What does deposition distortion refer to in fingerprint analysis?

Deposition distortion in fingerprint analysis refers to the vertical weight on friction ridges. This type of distortion occurs when the pressure or weight applied to the surface during the deposition of a fingerprint changes the shape and characteristics of the ridges, which can affect the print's clarity and accuracy during analysis.

Understanding this concept is crucial for forensic professionals, as identifying the source of distortion allows for better interpretation of the latent prints. When a fingerprint is recorded, whether on a porous or non-porous surface, factors like body weight or the position of fingers can lead to variations in ridge patterns. Recognizing that deposition distortion is primarily associated with vertical pressures helps analysts account for anomalies that may arise during the fingerprinting process. Thus, accurate identification and interpretation of latent prints necessitate a deep understanding of how such physical forces can affect ridge structures.
