Abstract

Prilikom uporabe različitih postupaka izrade tiskovnih formi, te realizacije

reprodukcija u istim kontroliranim uvjetima, moguće su promjene tiskovnih elemenata

na tiskovnim formama koje mogu utjecati na različitost krivulja reprodukcija boja i

tonova na realiziranim reprodukcijama. Većina uređaja za CtP postupak izrade

tiskovnih formi radi s velikim kapacitetom osvjetljavanja i razvijanja.

Mjerenje pokrivenosti uređajem iCPlate II za kontrolu kvalitete tiskovnih formi

pokazalo je da pokrivenost polinomski raste s porastom RTV za sve ispitivane

uzorke. Mjerenja su pokazala da pri niskim RTV dolazi do smanjenja RTV zavisno o

otisnutoj nakladi, dok pri višim RTV dolazi do povećanja RTV. Izuzetak čini

pokrivenost površine kod velikih naklada gdje je smanjenje pokrivenosti pri niskim

RTV uzrokovano i djelomičnim trošenjem tiskovne forme.

Abstract (english)

During the usage of different printing plates, and the realisation of

reproductions under the same controled conditions, there are some printing elements

changes possible on printing plates which can affect to colours and tones

reproduction locus variety on realised reproductions. Most of the devices for CtP

process of making printing forms works with great capacity of brightnes and

development.

Measurments with iCPlate II for control of quality of printing plates has

indicated that coverage is polimomly increasing by increasing of raster tone value for

all of speciments. Measurments indicated that in low raster tone values, they are

decreasing depending on publishing edition, while in high raster tone values, raster

tone values are increasing. Exception is coverage of high editions where decrease of

coverage in lower raster tone values is partially caused by printing plates being worn

out.
