Reproduction - a Latin word. It is translated as "reproduction". In other words, a reproduction any process of obtaining copies of any given objects in any given form can be called. The industry of the equipment carrying the name of a reprography is engaged in a reproduction of two-dimensional images. Inventors of different eras developed a set of types of reprographic processes. They use the most various physical and chemical processes. There is a black-and-white and color reprography. The reproduction even of very expensive picture costs much cheaper than the original and if this picture turned into public property, for creation of such reproduction it is not necessary even to carry out any payments.
Reproduction of the population or reproduction, process of maintenance of number of inhabitants in any given area invariable or increasing due to compensation of mortality birth rate is called.

The devices capable to keep a sound in time, that is to carry out reproduction in legal sense of this word, are known from the second half of the nineteenth century. They similar to the equipment for a reprography use the most various physical principles.
