Komparacija karakteristika ink-jet otisaka dobivenih vodenim, solventnim i UV bojilima

Razvojem digitalnih sustava obrade i prijenosa podataka i u grafičkoj tehnologiji je došlo do radikalnih promjena u orijentaciji grafičke struke sa prethodnoga usmjerenja primarno orijentiranog prema strojarstvu i kemijskoj tehnologiji, prema informacijskim i digitalnim tehnologijama. Tako se ističu CtP tehnologije, a posebno, nakon najzastupljenije elektrofotografske tehnologije, ink-jet tehnologija tiska, koja se pokazala posebno pogodnom prilikom tiska, primjenom različitih vrsta bojila, na različite materijale bez obzira na strukturu ili debljinu tiskovne podloge. Ink-jet tehnika je vrlo rasprostranjena. Susrećemo ih od malih pisača, pa sve do strojeva koji tiskaju i do 20 metara duge gigantografije (npr. plakati uz prometnice). Najčešće tehnologije inkjet tiska jesu: termički ink-jet (Bubble Jet), piezo ink-jet, a nerijetko se susreće elektrostatski ink-jet [1]. Ink-jet tehnika tiska je u stvari pravi beskontaktni tisak. Na signal iz računala, kapljica bojila iz mlaznice dolazi na tiskovnu podlogu te ispisuje red po red otiska. Danas su tehnika i tehnologija toliko uznapredovale da se mogu ostvariti otisci vrlo visoke kvalitete, pri čemu tisak kolor ne predstavlja nikakav problem ni na različitim vrstama tiskovnih podloga.
With the development of the digital data processing and transfer systems, graphic technology experienced radical changes in the graphic profession’s orientation. Its direction changed from being primarily oriented towards civil engineering and chemical technology to being oriented towards the information and digital technologies. Thus the CtP technologies are pointed out – after the predominant electro photographic technology, the ink-jet printing technology in particular. It proved as particularly suitable in printing with various types of dyestuff on various materials regardless the structure or the thickness of the printing base. The ink-jet technique is very widespread. It can be found in the whole range of printers – from the small ones up to the machines that can print up to 20 meters long giantographs (exp. billboards beside the roads). The most often technologies of the ink-jet printing are: the thermal ink-jet (Bubble Jet), piezo ink-jet, and, not rarely, one can find the electrostatic ink-jet [1]. The ink-jet printing technique is actually the real contactless print. At the signal from the computer a drop of ink from the nozzle comes to the printing base and prints one printing line after another. Today the technique and technology are so advanced that one can make prints of very high quality, whereby printing in colour does not represent any problem even on the various types of printing materials.
