Sažetak
Through this paper a family of sinusoidal screening elements is defined and we explore possibilities of their application in graphic arts, securities printing and design solutions in photography and typography editing. Mathematical expressions of sinusoidal families were converted into a Postscript language. The introduction of random variable results in countless number of various mutations, which can not be repeated without knowing the programming code itself. Therefore, the use of the family of screens in protection of securities is of great importance. Other possible application of the modulated sinusoidal screens is in large format color printing. This paper will test application of the sinusoidal screens in vector graphics, pixel graphics and typography. Development of parameters in the sinusoidal screen element algorithms gives new forms defined within the screening cells with strict requirements of coverage implementation. Individual solutions include stochastic algorithms as well as autonomy of screening forms in regard to multicolor printing channels.
