Ink Age Determination

Ink Age Determination – Dating

Forensic Ink Dating

Sometimes the date of a written ink entry on its own or else relative to other entries on the same document is questioned.  Chemical tests can be conducted that may determine how long the ink has been on the document and whether a document entry has been falsely dated.  Documents bearing such entries may be single page documents or bound documents, such as journals, calendars or diaries. A destructive technique is used for this examination, i.e., small samples of the ink line are removed from the paper.

EXPECTED RESULTS

It is possible to determine that an entry on a questioned document was placed on that document at a time other than that indicated.

SUBMITTER’S RESPONSIBILITIES

All documents submitted should be properly inventoried and submitted to the lab.
