The answer to that question may determine whether the document has been altered (by adding certain information).

Ink Aging Approach Various methods have been published to measure aging processes that occur in ink on documents. Aginsky is the author of two ink aging methods that analyze ink volatile components (not ink dye components*) and that have been tested and applied to actual cases by multiple forensic laboratories.This is generally modelled in laboratory and based on the evidence you can trace the date fairly accurately as to when the document was written.However the constituents present in other types of pens like ball pens are different in the sense that they dont disperse on the paper so easily and naturally.Questioned material may consist of identification cards, contracts, wills, titles and deeds, seals, stamps, bank checks, handwritten correspondence, machine-generated documents (such as those from photocopiers, fax machines, and printers), currency and electronic documents.In some circumstances, graffiti and digital signatures may be examined; however, the client should be aware that the examination of these types of evidence can be problematic.In this case what is done is that they analyse the extent to which the chemicals present in refill of ball pen has interacted with the external environment to get some idea when it was written.In printed documents however, long exposure to external enviroment has a very minimal effect on the quality of the typing, thus making it practically impossible to accurately mention its date of typing.When the writing on the reverse side of a sheet of paper in a bound ledger intersects with the writing on the front side of the sheet of paper, ink may be transferred from the front page onto an underlying page.Such transfers will occur only when inks are freshly applied.In addition, writing instruments, rubber stamps, envelopes and makes/models of office equipment in the suspect’s possession may be collected by the investigator.In digital documents, evidence could even be culled from the metadata of electronic signature files, providing information such as who the author is and when the document was written.
