Raster elements in securities typography
Sažetak
By using Postscript (*1) and the mathematical program Mathematica, various new raster forms (*2) have been created in the past few years. A line drawing as shown in Picture 1 is the conventional typography rastering in respect to securities. Programming with new rasters allows individualization in such a way that each document has its solution. Such raster forms represent extensive additional protection of the printed matter against counterfeiting. When images are reproduced various types of raster combinations are used. The positioning of raster elements may be generated by a sequence of pseudo-random numbers and in this manner counterfeiting is impossible. This paper shows the results of using various raster forms in typography. Typographic solutions have been created that use individualized raster in a new way, and they me used as a form of protection against counterfeiting.
