Latent prints are invisible to the naked eye, whereas "patent prints" or "plastic prints" are viewable with the unaided eye. Latent prints are often fragmentary and require the use of chemical methods, powder, or alternative light sources in order to be made clear.
Latent prints are formed when the body’s natural oils and sweat on the skin are deposited onto another surface. Latent prints can be found on a variety of surfaces; however, they are not readily visible and detection often requires the use of fingerprint powders, chemical reagents or alternate light sources.

25 de abr. de 2011 · Background. Latent prints (“latents”) are friction ridge impressions (fingerprints, palmprints, or footprints) left unintentionally on items such as those found at crime scenes ( SI Appendix, Glossary ).
Latent print examiners and processors use state-of-the art forensic technology to detect, develop and identify latent fingerprints, palm prints and footprints. A latent print is an invisible chance reproduction of a fingerprint that may be left behind by direct contact.
