Abstract

Papiri koji se dugo zadržavaju u skladištu ili se koriste dugo nakon dostave korisniku, starenjem mijenjaju svojstva upojnosti boje u strukturu podloge i otpornosti površine na otiranje. Te promjene utječu na otisak, odnosno otisak ima različite karakteristike. Ink jet i laser ispis su tehnike ispisa koje su najrasprostranjenije u kućanstvima i uredskoj upotrebi. Uvjeti tih tehnika moraju zadovoljavati određene uvjete, kao što su kompatibilnost tiskovne boje, reološka svojstva, kemijske karakteristike, odgovarajuće karakteristike tiskovne podloge, papira. Tehnika slikovne analize primjenjuje se u raznim znanstvenim područjima. Odlikuju je jednostavnost korištenja, prilagodljivost, dostupnost na različitim platformama (Windows, Mac OS X, Linux x86, 64-bit Windows) i dostupnost različitih softverskih rješenja. U području grafičke tehnologije slikovna analiza se najviše koristi u ispitivanjima papira i otisaka. U ovome radu provedena je karakterizacija tri vrste improvizirano starenih i nestarenih papira, odnosno Navigator, Brunnen i Permanentnog papira tiskanih ink jet i laserskom tehnikom tiska. Napravljena je slikovna analiza odabranih elemenata testne forme i provedeno je istraživanje otpornosti otiska na otiranje Pirra Wallace uređajem i upojnosti Cobb-ovom metodom.

Abstract in english:	Paper which is long kept in storage or it’s used long time after delivery to the user, changes characteristics of whiteness, ink absorption and rub resistance, whit reference the print has different characteristics. Ink jet and laser prints are print technics which are prevailed in home and commercial use. These print technics are one of the most resarched and observe. Requirement of these technics have to meet the conditions, like ink compatibility, rheology attributes, chemical characteristics, suitable characteristics of subtrate, paper. Image analyzing tehnics are applied in miscellaneous scientific areas. It’s attributed by simply way of use, diversity, availability on different platforms (Windows, Mac OS X, Linux x86, 64-bit Windows) and availability by different software solutions. In graphic operation array image analyze is the most used in testing paper and prints. This work conducts characterisation of three improvised old and normal paper, with reference to Navigator, Brunnen and Permanent papers printed on ink jet and laser technics. It has been made image analyze of selected elements of tested form and resarch of rub resistance of printing surface by Pirra Wallace device and ink absorption by Coob method.
