What type of fingerprint is characterized as visible to the naked eye?

The type of fingerprint that is characterized as visible to the naked eye is known as a patent fingerprint. Patent fingerprints are formed when a finger comes into contact with a surface that leaves a noticeable impression, often using substances such as ink, blood, or other liquids. This type of fingerprint does not require any enhancement or special lighting techniques to be seen, making it readily identifiable during investigation.

In contrast, latent fingerprints are not visible without the aid of powders or chemical techniques, as they are made up of oils and sweat left on a surface. Plastic fingerprints, which are three-dimensional impressions left in soft materials like wax or clay, can also be seen, but they are not typically referred to as visible in the way patent fingerprints are. Whorl refers to a specific pattern type of fingerprint but does not indicate its visibility. Understanding these distinctions is essential for anyone preparing for the Evidence Technician Exam, as it highlights the various categories of fingerprints and their characteristics.
