Abstract
In document examination casework, the need for a method to differentiate pigmented black inkjet inks and determining their age increases. More and more documents are produced using the inkjet print technique. Commonly this raises questions for the examiner concerning the machines used to produce the documents and the age of the prints.
The first part of this preliminary study aims to distinguish different inkjet inks (printed on paper) by analyzing their main volatile components and assigning them according to their composition. In the second step of the research, it will be assessed whether it is possible to date these inks by measuring the decrease of volatile ink components (e.g. 2-Pyrrolidone, TEGBE) as a function of time.
