What is a latent print?

Explanation:
A latent print is a fingerprint that isn’t visible to the naked eye. Latent means hidden; these prints come from sweat and oils left on a surface and require processing—like powders or chemical developers—to become visible. This invisibility is what makes latent prints central to many investigations: once you apply the right method, the print can be visualized and collected for comparison. In contrast, an obvious fingerprint can be seen without any treatment, which isn’t latent. A DNA sample is a different type of evidence, and a footwear impression is a shoe print, not a fingerprint.
