Types of Fingerprints

Direct Prints: prints deliberatively given either for collection or when under arrest for a suspected criminal offense. These prints usually are collected by rolling each finger to get all the fingerprints.


Direct Fingerprint
Latent Prints: prints left behind from accidental contact with a surface. Latent prints usually only contain parts of the whole fingerprint and are sometimes smudged, distorted, or imperfect in other ways. These prints are less accurate for identification due to their lack of the fingers ridge and groove patterns.

Latent Fingerprint
Plastic Prints: are prints that create an imprint in a surface. These are usually found in melted candle wax, putties, thick grease, etc.


Plastic Fingerprint
Patent Prints: prints left that are visible to the human eye due usually to the transfer of materials on the fingers surface such as flour, clay, etc.

  3. Good job researching the different prints and how to tell them apart! You did an especially good job explaining what the latent print was. Just beware that you have a couple oddities in there where it says "Direct Fingerprint" and then underneath it'll explain what a latent print is. That confused me a bit :)
