Inks utilised in printing may be classified into 4 different categories including aqueous, liquid, paste and powder.
Paste is often utilised in offset printing and there are several types of paste inks like cold set, heat set and curable ones. A few of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable offers the highest quality print, heat sets are most frequently used. Energy curable ones also require special equipment that makes it probably the most expensive different types of inks used in offset printing.
Heat set one requires heat to put it then it’s cooled rapidly because it catalyses the curing process. In cold set inks, it’s set using the phenomenon of absorption in the stocks which are non-coated.

Aqueous offer the vivid along with a selection of colour options the one drawback to this ink is it is just not waterproof and could be washed away from the surface without lamination or specialized coating to shield some of it. Aqueous inks will also be inexpensive to make.
UV curable inks:
UV curable inks have acrylic monomers in conjunction with an initiator package. Following your printing job is fully gone the printed materials are encountered with strong UV light which cures a lot of it.
