Ink Dating—Comparative Examination of Inks on Documents using Optical and Chemical Methods
Abstract
Comparison of inks on the same or multiple documents is one of the ink dating approaches that determines and compares the physical and optical characteristics (including ink line morphology defects) and chemical composition of writing inks on documents. In this work, writing samples produced by 400 ballpoint pens (200 new and 200 used pens) were examined under the microscope, and the relative frequency of occurrence of various morphology defects, including certain reproducible ink line morphology defects that can be used for the purposes of relative ink dating, was determined. Also, the paper outlines typical case situations in which a comparative examination of inks on documents using optical and chemical methods is used for dating purposes.
