What is Forensic Fingerprints?

Forensic fingerprints is the process of using fingerprints to prove that a particular person was present at a specific location or touched a specific object. This is usually done as a way to demonstrate guilt or innocence in criminal cases, although it has limited use outside this area. People have combs on the fingers that are generally unique to individuals. As a result of oil and sweat on the hands of man, people leave fingerprints of virtually everything they touch. Experienced forensic scientists can distinguish prints of one person from another and then compare the printing for existing records to prove identity.

When a person touches the surface, a small amount of material usually remains. This material will correspond to the ridges found on the hands and feet, because these are areas that most contact the surface. For a person who is qualified in fingerprints, this material is the key to the identity of the person who has abandoned it. Difficult part of the fact that even if the fingerprints of each č č areUnique lovka, most copies will vary every time they are made - also not unheard of for more people to have sections of ridges that are virtually identical to their fingers. The angle at which the print was created was touched by the surface and pressure on the pressure has huge effects on the structure and printing of the printing.

In order to beg with this person, the person will make forensic fingerprints compare key points between prints and look for common factors. When the printing is created, some sections will look the same as other prints, while some sections will not. Comparing the points on the finger suffering from the least distortion, and in areas that coincide across prints, it is possible for forensic fingerprints to determine probable match.

There are four main types of fingerprints. The exemplary printing is specifically considered to be a fingerprint recording. These are usually the best possible prints because of the removalThey are in a controlled environment using professional methods. Plastic prints are another preferred type of printing. These prints are perfectly preserved prints contained in three -dimensional form, such as the impression in the clay or plaster.

The most common prints used in forensic fingerprints are two that are not so well made. Patent printing is a fingerprint that is visible to the naked eye. These prints are often produced by touching a dirty or very clean reflective surface, such as a dusty car or mirror. Latent prints are invisible under normal conditions. These prints require them to become visible special powder or lighting conditions.
