  1. Print Types • 3 main types: • Loops • Whorls • Arches ACOS 2.2, 2.3

  2. Loops A class of fingerprints characterized by ridge lines that enter from one side of the pattern and curve around to exit from the same side of the pattern ACOS 2.2, 2.3

  3. Loops, continued.. Two major Loop Types Ulnar Loop- loop opens toward the little finger Radial Loop- loop opens toward the thumb ACOS 2.2, 2.3

  4. Loops, continued.. Four distinct loop types Plain- one ridge makes a complete circle Central pocket loop- if two deltas do not touch on the circle Double loop- two loops combined in one fingerprint Accidental- the catch all category, if the print does not fall into any other category ACOS 2.2, 2.3

  5. Whorls A class of fingerprints that include ridge patterns that are generally rounded or circular in shape and have two deltas ACOS 2.2, 2.3

  6. Arches A class of fingerprint that is characterized by ridge lines that enter the print from one side and flow out the other side ACOS 2.2, 2.3

  7. Arches, continued.. Plain arch- simplest of all prints, line enters on one side of print and exits the other side Tented arch- sharp spike in the center of the print ACOS 2.2, 2.3
