The raster elements in documents and securities are designed with vector graphics. Images, the bases for the illustration, derive from pixel graphics. In our laboratory a method has been developed to carry out a transformation from pixelisation to linear graphics. Graphics of this kind are simultaneously complete protection and a depiction of the image primarily memorised in the computer via pictorial elements. The solutions provided make possible parametric control of the density and blackness of the leading direction of the lineature. The results of this research have been applied in the creation of securities. In additional research, the results achieved with iris printing are given.
