What are latent prints?

Latent prints refer to fingerprints that are not immediately visible to the naked eye. They are typically left behind on surfaces when the natural oils and sweat from the skin come into contact with an object, creating an impression that cannot be seen without assistance. These prints require enhancement techniques, such as dusting with powder or using various chemical processes, to make them visible for analysis and comparison.

This concept is crucial in forensic science, as latent prints play a significant role in criminal investigations to identify suspects. The ability to develop these prints from various surfaces enhances the effectiveness of fingerprint analysis in solving crimes.

Visible fingerprints, as mentioned in the other options, are readily seen without any enhancement, and thus do not fall under the category of latent prints. Fingerprints left on paper may be considered latent prints in some contexts, but the defining characteristic of latent prints is that they are often invisible until enhanced. Similarly, fingerprints made under duress relate to the conditions under which they are created, rather than their visibility or the need for enhancement.
