fingerprint

Back 7

Front 12

patent

Back 12

A fingerprint that happens when fingers with blood, ink, chalk, grease or dirt on them touch a surface and transfer the pattern of their fingerprint to that surface

Front 13

plastic

Back 29

This whorl pattern is made up of any two loops combined into one print

Front 30

accidental

Back 30

Whorl Fingerprint type consisting of a combination of two different types of patterns or which conforms to none of the normal fingerprint type definitions

Front 31

12

Back 31

To be absolutely certain two prints match, they must have this many common minutiae

Front 32

8

cyanoacrylate

Back 35

Super glue fingerprinting method

Front 36

ninhydrin

Back 36

This fingerprint test results in a purple-blue print when amino acids found in sweat react with this chemical

Front 37

silver nitrate

Back 37

Chloride from salt in sweat on a print combines with this to form dark colored prints

Front 38

iodine

Back 38

Fuming this chemical causes fingerprints to appear brown then quickly fade

Front 39

individual

Back 39

Fingerprints are this type of evidence
