one loop exiting from left side and one from right side. The pattern is made by either overlapping or surrounding one another and both the loops after terminating exiting from the both sides of the delta. Loops slant toward the right of the fingerprint card Right slant in right hand: Ulnar loop (backslash, ).

TWIN LOOP: This is often also a double loop pattern. Right-Slant Loops Also called Right Loops.

This is often basically a double loop pattern in which two loops are formed either by overlapping or surrounding one another and both the loops after terminating exiting from the same side of the delta.

In this pattern majority of the ridges forming a loop but at the center one or more ridges within the pattern are forming an whorl or pocket like structure.

CENTRAL POCKET LOOP: the central pocket loop is a combination of a loop and a whorl.

COMPOSITE: the composites are combinations of all the above mentioned patterns. Compare your fingerprint to the examples below to see if you have a loop, whorl, or arch. You can use a magnifying glass to get a better look. Examine the ridges of your fingerprint, which has expanded on the balloon. Download scientific diagram Common five fingerprint classes: (a) left loop, (b) right loop, (c) whorl fingerprint contains two loops and two deltas, (d) plain arch fingerprint does. Lift your finger off without smudging the ink. It has at least one ridge forming complete trip may be in the form of spiral, oval, circle. Press your finger, flatly and firmly, on the deflated balloon. Plain whorl posses a type line and at least two deltas.

WHORL: Almost 30-35 % populations have whorl pattern.

Ulnar loop: The loop where the ridges start from ulnar loop or little finger of the hand and recurving around the core and exiting to the same side of the hand.Radial loop: The loop where the ridges start from radial bone or thumb side of the hand and recurving around the core and exiting to the same side of the hand.60-65 % of population have loop pattern.īased on the side where the ridge recurve they are of two types: LOOP: A loop is formed when one or more ridges entering from the same side recurving, existing form the same side.Ī loop always has a core and a delta. Tented arch(T): In this ridges entering from left side making an upright thrust at the center flowing towards the right side of the pattern.The ridges run from left side to other side with a small rise at the center like a hill or hump. Plain arch (A):This is the simple of all fingerprint patterns.The pattern accounts for approximately 5% of recorded fingerprint. ARCH: the ridges run from one side of the print to another side forming an arch like formation. There are 4 major types of fingerprint patterns

Right loop fingerprint
