Abstract

Kada se govori o pojmu raster tada se misli na sredstvo pomoću kojeg se vrši rastriranje. Kao produkt rastriranja nastaje rasterski element. U ovom diplomskom radu promatrat će se ponašanje rasterskih elemenata na različitim tiskovnim podlogama koje će biti otisnute tehnikom fleksotiska. Fleksotisak spada u tehniku visokog tiska i vrlo je popularna tehnika tiska zbog iznimne pogodnosti tiskanja na različitim tiskovnim podlogama. Osim toga, fleksotisak karakterizira odlična kvaliteta u pratnji povoljnih cijena, brzi proces otiskivanja, mogućnost korištenja bojila na bazi vode, na bazi otapala te UV bojila, veći nanos i dobra pokrivnost boja te jednostavnost tehnike tiska s kratkom pripremom za proizvodnju. Fleksotisak će u radu biti obrađen kroz poglavlja koja će opisivati njegovu povijest, strojeve koji se koriste, prednosti i nedostatke, boje i podloge koje su pogodne za proces tiska. Također će se u radu spomenuti rastriranje te nepravilnosti i deformacije rasterskih elemenata te razlozi zbog kojih do istih dolazi. U eksperimentalnom dijelu diplomskog rada pomoću mikroskopa će biti utvrđena manja odstupanja i deformacije rasterskih elemenata kod različitih vrsta podloge usprkos jednakim uvijetima tiska odnosno jednakom pritisku stroja i jednakim bojama, a razlog tome leži u činjenici da su karakteristike pojedine vrste podloga vrlo bitan faktor i da se ista boja ipak svojim sastavom mora prilagoditi vrsti podloge za koju se koristi.

Abstract in english:	When speaking of term screen, then it's meant about the technique of screening. As a result of screening, a screen element is made. In this thesis, screen element on different printing surfaces printed in fleksoprinting technique will be observed. Fleksoprinting appertains to letterpress printing and it is very popular technique due to its extraordinary convenience of printing on different printing surfaces. Except for that; fleksoprinting is characterized by excellent quality which is followed by favorable prices, fast printing process, ability of usage water based dyes, solvent and UV colorants, good color coverage, and simplicity of this printing technique with short preparation for production. Fleksoprinting in this thesis will be processed through chapters which will describe its history, machines that are used nowadays, advantages and disadvantages, dyes, colorants and surfaces which are suitable for printing process. Also will be mentioned screening, deformations of screen elements and reasons why do these deformations occur. In experimental part of this thesis, by usage of microscope, small aberrations and deformations of screen elements at different types of surfaces despite of equal conditions of printing, apropos equal machine pressure and dyes, will be observed. Reason for that lies in fact that characteristics of individual type of surface is relevant factor and fact that same dye has to adjust towards surface for which is used.
