Exposed :: Lifting the Prints

When lifting fingerprints, different approaches are taken for different types of fingerprints. For these two specific lifting techniques, I will list the steps needed to be taken to lift latent fingerprints off of different surfaces.

Solid Dark Colored Surface:

STEP 1: Find a good print.

STEP 2: Use a white powder, such as talc, and gently cover the entire fingerprint with it.

STEP 3: Lightly blow off the excess powder. There should now be a visible print.

STEP 4: Using a clear piece of tape, cover the entire area to transfer the print off of the surface.

STEP 5: In this case, you can place the strip of tape onto a black sheet of paper. The print should now be easily visible and ready for the identification process.

Solid Light Colored Surfaces (Including Glass):

STEP 1: Find a good print.

STEP 2: Use a dark powder, such as graphite, and gently cover the entire fingerprint with it.

STEP 3: Lightly blow off the excess powder. There should now be a visible print.

STEP 4: Using a clear piece of tape, cover the entire area to transfer the print off of the surface.

STEP 5: In this case, you can place the strip of tape onto a white sheet of paper. The print should now be easily visible and ready for the identification process.
