Abstract

Današnjom UV Inkjet tehnologijom tiska omogućena je alternativa otiskivanja limenih proizvoda. U ovom radu pokazati će se kolika je mehanička čvrstoća otisaka na metalnim čepovima otisnutih tehnikom Inkjeta sa tri različita stroja, odnosno Inkjet boje. Sukladno tome, otisci su podvrgnuti denzitometrijskim i spektrofotometrijskim mjerenjima, a nakon toga i mehaničkom oštećenju vršne površine. Eksperimentalno otisnuti uzorci posebno su konstruirani te sadržavaju veći broj različito obojenih kolornih polja uz varijaciju gradacije rastertonskih vrijednosti (različita tonska pokrivenost). Također, uzorci su sadržavali točno definirane PANTONE nijanse za detaljnije ispitivanje njihove kvalitete prilikom tiska na metal. Denzitometrijska kontrola provedena je kako bi se utvrdila kolorna kvaliteta otiska, odnosno kreirale krivulje reprodukcije. Iz dobivenih krivulja vidljivo je kako je reprodukcija na Roland printeru nešto tamnija, dok su otisci dobiveni na Durst printeru najumjereniji. Kako bi se odredila razlika između Inkjet UV sušećih bojila izvršena je međusobna komparacijska kolorimetrijska analiza. Iz promatranja njihovih različitosti, utvrđeno je da nema pravilnosti između otisaka, te se svaki ponaša osebujno. Nakon mjerenja, otisci su podvrgnuti mehaničkom oštećenju. Točnije, provedeno je ispitivanje Cross Cut testerom, te mehaničko otiranje. Oba ispitivanja su pokazala kako su otisci izuzetno stabilni na metalnoj podlozi, te su njihova oštećenja nakon ispitivanja minimalna.

Abstract (english)

Today's UV Inkjet printing technology has been enabled alternative of printing on metal surfaces. In this work it has been shown how strong are the prints on metal caps printed with Inkjet technology with three different Inkjet printing machines. Accordingly, the prints are primarily subjected to densitometric and spectrophotometric measurements, and then the mechanical surface damage. Experimental samples are specially designed and are contained greater number of differently colored fields to variation of certain dot gradation value (different tone coverage). Also, the samples contained PANTONE tones for a more detailed examination of their quality printing on metal. Densitometric control was conducted to determine the colour quality of the print. From the resulting print curve it has been showed that the reproduction at Roland Inkjet printer is darker, while the prints obtained with Durst Inkjet printer are the most moderate. In order to determine the difference between Inkjet UV inks it has been made mutual comparison colorimetric analysis. From observation of these differences, it was found no regularity between prints. After measurements, prints are subjected to mechanical damage. Specifically, the study was carried out with cross cut test, and were subjected to mechanical rubbing of the prints. Both tests showed that the prints are extremely stable on a metal substrate, and their damage after testing is minimum.
