INK AGE DETERMINATION

Sometimes the date of a written ink entry relative to other entries on the same document is questioned.  Documents bearing such entries may be single page documents or bound documents, such as journals, calendars or diaries.  Before conducting this type of examination, two requirements must be met: 1) There must be entries on the document or similar documents whose dates are not questioned that are the same ink formula as the questioned entry, and 2) The questioned and unquestioned ink entries must occur on the same document or documents stored under the same conditions to ensure that the entries were exposed to the same environmental conditions.  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.
