Sažetak
The Inkjet printing technology has found widespread application across diverse industries, particularly in graphic and textile printing. The crucial role of the Inkjet head in achieving precise prints cannot be overstated. The selection of the inkjet head significantly influences the homogeneity of the printed surface and the realization of screen elements. Furthermore, the inkjet printing principle's potential for adhesion of metalized foils through a digital foiling process necessitates a detailed investigation into the influence of commercial piezo Inkjet heads. In this study, we present a method for testing the efficiency of achieving four-sized metalized gold foil printing lines on standard mat-coated cardboard printing substrates, both in the machine direction and cross direction. The experiment involves the gradual variation of the amount of UV-cured Inkjet varnish. Utilizing three different thicknesses of UV-cured varnish (21 μm, 36 μm, and 51 μm) in conjunction with modular piezo inkjet heads KM1024 iLHE-30 and print speeds according to varnish thickness (0,300 m/s, 0,24 m/s and 0,182 m/s). Research demonstrates that a 21 μm layer thickness of UV varnish combined with cross-direction movement ensures optimal production of digital metalized foil lines. Additionally, our results confirm the superior potential of a larger varnish application for line reproduction and enhanced contrast.
