Analyze Age Document For Free

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.

Though there are some indirect and expensive tests available for the identification of age of a paper, there is no well-defined technique to differentiate an artificially aged document from a naturally aged document, so far.

Testing a Paper's Age-Old Story Using Fiber Science 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.

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.

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.

The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BCE in China.

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.

Forensics Document Examiner Description The job of a forensic document examiner may involve identifying the author of a document, determining the source of a document and figuring out whether the document has been altered in any way since publication. They may also compare signatures to determine forgeries.

Most forensic document examiners analyze handwritten evidence. Signatures are the most common form of evidence that needs to be analyzed. Specifically, the court usually questions the authorship and authenticity of a signature or written letter. Other handwritten evidence includes wills, contracts, and deeds.

The examination's primary purpose is to provide evidence about suspicious or questioned documents using a variety of scientific principles and methods. Document examination might include alterations, obliterations, paper analysis, forgery, origin, determining authenticity, or any other questions.
