The DOUBLE LOOP is made up of any two loops combined into one fingerprint. Any print classified as ACCIDENTAL either contains two or more patterns (not including the plain arch) or the pattern is not covered by other categories i.e., a combination loop and a plain whorl or a loop and tented arch. Examples of these are more clearly shown below:
Analysts use the general pattern type (loop, whorl or arch) to make initial comparisons and include or exclude a known fingerprint from further analysis. To match a print, the analyst uses the minutiae, or ridge characteristics, to identify specific points on a suspect fingerprint with the same information in a known fingerprint.
Everyone's fingerprints are unique. However, specific patterns can be seen in fingerprints. The three main types of fingerprints are separated into multiple categories within each category. Also Read: What is Fingerprint? Three Types of Fingerprint Patterns Are: Arch Loop Whorl Henry's system is based on four distinct groups of patterns: Arch Loop Whorl Composite Types
Illustrations 1 to 10 are examples of the various types of fingerprint patterns. [Figs. 1-10] Interpretation. ... It may be a combination of loop and tented arch, loop and whorl, loop and central pocket loop, double loop and central pocket loop, or other such combinations. The plain arch is excluded as it is rather the absence of pattern than a ...
Compare your fingerprint to the examples below to see if you have a loop, whorl, or arch. Loop. The loop is the most common type of fingerprint. The ridges form elongated loops. Some people have double loop fingerprints, where the ridges make a curvy S shape. Whorl. In a whorl fingerprint, the ridges form a circular pattern. ...
A plain whorl will have one core without any direction if the pattern is circular and two cores with direction if the pattern is elliptical. Whorl – Central Pocket Loop – A type of fingerprint pattern which at least one recurving ridge or an obstruction at a right angle to the line of flow.

The three fundamental fingerprint types are loops, whorls, and arches. Loops are the most common, accounting for about 60% of all fingerprints. Whorls are the second most common, making up 30-35% of fingerprints. Arches are the rarest, occurring in only about 5% of fingerprints.
valleys in fingerprints form a limited number of overall patterns Ð loop, whorl, or arch (see diagram 3 on page 3.02Ð3). In 1894, detectives at LondonÕ s Scotland Y ard began using fingerprints to identify criminals by comparing the pattern of a suspectÕ s fingerprint shapes with those of known criminals. In the first part of

These are: loops, whorls, and arches. Approximately 60% of the total population has loops, 35% have whorls, and 5% have arches. The three major groups are also subcategorized based upon smaller differences existing between the patterns within the specific group. These subcategories are as follows: I. ARCH II. LOOP III. WHORL

Whorl 1. A plain or central pocket whorl has at least one ridge that makes a complete circuit. 2. A double loop is made of two loops. An accidental is a pattern not covered by other categories. 3. Whorls have at least two deltas and a core. 4. Types •Plain •Central pocket •Double loop •Accidental
CLASSIFICATION OF FINGERPRINTS. 1. The sorting of fingerprints into file groups so that a file may be set upon on. the basis of fingerprints alone. Fingerprints are classified by general. shape, (arch, loop, or whorl) position within the finger, and relative size. 2. Classification of fingerprints provides for an orderly placing of fingerprint
The three types of fingersprints are arch, loop and whorl. Within each type of fingerprint there are different types of arches, loops, whorls. The type of fingerprint on the left is a loop. The top right fingerprint is a whorl. The bottom right fingerprint is a arch. Arches. Arches can be subdivided into two categories: tented arch and plain ...
Loops are ridge patterns that recurve back on themselves, while whorls are circular or spiral patterns. The uniqueness of each individual's fingerprint lies in the specific combination of these ridge patterns, their direction, and the presence of minutiae points such as ridge endings and bifurcations.
Whorl fingerprints are one of the three main types of fingerprints, along with loops and arches. They are characterized by circular or spiral patterns and make up approximately 30% of all fingerprints. Within the category of whorl fingerprints, there are three distinct subgroups: plain whorls, central pocket loop whorls, and accidental whorls.
