the following: 1. Content of the documents(phraseology, chronological significance, tense 2.

Inks contain chemical solvents that evaporate and generally go through a drying process that can last up to 2 years. We use the most widely accepted chemical analysis technique known as gas chromatography/mass spectrometry (GC/MS) to help determine if a written entry was created in the past two years.
