Understanding Fingerprint Types

Fingerprint Classification Fingerprints are basically of 4 types : 1. Loop – 45-48% 2. Arch – 7-8% 3. Whorl – 45% 4. Accidental – 1%

Sub-Type of Loop Sub-Type of Arch a. Ulnar Loop b. Radial Loop a. Simple Arch b. Tented Arch c. Tented Arch with Ulnar Loop d. Tented Arch with Radial Loop

Sub-Type of Whorl 1. Target Centric Whorl 2. Spiral Whorl 3. Elongated Whorl – Target Centric 4. Elongated Whorl - Spiral 5. Double Loop Whorl 6. Composite Whorl 7. Imploding Whorl 8. Ulnar Peacock’s Eye 9. Radial Peacock’s Eye

Flow Delta Finger Print Type - ARCH with RADIAL LOOP Finger Print Code to be updated – X2 Flow Delta 1. This print will look like a Loop, with a DELTA & FLOW 2. But, the Ridge Count (no. of lines between Delta & Center) will be less than 9 3. Right hand’s print & Flow is in Left side – Radial Loop Right Hand’s Print

ARCH with ULNAR & RADIAL 1. Left Hand’s Print & Flow is also in Left Left - Left (Matching) = Ulnar Loop Arch 2. Right Hand’s Print & Flow is also in Right Right - Right (Matching) = Ulnar Loop Arch Left – Right (Not Matching) = Radial Loop Arch 3. Left Hand’s Print & Flow is in Right 4. Right Hand’s Print & Flow is in Left Right - Left (Not Matching) = Radial Loop Arch

Centre Delta Delta Finger Print Type - TARGET CENTRIC WHROL Finger Print Code to be updated – W1 1. Circular lines, round & round shape with 2 Delta Centre 2. Target centric whorl will have 2 Delta, 1 on left & 1 on right Delta 3. Centre - It has an independent center, like a dot, a small line or a circle, like a “Dart Game” 4. Ridges move around the centre of the print in a circular manner Delta

Centre Delta Delta Finger Print Type - SPIRAL WHROL Finger Print Code to be updated – W2 1. Delta is like “Y” shape, ridge (lines) come from 1 direction and at 1 point they are split. Centre Delta 2. Centre - It has a connected center, attached with next ridge 3. Ridges start from centre of the print in a circular manner 4. Spiral whorl will have 2 Delta & 1 centre Delta

Centre Delta Delta Finger Print Type - ELONGATED WHORL (TARGET/ SPIRAL) Finger Print Code to be updated – W1 OR W2 1. Delta is like “Y” shape, ridge (lines) come from 1 direction and at 1 point they are split. Centre 2. Elongated Whorl is a stretched form of Target Centric or Spiral Whorl 3. Ridges are around the centre in a stretched form. Delta 4. It can be spiral or target centric having 2 Delta & 1 Centre 5. If Center is target centric code to be W1 and if Center is of Spiral Type as in example image code to be W2 Delta

Centres Delta Delta Finger Print Type - DOUBLE LOOP (S Family) Finger Print Code to be updated – W3 Centres 1. Its name is Double Loop but it’s not Loop, it’s Whorl. It’s called double loop because it’s formed by combination of 2 loops. 2. Centre- This whorl has 2 centre points Delta 3. Ridges start from both centre & move in opposite direction. 4. It has 2 Delta Delta 5. It is “S” shape in center. DOUBLE LOOP WHORL

Centres Delta Delta Finger Print Type - IMPLODING WHORL(S Family) Finger Print Code to be updated – W3 Centres 1. Delta is like “Y” shape, ridge (lines) come from 1 direction and at 1 point they are split. 2. Centre- This whorl has 2 centre points Delta 3. Ridges start from both centre & move in opposite direction. 4. It has 2 Delta , & 2 Centre 5. It is “S” shape in center, pressed towards the center Delta

Centres Delta Delta Finger Print Type - COMPOSITE WHORL (S Family) Finger Print Code to be updated – W3 Centres 1. Delta is like “Y” shape, ridge (lines) come from 1 direction and at 1 point they are split. 2. Centre- This whorl has 2 centre points Delta 3. Ridges start from both centre & move in opposite direction. 4. It has 2 Delta , & 2 Centre 5. It is “S” shape in center but small in size Delta

Centre Delta Finger Print Type - PEACOCK EYE – Type 1 Finger Print Code to be updated – W4 Centre 1. 1 Delta will be at its place & Second delta will be close to center 2. It will form a peacock’s feather shape from center. 3. If its Left hand’s print & Flow towards Left print type is Ulnar Peacock’s eye. 4. If its Right hand’s print & Flow is on Left side Radial Peacock’s eye, code remains same W4 in any of scenario. Delta

Centre Delta Finger Print Type - PEACOCK EYE – Type 2 Finger Print Code to be updated – W4 Centre 1. 1 Delta will be at its place & Second delta will be close to center 2. It will form a peacock’s feather shape from center. 3. If its Left hand’s print & Flow towards Right print type is Radial Peacock’s eye. 4. If its Right hand’s print & Flow is on Right side Radial Peacock’s eye, code remains same W4 in any of scenario. Delta

Centre Delta Finger Print Type - Accidental Finger Print Code to be updated – Of Type which is more dominant They have 2 or more deltas and a combination or fusion of 2 or more types of patterns not including the plain, radial or Ulnar arch. This category also includes any freak pattern or accidental formation that does not conform to any conventional type. Centre In given example we can observe more dominance of Tented Arch formation with Radial Loop formation, so we would have a Delta and Center marked along with code as X2 Delta

Coding System for preparing report Ulnar Loop L Radial Loop R Simple Arch X1 X2 Tented Arch/Tented Arch with Ulnar / Radial Loop W1 Target Centric Whorl/Elongated Target Centric Whorl Spiral Whorl/ Elongated Spiral Whorl W2 W3 S-Family i.e. Double Loop/Composite Whorl/Imploding Whorl W4 Ulnar/Radial Peacock’s Eye Accidental Code to be assigned depending upon the most dominant print type
