Review on handwriting examination on unusual surface

Abstract

Individuals have a unique handwriting style, which can aid investigators in identifying suspects and perpetrators at a crime scene. A handwriting analysis can also provide information about the crime's circumstances, including its social and physical surroundings. Handwriting investigations use a variety of analytical factors, including pen pressure, line quality, alignment, and the spacing between words and letters, to determine the mode, conditions, and surroundings of the crime. However, the use of atypical surfaces at crime scenes for handwriting evidence may pose a problem to detectives as they may affect the normal handwriting of the victim, requiring more complex analytical instruments and lengthy investigations. This paper analyzes the success rate of forensic investigations and conclusions linked to handwriting analysis, including the impact of various writing implements on non-traditional and unique surfaces.
