Which type of fingerprint is created as a 3-D impression?

A plastic print is considered the correct answer because it refers to a three-dimensional impression made when a finger presses into a soft material, such as wax, clay, or the surface of a putty-like substance. This results in a detailed and recognizable impression of the ridges and patterns of the fingerprint, capturing the unique features that can be used for identification.

Latent prints are not three-dimensional; they are invisible or faint prints left on surfaces due to sweat or oils from the skin and require special techniques to be visualized. Patent prints, similarly, are visible fingerprints that have been deposited onto a surface with colored substances like ink or blood. These prints are typically two-dimensional rather than three-dimensional impressions. Consequently, while all types of prints have their significance in forensics, plastic prints uniquely demonstrate the aspect of being a 3-D impression.
