What is the definition of latent fingerprints?

Latent fingerprints refer to prints that are not immediately visible to the naked eye and require a specific development process to be visualized. These prints are typically formed when oils and sweat from fingers transfer onto surfaces, creating an impression that can be enhanced through various forensic techniques, such as powder dusting or chemical treatments. The ability to make these latent prints visible is crucial in forensic investigations, as they often serve as valuable evidence linking a suspect to a crime scene.

The other choices do not describe latent fingerprints correctly. Visible fingerprints are those that can be seen without enhancement, while prints left on impact surfaces may include both latent and visible prints but do not exclusively refer to the invisible nature of latent fingerprints. Additionally, the notion that latent prints are always clear and distinct is inaccurate, as their quality can vary significantly based on the conditions of the surface and the medium of deposition.
