Fingerprinting Steps • Encourage the individual to relax. Ask them to look at a distant object to distract them. • Grasp the individual's right hand at the base of the thumb with your right hand. Cup your hand over the their fingers, tucking under those fingers not being printed. Guide the finger being printed with your left hand. www.fbi.gov
Fingerprinting Steps • Roll the finger on the pad so that the entire fingerprint pattern area is evenly covered with ink. The ink should cover from one edge of the nail to the other and from the crease of the first joint to the tip of the finger. www.fbi.gov
Fingerprinting Steps • To take rolled impressions the side of the bulb of the finger is placed upon the card and the finger is rolled to the other side until it faces the opposite direction. www.fbi.gov
Fingerprinting Steps • 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 body. • Roll each finger from nail to nail taking care to lift each finger up, to avoid smudging. www.fbi.gov
Fingerprinting Steps • Plain impressions are printed last, at the bottom of the card. Press the individual's four fingers (on the right hand), keeping the fingers together, on the surface of the fingerprint card at a forty-five degree angle. • Print both thumbs simultaneously in the plain impression thumb blocks. www.fbi.gov
