This work presents a comparative forensic analysis of handwriting characteristics in Hindi scripts written on various surfaces, with the objective of enhancing the precision and reliability of forensic document examination. The study explores the impact of different substrates, including paper, fabric, plastic, and glass, on distinctive handwriting features such as stroke formation, slant, pressure, and spacing. Through a combination of microscopic analysis, digital imaging techniques, and statistical assessment, the research investigates how the physical properties of these surfaces—such as texture, porosity, and reflectivity—affect the manifestation of handwriting characteristics. The results provide crucial insights for forensic experts, emphasizing the need to consider surface-dependent variations when analysing handwriting in diverse contexts. The findings contribute to the advancement of forensic document examination methodologies, offering a deeper understanding of the challenges associated with non-traditional writing surfaces and their implications for forensic investigations.
