What is the significance of the term 'latent' in context to latent prints?

The term 'latent' in the context of latent prints is significant because it refers to hidden impressions that are not immediately visible to the naked eye. Latent prints are formed when the natural oils and sweat from a person's skin are transferred to a surface, creating an impression that can remain undetected until it is developed using specific techniques. This hidden nature makes latent prints an important area of study in forensic science, as they can be critical evidence in criminal investigations. Techniques such as dusting with powder, fuming with chemicals, or using alternative light sources are often employed to reveal these latent impressions. Understanding this term is crucial for law enforcement and forensic professionals in the process of identifying and collecting evidence.
