|BASIC FINGERPRINT PATTERNS:
There are three main fingerprint patterns:
In a Loop pattern, the ridges will flow in one side, recurve, (loop
around) touch or pass through an imaginary line drawn from the
delta to the core, and exit the pattern on the same side as it entered.
*A loop pattern has only one delta.
*There are two types of loop patterns:
1. Ulnar loop
2. Radial loop
*Loop patterns account for @ 70% of all fingerprints
|2. WHORL PATTERNS:
A whorl pattern consists of a series of almost concentric circles.
* A whorl pattern has two deltas
*There are four types of whorl patterns:
1. Plain whorl,
2. Central Pocket Loop whorl,
3. Double Loop whorl,
4. Accidental whorl
*Whorl patterns account for @ 25% of fingerprints
In an arch pattern, ridges flow in one side and flow out the
opposite side. There are no deltas in an arch pattern.
*There are two types of arch patterns:
1. Plain arch,
2. Tented arch
Arch pattern account for @ 5% of all fingerprints
|CLASSIFICATION OF FINGERPRINTS
There are two generally accepted methods of classifying fingerprints:
1. Henry Classification
2. NCIC Classification
|FINGERPRINTS ARE PERMANENT AND INDIVIDUALLY UNIQUE
