Film for pharmaceutical use, compression tool for the production of tablets, tablet press, method for producing microesturutas on superfu00eccie a tool.A tablet (4) for pharmaceutical use is in at least a part of its surface a microstructure difrativa (11) that generates diffraction effects which may be discerniveis in the range of the visible spectrum and which serves as a visual characteristic of security.The tablet (4) consists of a plurality of individual particles of dust, and the difrativas microstructures (11) are on the surface of the particles embossadas individual post.A compression tool (1, 1a, 1b, 3) to produce such tablets (4) has microstructures (11) at a surface pressure of the compression tool (1, 1 A, 1b, 3), and such microstructures (11) have dimensions which are smaller than the dimensions of the individual cristalitos (3 0) of the material of the surface of the pressure of the compression tool (1, 1 A, 1 B, 3).The microstructures (11) of the compression tool can be produced e.g. by ion erosion or embossamento.
