Abstract :
Handwritten evidence plays a crucial role in forensic investigations, especially in cases where documents are produced under unusual conditions. This study investigates the impact of unusual writing instruments, such as lipstick and kajal-stick, and unconventional surfaces, such as mirrors and tissue paper, on handwriting characteristics. A comparative analysis was conducted on writing samples obtained from 30 individuals under both normal and unusual conditions. The study highlights variations in line quality, slant, spacing, connections, and letter forms, while also noting features that remain consistent across conditions. The findings emphasize that while unusual conditions can distort handwriting, subconscious habitual features can still aid forensic document examiners in authorship determination.
