Abstract
U grafičkoj industriji iznimno je bitna vjerodostojna reprodukcija, stoga i postupak vrednovanja dobivenog otiska mora biti što pouzdaniji. Cilj istraživanja je usporedba rezultata mjerenja dobivenih spektrofotometrom koristeći Murray-Daviesov, odnosno Yule-Nielsenov model za opis rastertonske slike. Murray-Daviesov model pretpostavlja jednoliko obojenje podloge i izotropnu podlogu. Zanemarenje raspršenja svjetlosti jedno je od glavnih razloga netočnosti Murray-Daviesovog modela. Usklađivanje, nazvano Yule-Nielsenova korekcija uvedeno je za tiskane podloge kod kojih dolazi do difuznog raspršuje. Pretpostavka je da će mjerenja provedena korištenjem Yule-Nielsenovog algoritma za različite vrijednosti parametra n značajno odstupati od mjerenja dobivenih Murray-Daviesovim algoritmom.

| Abstract in english: | In the graphics industry, credible reproduction is extremely important, therefore the process of evaluating the obtained print must be as reliable as possible. The aim of the research is to compare the measurement results obtained with a spectrophotometer using the Murray-Davies and Yule-Nielsen models, respectively, to describe the rasterton image. The Murray-Davies model assumes uniform substrate coloration and an isotropic substrate. Neglect of light scattering is one of the main reasons for the inaccuracy of the Murray-Davies model. Alignment, called Yule-Nielsen correction, was introduced for printed media in which diffuse scattering occurs. It is assumed that the measurements performed using the Yule-Nielsen algorithm for different values of the parameter n will deviate significantly from the measurements obtained by the Murray-Davies algorithm. |
