What are the 3 types of prints?

• B. Visible, Olfactory, Tactile.
• C. Dust, Ink, Footprint.
• D. Digital, Numeric, Color.

Answer: (A)

In fingerprint work, there are three main categories of prints: latent, patent, and plastic. Latent prints are hidden or not readily visible; they’re formed by oils and sweat left on a surface and usually require special techniques (like powdering or chemical development) to be seen. Patent prints are visible to the naked eye because they’re left in substances such as blood, ink, or mud, making the print already apparent without processing. Plastic prints are impressions made in soft materials—like wax, soap, or clay—where the print is actually molded into the surface and three-dimensional. The other options mix terms that aren’t categories of prints themselves (olfactory and tactile relate to senses, not print types) or refer to techniques or unrelated concepts (dust, ink, and footprint, or digital, numeric, color), which isn’t what the question is asking.
