An examiner of latent fingerprints explains the steps that should be taken to assure high quality record palmprints and major case fingerprints.
Abstract
The declining quality of record palmprints indicates that many law enforcement personnel need guidance on how to obtain high quality prints. The most important element in recording prints is a clean, dry hand. It is also important to put the proper amount of ink on the ink pad; the appropriate amount of ink is learned through experience. A firm, even pressure on the ink roller will deposit ink evenly over the entire palm. The correct touch for inking and printing can be acquired only with experience through frequent practice. The subject's hand must remain relaxed throughout the process. Care should be taken to record the side of the palm as well as the palmprint. The person taking the prints must also sign and date each sheet of record prints. Major case prints differ from palmprints in that they record all of the friction ridges of the hands. For major case prints, each finger must be rolled side to side and base to tip. A complete palmprint must be obtained as well. The person should roll the finger until the inked surface of the finger can be seen. A light touch should be used, since too much pressure will force the ridges together. Taking complete, quality record prints will avoid the need to take extra time to relocate and reprint the subject. Photographs are provided.
