Abstract

Individualizirani rasterski oblici nalaze svoju široku primjenu u projektiranju dokumenata i vrijednosnica. Posebno programirani oblici se, osim u svrhu zaštitne primjene, mogu koristiti i kao dizajnerski element pri manipulaciji fotografijama, portretima, izradi individualizirane grafike i tipografije na osobnim dokumentima. U ovom diplomskom radu odredit će se postupak modeliranja individualiziranog rasterskog elementa pomoću matematičkih funkcija. Matematički model rasterskog oblika biti će opisan u trodimenzionalnom i dvodimenzionalnom prikazu originalnog, individualiziranog rastera. Detaljnije će se razraditi sam način modeliranja rasterskog elementa preko programiranja njegovog pripadajućeg koda u programskom jeziku PostScript. Predlažu se različite implementacije novog rastera u piksel grafiku osobnog portreta. Uvođenje stohastičkih varijabli dodatno otežava pokušaj reprodukcije. Kombinacijom različitih, promjenjivih parametara kao što su linijatura i kut rastriranja, dobivaju se autentična rješenja koja je nemoguće reproducirati bez poznavanja svih veličina i parametara kojima se relacija rastera može obogatiti. U radu se daju individualizirana rješenja i primjene na portretima kao rješenjima za osobne dokumente ali i vrijednosnice. Originalne reprodukcije individualizirane kroz PostScript programska rješenja otežavaju reprodukciju i krivotvorenje portreta.

Abstract in english:	Individualized screen elements find their wide usage in designing documents and securities. Except for the purpose of protecting the application, specially programmed screens can be used as a design element in manipulation with photographs, portraits, individualized graphics and typography on personal documents. This thesis will determine the method of modeling individualized screen element using mathematical functions. Mathematical model of raster form will be visualized in three-dimensional and two-dimensional representation of the original, individualized screen element. Way of modeling the screen element will be worked out in detail by its corresponding programming code in a PostScript programming language. Different implementations of the new raster form are being suggested in pixel graphics of personal portraits. The implementation of stochastic variables complicates the attempt of reproduction even further. Combining different, changing parameters such as screen ruling and angle we get authentic solutions that are impossible to reproduce without knowing all the values and parameters that can enrich relation of screen element. This thesis provides individualized solutions and applications in portraits as solutions for personal documents as well as securities. Original graphic products individualized through PostScript software solutions make portraits difficult to reproduce and counterfeit.
