eng	UV/EB INKS AND VARNISHES IN PRINTING INDUSTRY	This paper reviews the different mechanisms of UV inks curing (free radical, cationic and hybrid polymerization). The advantages and disadvantages of these various types of UV inks are discussed together with their applications areas. Next, the various UV sources used for curing of these inks are outlined. The text describes mercury lamps, doped mercury lamps, excimer lasers and also UV LEDs. UV LEDs are potentially very interesting UV source, which may in the future replace existing sources in some applications. The last part is focused on EB inks. In the text the curing mechanism, applications areas and their comparison with UV inks are explained.	UV ink; EB ink; UV source; cationic polymerization; radical polymerization
