What is a latent printing press?

Latent printing is an analyst of the scene of the crime scene that examines items for fingerprints and compares all fingerprints found against the central database. Latent fingerprints that are impressed by different combs in the skin that are coated with sweat are often not visible to the mere eye. The fingerprints of each person are unique without exception and look the same from 16 weeks of pregnancy until death if there is no serious injury.

One of the main tasks of the testing latent print is the use of techniques identification of chemical and physical fingerprints. Another part of the task is to analyze fingerprints. Testing fingerprints are trying to find many different characteristics that each fingerprint has. Since there are more than 100 unique fingerprint identifiers, partial printing can also be considered as evidence of fingerprints. Latent prints can be easily blurred, shaken or affected by some events, which is a necessity for an examiner of latent printingEye and thorough understanding of methods and technologies used in this field of criminology.

Latent fingerprints can be visible in many ways. Dusting with pigment, using chemicals such as ninhydron or cyanoacrylate pairs and inking are valid methods that can be used by latent press testing. The fingerprint visualization method depends on a number of factors, including, but not only on the composition and sensitivity of the surface on which the prints are turned on, the climate and the size of the object that is examined on the fingerprints.

Once these fingerprints are identified and analyzed, the criminologist may begin to compare the fingerprints found with a database of prints or prints taken from a person suspected of committing a crime. The fingerprints of the suspect involves pressing the fingers by ink and converting into paper in a controlled scientific way. Hence the latent printing examiner can scan fingerprints underDeveloped to the computer and compare them with prints found at the scene of the crime, thereby eliminating or confirming the suspect.

qualifications for the state differ to the latent press examiner according to the place and place of employment. For example, in the United States, it is generally accepted that in order to become a latent press investigator, a person must achieve certification through the International Association of identification (IAI), which also has associated entities in more than a dozen other countries. Although different places have different job requirements, IAI certification is accepted almost everywhere.
