You may be asking yourself, “What is a patent print, anyway?” Simply put, it's a fingerprint that's visible to the naked eye. But hold on, there's more!

Now, let’s explore this a bit deeper. Patent prints are unique because they don’t require any additional enhancement to see them.

You can think of latent prints as shy actors waiting in the wings, and patent prints taking center stage, fully illuminated!

Now, you may wonder why some options suggested otherwise. For instance, fingerprints typically originate from a person’s skin, which leads many to think that the source of the print matters.

It's the charm of the foreign substance that gives it life and makes it easily recognizable.

Imagine a greasy fingerprint left on a doorknob—it tells a story all its own! If you find such a print, there’s a good chance you’re looking at a patent print. The medium—be it dirt, ink, or something else—is vital for this type of print to even exist.
