Fingerprinting is the activity of collecting fingerprint impressions of a person to use in different applications. Originally, this was attained by rolling the palm and fingers in ink and transferring them on fingerprint cards. Better technology in the current era has allowed the use of computer scanners which scan the impressions and store them on computer memory. To have a good understanding of in fingerprinting Dallas is a recommendable place to pay a visit.

Fingerprints from individuals can be performed through several methods. Major methods and types can be classified as patent, plastic, electronic recording, exemplar, and latent. When the prints are collected deliberately with the full consent of the subjects, they are referred to as exemplar prints. Some of the circumstances under which this can happen include during employment in certain companies, during arrest, and when enrolling into a program. Arrested individuals need to have their fingerprints collected to be used for official records. Live scans or ink and paper cards are some of the ways collection is done.

In forensic science Latent prints refer to the kind of prints left behind by accident or chance. It does not matter whether at the instance of deposition they were visible or not. Such deposition may result from natural sweat on hands or from contaminants like paint, ink, motor oil, or blood among others. Application of physical, electronic, and chemical processing techniques permit visualization of unseen print residues.

Latent prints may not be complete hence may only reveal a section of the desired patterns. Sometimes they are distorted, smudged, or overlapped with other fingerprints. They are therefore not a reliable source of comparison due to lack of clarity, content, and undistorted information like those taken under controlled situations. However the pattern type such as whorl, loop, and arch may be clearly visible.

Plastic and patent prints have some resemblance because they both involve leaving impressions in foreign substances that are able to retain the patterns on the hands. Wet clay and flour are some of major examples of such substances. The need to use processing techniques to derive prints is eliminated because they are normally visible and sufficiently clear. Photographs are always sufficient. Electronic recording becomes handy in determining matches from photographs.

Identification also called dactyloscopy is the major reason for fingerprinting. Dactyloscopy relies on the idea that no two individuals have prints that are exact in all aspects. Infact, impressions of the same person recorded almost at the same time may feature some slight differences. Experts who are involved in this exercise follow strict rules before declaring any two prints as similar or from one individual.

Skin pliability, surface material, roughness of surfaces, slippage, and deposition pressure are some of the factors that affect fingerprinting. These factors cause adverse effects on how friction ridge deposition occurs. This is the reason behind the extensive and intensive training that professionals who examine prints undergo. Fingerprints are scientifically studied under a field called dermatoglyphics.

The legitimacy of evidence based on prints has always been received with a lot of criticism. Law, media, and academics are the major fields that have challenged soundness of this technique. In spite of low error rates, criticism has made this field controversial.
