The Loop



In fingerprints, as well as in the usual application of the word

loop, there cannot be a loop unless there is a recurve or turning

back on itself of one or more of the ridges. Other conditions have to

be considered, however. A pattern must possess several requisites

before it may be properly classified as a loop. This type of pattern

is the most numerous of all and constitutes about 65 percent of all

prints.



A loop is that type of fingerprint pattern in which one or more of

the ridges enter on either side of the impression, recurve, touch or

pass an imaginary line drawn from the delta to the core, and terminate

or tend to terminate on or toward the same side of the impression from

whence such ridge or ridges entered.
