Abstract
Implementiranjem novih mogućnosti u postojeće programe za stolno izdavaštvo moguće je optimizirati procese digitalne grafičke pripreme. Skriptni programi koji izvršavaju izradu prijeloma, pod određenim uvjetima, mogu ubrzati i automatizirati digitalnu grafičku pripremu te smanjiti broj pogrešaka kod formatiranja dokumenta. Temeljem analize proizvodnih procesa izneseni su kriteriji pri odabiru procesa digitalne grafičke pripreme za optimizaciju korištenjem skriptnih tehnologija. Predloženi su novi modeli za rješavanje složenih zadataka grafičke pripreme kojima se unaprjeđuju postupci ubacivanja, zamjene i oblikovanja teksta i slika, ispravljanja pogrešaka u tekstu, izrade automatiziranog prijeloma periodičkih publikacija, automatizacije radnih procesa baziranih na XML-u, izrade montaže u programu za prijelom, individualizacije i varijabilne grafičke pripreme. U radu se novi izrađeni modeli za poboljšanje procesa u grafičkoj pripremi vrednuju naspram standardnih procesa te se određuje nivo optimizacije mjerenjem vremena, određivanjem stupnja postignute automatizacije te određivanjem pouzdanosti standardnih i unaprjeđenih modela rada. Iz izvedenog istraživanja donijeti su zaključci o uštedama i prednostima koje se dobivaju upotrebom skriptnih tehnologija te uvjeti za optimalnu upotrebu u standardnim programima i metodama rada.

| Abstract in english: | For quite some time the printing business has been under heavy pressure because of overcapacity, dropping prices and the delocalization of the production to low income countries. The graphic communications industry, like most other "manufacturing" industries has increased pressure to drive cost down while simultaneously providing automation. Every step in the graphic communications value chain is under scrutiny and a candidate for refinement. To survive in this competitive world, printers have to invest in tools that reduce production costs, create additional value for their customers and automate production processes. Automation of workflow processes can provide tremendous value both in terms of operational efficiency and revenue growth. The benefit of automation in graphic prepress lies primarily in an increase of efficiency in the production of layout and imposition of repetitive tasks by shortening lead time. Another benefit is cost reduction, since more work can be done with fewer staff members. Prepress processes can be optimised by implementing new features in the existing desktop publishing programs. Scripting programs that execute layout process under certain conditions can accelerate, automate and reduce the number of errors in digital prepress when formatting documents. The main purpose of these theses is to spread the idea about computer work optimisation in graphic prepress workflows. This research proves that improvements in graphic prepress processes can be obtained by implementing new suggested models which use scripting languages. Scripts can be written to execute just one task, complex scripts can perform multiple tasks and some scripts automate the entire publishing process. New models for solving complex tasks are proposed to enhance procedures of inserting, replacing and formatting text and images, correcting errors in the text, making automated layout of periodicals, automation of work processes based on XML, making impositions in the layout program, individualization and variable prepress. Quantitative research was carried out to determine achieved automation and time reduction by using optimised processes. Prepress models for process improvement are evaluated against standard processes, and the level of optimization is determined by measuring time, automation and reliability levels of standard and enhanced models of operation. This proves the hypothesis that features of workflow processes which quantify savings and benefits can be determined. From conducted analysis of digital prepress 10 new script workflow models were made. Each model was evaluated against standard production of the task. By graphic prepress analysis and script execution evaluation findings about criteria in process selection for optimisation with scripting technologies were made. Thesis also highlights savings and benefits of using scripting technologies in graphic prepress. Thesis proves that by replacing only certain tasks it is possible to automate digital prepress processes since there are tasks that cannot be optimised. By analysis such tasks were described. Special interest is given to the hypothesis which states that by adding new script models to graphic prepress complex tasks that are otherwise hard to address can be optimally achieved. The hypothesis was proven by implementing scripts that add new functionality to the production in standard prepress programs. With scripts that execute complex tasks execution period can be time consuming. This paper also deals with written script optimization in order to shorten the time of its execution and to identify factors that affect the script execution time. |
