Rolling Technique
In order to take advantage of the natural movement of the forearm, the hand should be rotated from the more difficult position to the easiest position. This requires that the thumbs be rolled toward and the fingers away from the center of the individual's body. This process relieves strain and leaves the fingers relaxed when rolling so that they may be lifted easily without danger of slipping which smudges and blurs the fingerprints.

Roll each finger from nail to nail in the appropriate space taking care to lift each finger up and away after rolling, to avoid smudging.
