Plain whorl fingerprint6/6/2023 ![]() Whorls - form circular or spiral patterns, like tiny whirlpools. Divided into radial loops (pointing toward the radius bone, or thumb) and ulnar loops (pointing toward the ulna bone, or pinky), loops account for approximately 60 percent of pattern types. Loops - prints that recurve back on themselves to form a loop shape. 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: 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. ![]() Prints from palms, toes and feet are also unique however, these are used less often for identification, so this guide focuses on prints from the fingers and thumbs. You now have your Primary Classification.Fingerprints are unique patterns, made by friction ridges (raised) and furrows (recessed), which appear on the pads of the fingers and thumbs. Again for the denominator, assign numerical values on blocks 1, 3 and 5, sum it up and it'll be 28, add 1, becomes 29 and thats your denominator. First, assign numerical values in blocks 2 and 4, sum it up and it'll be 24, add 1, it will become 25. How did it happened? Simple, get a sheet of paper and follow me. The primary classification would be 25/29. All right fingers are whorl, and left fingers are loops. And all fingers in odd blocks are "denominator". All fingers in even blocks are "numerators". However, you must take note of the "Numerator" and Denominator". After assigning the values, count the total. And to make it happen, assign numerical values in fingers having Whorls. Those are the fingerprint pattern without numerical value in the Primary Classification.ġ & 2 (right thumb & right index), both with numerical value of 16.ģ & 4 ( right middle and right ring), both with numerical value of 8.ĥ & 6 ( right little and left thumb), both with numerical value of 4.ħ & 8 (left index and left middle), both with numerical value of 2.ĩ & 10 (left ring and left little ), both with numerical value of 1.įor Primary division, it is always in numerical value. Patterns without numerical value – The arches and the Loops. Patterns with numerical value – All Whorls- these are the patterns (fingerprints) assigned with numerical value in the Primary Classification.
