Bobby, Regarding prints on paper being affected by contact with plastic; I don't know of any studies in that regard. Further, I would add that if you are referring to a plastic bag containing the paper, then understand that environmental changes can affect conditions within the bag regarding moisture, which could adversely affect the latent print residue. In other words, the environment could even affect the evidence if it is sealed in a plastic container. -Kasey | ||

Excellent answer, Kasey. Thanks! You guys are awesome. I suppose it also depends on how many people come in contact with it as well! Can constant contact with plastic remove fingerprints on paper? Just wondering... | ||

Bobby, It really depends on the finish. Different manufacturers of wood paneling put different finishes on their products, so to generalize would be misleading. Picture a quality table-top with dark stain and a hand-rubbed finish, almost as smooth as glass. It would best be classified as a non-porous surface. On the other hand, if you have a piece of pine shelving with a coat of stain, it is almost as porous as regular wood, and would best be classified as a porous surface. And of course, there is an entire range in between. No definite answer on this one! -Kasey | ||

Sorry to bother you again, Kasey, and thanks for your prompt replies, but I keep getting intrigued by further questions! Is treated wood, such as wooden paneling or sealed wood, considered porous or non-porous? Thanks! |
