This dissertation widens the range and opens a new approach to creating typography in security graphics. During several years of research it has been noticed that this subject has not been yet elaborated or presented through the stochastic approach. There was a need to introduce one's own program solutions carried out within the Post Script language on mutational typography. Fonts that were created by using digital tools are presented here as well as their use in security typography. Mutation of new fonts is being designed in securities and documents. The mutations are carried out by having texts go through programs created in advance. The paper presents gradation of the letter cut shade brightness carried out in micro typography. Besides offering security properties, micro typography also offers individual design solutions. New screening elements are introduced, the use of which is made possible with the development of digital printing. The stochastic approach and creating of random number generators have made it possible to create security typographic designs based on pseudo random screening element, liniature and screening angle choice. Screening with the help of originally designed screening element forms – alphabetic characters is also introduced. Pictograms in the form of characters have been designed with the goal of creating specially formed screening elements. Measurements have been made as to the covering capacity of all characters belonging to some fonts, and they have been successfully used as screening elements that produce reproductions in a new manner. Pixel program deformations were carried out that provide additional protection against efforts to counterfeit securities. With the use of several different random number generators, complete independence of certain parameters in the programs is achieved, and the security characteristics of such solutions are improved. The advantages of typography over linear graphics are proven in the area of document security. During research work the area of graphics linked with the infrared spectre area has also been entered in order to investigate the possibilities in creating security typographic information in this area too. With the development of device, instruments and tools the possibilities of security counterfeiting are growing, so the need for new security elements and forms of protection is especially pronounced.
