This includes the security of information, computers and networks, cryptography, cyber-physical system security, digital forensics, and other related fields. This also includes digital forensic research, case studies, investigation models, investigation tools analysis, electronic evidences, reporting and future of digital forensics. In addition, the journal publishes papers that take an interdisciplinary approach to the study of cyber and information security, including topics such as international relation, data protection, privacy, ethics, legal issues, and economic implications.</p> <p>Editor-in-chief:<br />Dr. Pratosh Bansal (Professor, Department of Information Technology, Institute of Engineering &amp; Technology, Devi Ahilya Vishwavidyalaya, India)</p> <p>Managing Editor:<br />Dr. Tina Porwal (Managing Editor, Granthaalayah Publications and Printers, 109/C, Sukhdev Nagar Ex2, Airport Road, Indore, 452005, India)</p> https://www.digitalsecurityforensics.org/digisecforensics/article/view/48 2025-07-01T06:24:55+00:00 Piyush Thakur connect.piyushthakur@gmail.com Navjot Kaur Kanwal kanwalnk@gmail.com Shilpa Nair silpanair87@gmail.com Parveen Kumar Janjua drpkjanjua@gmail.com

<p>The present study aims to identify and analyze the individualizing characteristics of documents printed using various inkjet printers through non-destructive examination with a Video Spectral Comparator (VSC-40). Printed samples were collected from twelve different inkjet printer models, primarily from the EPSON, HP, Canon, and Brother brands. Standardized A4 paper was used to ensure uniformity in analysis. Under VSC-40 magnification, several distinguishing features such as edge sharpness, dot roundedness, blooming effect, extraneous dots (satellite drops and overspray), directional artefacts, line defects, and banding patterns were systematically examined. The study observed that EPSON printers, utilizing piezoelectric technology, demonstrated superior edge sharpness and minimal blooming effects compared to other brands. Printers like Brother-DCP J140w exhibited pronounced blooming and banding defects. Features such as directional tailing and consistent line defects proved useful for determining the type of printing technology employed and for linking documents to their sources. The findings confirm that VSC-40 imaging provides a reliable, non-destructive means for the forensic differentiation of inkjet-printed documents, enhancing authenticity verification and source identification processes in questioned document examination.</p>
