Sažetak
The area of individual screening has a wide field of application from designing the graphics of documents and securities to independent designer actions. In this paper new screen elements (SE) have been given systematically and their border conditions have been researched in respect to the design of contemporary computer graphics and reproduction. Screening is concentrated on stochastic method application. The method of pseudorandom choice of the screen element shape has been introduced, as well as that of rastering frequency choice, and rastering angle choice. The area of mutant SE is introduced ; i.e. the SE that change their shape depending on the halftone range. In case of reproducing a color image the possibility is stressed to design programmed joining of different color channels with choise of SE. It is proposed to use positive and negative deformation of SE from the same set, and in the same position for different color channels. The paper gives algorithms that rip the image and its image elements through new mutant screen elements in order to enable full application of the printing form for all printing types.
