Useful to know

Initially, the reproduction unit was a device used to make photocopies of texts, drawings, diagrams, tables, paintings, pictures, photographs and other similar, mainly flat objects.

Law enforcement activities are impossible without registering and replicating information, without copying and reproducing documents. In the 70-80s of the 20th century, obtaining copies of documents, as well as various texts and various images on a plane was carried out using a reproduction unit.

The reproduction unit was widely used in forensic practice in the production of handwriting, fingerprinting, portrait examinations, as well as in forensic technical examination of documents. Thus, when studying the impressions of seals and stamps, typewritten and handwritten texts, it was possible to form a visual representation of the individual characteristics of the impressions, the letters of the typewriters used, the handwriting of the person who wrote the text. This helped to identify etched, washed off, filled in or crossed out entries in documents, to establish the fact of changes in their content. In operational investigative activities, it was used, in particular, to reproduce photographs when searching for and identifying criminals, and to obtain copies of documents.

Photographing the general appearance of a document helped to display its most important features. The photograph showed: the document itself, including the margins and all details of the text (marks, impressions of seals and stamps, signatures, etc.), as well as existing damage (tears, charring, fold lines, etc.).

Photographic reproduction is usually carried out in two ways: on a reproduction unit and by contact. In the first case, photography is done with the original illuminated by two-sided uniform light falling at an angle of 25-30°. The document should be parallel to the plane of the film, and the optical axis of the lens should be directed to its center. Photographic reproductions are made from originals on a transparent base by contact with transmitted light. Reproductions are obtained from opaque documents by the so-called reflex method, in reflected light. The original to be copied is placed on a hard, flat base, and reflex photographic paper is placed on it, emulsion layer down. Then the paper is pressed tightly against the original with glass and illuminated through the backing. After development, a negative is obtained, from which positive photocopies are printed in a similar way.

Currently, computer copying methods using copying and duplicating equipment are used to obtain a significant number of copies of a document, however, these copies of the document do not always reflect the entire volume of information and the available material traces of the crime. In addition, with the growth of expert light sources, reproduction units have expanded their potential. A reproduction stand equipped with spectral light sources allows for the detection of many invisible traces with a high probability, and slit light sources allow for handwriting examination.
