In forensic science, the accurate dating of documents, including newspapers, plays a crucial role in criminal investigations, particularly in cases involving the authenticity and timing of events. This study focuses on the aging processes of inks used in newspapers, a topic of significant interest due to its potential forensic applications. Despite the availability of simpler methods to determine publication dates, these methods often fall short when dealing with fragmentary evidence or when high precision is required. This research proposes a novel approach to dating newspaper fragments through the analysis of ink aging using Infrared Spectroscopy. The spectra were analyzed to identify changes in the chemical composition of the ink over time, with particular attention to the presence and intensity of functional group peaks. The findings indicate that the proposed method can provide a scientific basis for dating newspaper fragments with greater precision than traditional methods.
