Many of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable provides best quality print, heat sets are commonly used. Energy curable ones also require special equipment so that it is just about the most expensive categories of inks applied to offset printing.
The warmth set one requires heat to set it then it really is cooled rapidly because it catalyses the curing process.
