Manusgraphic method of identifying more accurately the handwriting of a particular person

摘要

The handwriting produced by a particular person can be identified more accurately if not only the trace of the lines typical of that person when producing the handwriting is detected but also the changing pressure which the hand exerts on the underlying surface during the course of producing the handwriting. This is performed by incorporating in the paper or some other material on which the handwriting is to be produced an emulsion which comprises differently sized and differently resistant sorts of spheres filled with different quantities of the same colour or with different colours and/or with differently magnetic material, which quickly burst in a planned way dependent on the pressure and consequently produce on the data carrier a coloured and/or electronically readable marking dependent on the respectively exerted pressure. These results can be teletransmitted and compared with documents optically and electronically.
