Fingerprints have been developed on porous surfaces (papers, etc.) forty years and later after their deposition. On non-porous surfaces, they can also last a very long time. The nature of the matrix of the latent print will often determine whether it will survive environmental conditions.
Can fingerprints be left on paper?
Paper is particularly susceptible to fingerprints, as the paper fibers can absorb the oils and sweat from fingertips. Such “latent” prints can be left behind and found by investigators at the scene of a crime. Use caution, because rubbing too hard will cause the paper to become thin.
How long do fingerprints last on materials?

Can fingerprints be left on all surfaces?
Patent prints can be found on a wide variety of surfaces: smooth or rough, porous (such as paper, cloth or wood) or nonporous (such as metal, glass or plastic). Latent prints are formed when the body’s natural oils and sweat on the skin are deposited onto another surface.
Does hand sanitizer remove fingerprints?
Don’t use hand sanitizer! Hand sanitizer, though, has a lot of alcohol in it, which dries out your skin and makes it harder to capture print details. And, like with lotion, it can leave a filmy substance on your skin that messes up your print image.
Do gloves hide fingerprints?
Many criminals often wear gloves to avoid leaving fingerprints, which makes the crime investigation more difficult. Although the gloves act as a protective covering for the wearer’s prints, the gloves themselves can leave prints that are sometimes unique like human fingerprints, thus betraying the wearer.
What surfaces can fingerprints not be lifted from?
Non-porous smooth surfaces include varnished or painted surfaces, plastics, and glass. Non-porous rough surfaces include vinyl, leather, and other textured surfaces.
Can Heat destroy fingerprints?
Yes, exposure to excessive heat is detrimental to the fingerprint. As prints are primarily composed of water, much of any print left by your burglar may, in fact, have evaporated. Trouble is, there is no way of really knowing this without conducting the examination.
