Printing inks that are cured by electron beams. Similar to UV inks, which are cured by ultraviolet light, EB inks are cured by means of polymerization. This is brought about by the direct effect of the electrons on polymerizable substances. Unlike UV inks, special initiators are not required for EB inks. As a result, EB inks are better in storage. Their special advantage is considered to be the option of processing them in thick layers, because the electron beams penetrate deeply. However, curing must be carried out in an oxygen-free environment (under a gas blanket) in order to avoid oxidation of the ink and the printing material caused by the high-energy electrons.
