Abstract

Vecina grafickih proizvoda danas se tiska u ofsetnoj tehnici tiska. Glavni problem s kojim se susrecu mnoge tiskare, jest dobiti što vjerniji otisak u odnosu na original. Jedan od glavnih faktora koji utjece na reprodukciju je tiskovna podloga. U teoretskom dijelu biti ce opisani princip ofsetnog tiska, priprema ofsetnog stroja za tisak, kontrola kvalitete tiska te prirast rastertonskih vrijednosti. U prakticnom dijelu istraživanja korišteni su uzorci tiskani na istom tiskarskom stroju, u identicnim uvjetima, te na tri razlicite vrste papira. Korištena su konvencionalna bojila za višebojni ofsetni tisak. Mjerenja su vršena denzitometrom, a mjerile su se integralne gustoce obojenja punih polja te polja rastertonskih vrijednosti. Na temelju dobivenih rezultata mjerenja ustanovljen je utjecaj razlicitih vrsta papira na prirast rastertonskih vrijednosti.

Abstract (english)

Most graphic products today are printed in offset printing technique. The main problem which many printing houses are dealing with, is how to get more identical print in relation with an original. One of the main factors which affect the reproduction is a printing material. In theoretical part, principle of offset printing, makeready of offset machine, control of printing quality and dot gain will be described. Samples used in practical part of the research were printed on the same printing machine, at indentical conditions and on three different types of paper. Conventional offset inks for multicolor printing were being used. Colour density and dot area were measured by densitometer. According to obtained measuring results, influence of different types of paper on dot gain has been established.
