Which term describes prints not visible without processing?

• A. Patent Prints
• B. Visible prints
• C. Impressed prints
• D. Latent prints

Answer: (D)

Latent prints are fingerprint impressions that aren’t visible to the naked eye. They’re formed from small amounts of sweat and oils left on a surface, which usually don’t produce color or contrast, so they can’t be seen without some kind of processing. To visualize them, investigators use methods like powders, chemical reagents, or fuming, and sometimes alternate light sources. By contrast, patent prints are already visible because they’re deposited with a colored material (like blood or ink), and impressed prints are physical indentations left in soft materials. Visible prints refer to any print you can see without processing. So the term for prints not visible without processing is latent prints.
