   Visible prints are formed when blood, dirt, ink, paint, etc., is transferred from a finger or thumb to a surface. Patent prints can be found on a wide variety of surfaces: smooth or rough, porous (such as paper, cloth or wood) or nonporous (such as metal, glass or plastic).

   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.

   What is a fingerprint examination?

   • Fingerprint examination involves looking at the quality and quantity of information in order to find agreement or disagreement between the unknown print (from the crime scene) and known prints on file. To conduct the examination, fingerprint examiners use a small magnifier called a loupe to view minute details (minutiae) of a print.

   What is a fingerprint identification?

   • A fingerprint identification is the process of determining that the same finger made two or more fingerprint impressions based on the friction ridge details of both impressions. When a fingerprint lift is made, the latent print examiner must conduct a comparison, where appropriate, in hopes of completing an identification.

   Where can fingerprints be found?

   • Fingerprints can also be found on rougher surfaces such as wood, tightly woven materials, starched fabrics, and human skin. In addition, any loose paper or documents should be thoroughly checked for latent prints. If possible, objects that are suspected of having prints on their surfaces should be collected.

   A latent print is an impression of the friction skin of the fingers or palms of the hands that has been transferred to another surface. The permanent and unique arrangement of the features of this skin allows for the identification of an individual to a latent print.
