Abstract: The present study focuses on the forensic evaluation of ink removal using vinegar and ethanol on contract bond paper under varying temperature conditions. The study aims to investigate the effects of these chemical agents on ink visibility, paper characteristics, and the detectability of potential alterations in written documents. Vinegar, containing acetic acid, and ethanol are examined as treatment agents to determine their effects on ink markings and the physical integrity of contract bond paper at different temperatures. The evaluation considers observable changes such as ink fading, residual ink traces, paper discolouration, surface texture, and fibre damage. Untreated paper samples serve as controls for comparison. Forensic examination methods, including visual inspection and microscopic analysis, may be used to identify characteristics associated with chemical treatment. The study also considers temperature as a factor that may influence the interaction between the treatment agents, ink, and paper substrate. The findings are expected to contribute to the understanding of document alteration and the limitations of detecting chemically treated ink entries in questioned documents. This research may provide useful insights for forensic document examiners in assessing the authenticity and integrity of contract documents. The conclusions will be based on the experimental results obtained.
