worrointinob ♥♥♥ Link: How accurate is forensic ink dating The aim of this work was to study the drying process of ballpoint ink, characterised by the disappearance of volatile solvents from the ink entry. For real cases samples, more parameters have to be studied and other possible pathways have to be considered. Quantities of ethoxyethoxyethanol, dipropylene glycol, phenoxyethanol and phenoxyethoxyethanol were studied in ink entries up to 1. ScienceDirect ® is a registered trademark of Elsevier The low quantities of solvents in the microgram range for a 1 cm ballpoint entry were found to decrease quickly after deposition of the ink on paper through the competitive processes of evaporation and diffusion. Copyright © 2017 Elsevier Losses of up to 75% of solvents were observed after a few seconds. It was observed that ethoxyethanol, dipropylene glycol and phenoxyethanol can also migrate from one sheet of paper to another if placed close enough e. The amount of ethoxyethanol stopped decreasing after about 10 days quantities reached the nanogram range for a 1 cm ballpoint entrywhile the aging curves of dipropylene glycol, phenoxyethanol and phenoxyethoxyethanol level off considerably after 2 weeks. Phenoxyethanol is of particularly high interest as it is found in more than 80% of the blue ballpoint pens at different concentrations. Please enable JavaScript to use all the features on this page. Therefore, it is important to understand the aging process of the different components found in ink. The determination of how accurate is forensic ink dating age of an ink entry from a questioned document is often an essential problem and a controversial issue in forensic sciences.
