Plastic fingerprints are impressions made in what type of surface?

Explanation:
Plastic fingerprints are three-dimensional impressions that form when a finger is pressed into a soft, malleable surface such as clay, wax, putty, or soap, leaving a full relief of the ridge patterns. The key idea is that the print is embedded in a material that deforms around the ridges, creating a mold of the fingerprint rather than a smear on a hard surface. This is different from latent prints, which are invisible and require development on a surface, or patent/visible prints, which are already visible without any processing. So the impression is made in a soft substrate, producing a plastic (three-dimensional) fingerprint.
