In recent years it has become necessary to double check what exactly is meant when somebody talks about UV-Offset. Nowadays it is not merely UV-Offset printing.

We can find H-UV from Komori, while Manroland is marketing LEC-UV. KBA calls it HR-UV and to Heidelberg, it is LE-UV. Additionally UV inks can be cured with even less energy input by using LED-UV, with Ryobi being a pioneer in this technology. What do all these curing processes have in common and what makes them different?
