What are the main subsets of imprints?

The main subsets of imprints refer to the different ways in which impressions can be categorized based on their origin and characteristics. The correct classification consists of visible, latent, and plastic imprints.

Visible imprints are those that are easily seen with the naked eye, such as footprints left in mud or blood. Latent imprints are not immediately visible and require various techniques or methods to be developed for them to be seen. This could involve using powders or chemicals to reveal them on surfaces. Plastic imprints are three-dimensional impressions left in a soft material, like a footprint in sand or a fingerprint in wax.

In the context of forensic evidence, understanding these categories allows technicians to effectively document, preserve, and analyze various types of imprints encountered at a crime scene. Each type of imprint requires different methods of collection and preservation, which is crucial for maintaining the integrity of evidence for potential legal proceedings.
