Abstract

Odrţivi razvoj je znaĉajni ĉimbenik prepoznatljiv i u domeni grafiĉkog dizajna. Pristup dizajnu kroz ţivotni ciklus proizvoda i strategiju minimalne potrošnje resursa, korištenje materijala s malim utjecajem na kvalitetu okoliša, proizvodnju bez nastanka otpada, optimizacija ţivotnog vijeka proizvoda, osigurati će društveni razvoj na Zemlji sa zdravim okolišem i konkurentnim gospodarstvom. Potrebno je znanje i komunikacija, te istraţivanja i novi pristup prema okolišu da bi osigurali razvoj koji udovoljava potraţnju sadašnjosti bez ugroţavanja budućih generacija da udovolje svoje potrebe. U ovom radu sa aspekta dizajna prikazan je odabir materijala i tehnika tiska kroz ţivotni ciklus grafiĉkog proizvoda u smjeru zatvaranja sustava prema postavci od „kolijevke do kolijevke“. Svrha rada je utvrditi moţe li se promjenom uvjeta u digitalnom ofsetnom tisku postići recikliranje otisaka zadovoljavajuće kvalitete vlakanaca za izradu finih grafiĉkih papira, uz uvjet da otisci ne gube na kvaliteti. Sva dosadašnja istraţivanja upućuju na problematiĉno recikliranje digitalnih otisaka na osnovi elektrofotografije s tekućim tonerom. Za otiskivanje je odabrana digitalna tehnika tiska na osnovi elektrofotografije s tekućim i krutim tonerom. U ĉetvrtoj fazi indirektne elektrofotografije kod prvog transfera boje varirana je temperatura ofsetnog cilindra. U ovoj fazi tiska ĉestice tonera se s fotokonduktorske površine prenašaju na prijenosni medij - ofsetni cilindar. Temperatura je mijenjana u intervalu 1250C - 1450C. Za recikliranje otisaka primijenjena je alkalna kemijska deinking flotacija. Rezultati istraţivanja ukazuju na manju efikasnost odstranjivanja bojila s otisaka HP Indiga TurboStream (smanjenje broja ĉestica 31% - 59% i površine 45% - 55% u ovisnosti o temperaturi ofsetnog cilindra) u odnosu na otisak dobiven digitalnom tehnikom s krutim tonerom (smanjenje broja ĉestica 90% i površine 98%). U radu se diskutira specifiĉnost mehanizma procesa u odnosu na karakteristike tiska, uz tumaĉenje rezultata dobivenih funkcionalnom ovisnošću ERIC-a i svjetline listova prema fazama procesa recikliranja.

Abstract in english:	Sustainable development is a very important factor, also recognizable in the domain of graphic design. Approach to design through product's life cycle and minimal resource consumption strategy, together with exploitation of materials with low impact on quality of environment, production that does not produce waste, and optimalisation of product's lifespan will secure Earth's social development with a healthy environment and competitive economy. Knowledge and communication, research and new approach towards environment are required for securing development that can satisfy present demand without endangering future generations. This paper presents a selection of materials and printing techniques from a design point of view through life cycle of graphic product, in direction of closing the system according to thesis „from cradle to cradle“. Purpose of this paper is to determine whether the modification of conditions in recycling of digital offset print can produce fibers of satisfactory quality for manufacturing fine graphic paper, under the condition that prints do not lose quality. All research up to now shows problems in recycling of digital prints on bases of electro photography with liquid toner. Digital print technique on basis of electro photography with liquid and solid toner is selected for printing. Temperature of the offset cylinder in first ink transfer of phase four of indirect electro photography is variable. In this printing phase particles of toner are transferred from photo conductory surface on portable medium-offset cylinder. Temperature was changed between 125 and 145 degrees Celsius. Method used for recycling of prints was alkali chemical de-inking flotation. Results of research are showing smaller effectiveness in ink removal from HP Indigo Turbo Stream prints (number of particles decreased by 31 - 59% and overall particle surface reduced by 45 - 55%, depending on temperature of offset cylinder), compared to prints made using digital technique with solid toner (number of particles decreased by 90% and overall particle surface reduced by 98%). This paper discusses specific qualities of process mechanisms regarding printing characteristics, with interpretation of results gained by functional dependence of ERIC and sheet brightness in relation to phases of recycling process.
