List the three major fingerprint patterns and their respective subclasses. Loops: ulnar, radial Arches: plain, tented Whorls: plain, central pocket loop, double loop, accidental Classify a set of fingerprints by the primary classification of the Henry system.
In forensic science, fingerprints are often regarded as one of the most reliable forms of evidence. Their uniqueness to each individual makes them a powerful tool in crime scene investigations. For aspiring forensic inve...
Pattern classification of fingerprints follows the NCIC Classification, an extension of the Henry system. The table below summarizes the possible classes and subclasses of fingerprint patterns, and when to mark special cases. In broad terms, patterns are divided into three types: arches, loops, and whorls.
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.
The fingerprint pattern, such as the print left when an inked finger is pressed onto paper, is that of the friction ridges on that particular finger. Friction ridge patterns are grouped into three distinct types—loops, whorls, and arches—each with unique variations, depending on the shape and relationship of the ridges: ...

Print patterns There are three basic fingerprint patterns: the arch, the loop, and the whorl. These patterns are defined by structures known as cores and deltas. The core of the print is the central area. A delta is a triangle-shaped area of a fingerprint where the ridge formation changes direction. Arches have one

There are three types of fingerprint patterns within what is known as the Henry Classification System, a method of differentiating fingerprint types that has endured for more than 100 years. Although every human fingerprint is unique, the Henry system breaks down the varieties into three types — the arch, the loop and the whorl.
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.

Apart from the three main fingerprint types, two more exist: Double Loop Whorl – With close observation, this pattern seems to contain two separate loops which surround each other from different directions.. Accidental –Any pattern which doesn’t match with other types listed here fall in this category. These patterns contain two features of the tented arch, loop or whorl patterns.
Ridge is defined as a black line that is made when an inked fingerprint is pressed against paper. Recurving ridge is one ridge that creates an inverted ‘U’ shape. Delta is defined when two parallel ridges diverge and go in opposite directions.This most resembles a triangle shape. The term delta is easy to remember, just think of a river that dumps out into the ocean or lake.
