Mechanical impressions are impressions placed on a piece of paper by a machine or simple tool (e.g., typewriters, check writers, rubber stamps and seals).
It is often possible to identify the impression left on a document as produced by one particular machine or tool.
A print is the result of an impression. This is what distinguishes it from a drawing, a manuscript, and a painting. It is also the reason for which it can be reproduced in many examples.
The printing of a print is done using a printing element, of which there are various kinds, these various kinds are classed according to the way in which the ink is placed on their surface, in fact, it is essential to differentiate, in one way or another, the areas that will receive ink from those that will not.
