used. Inks used in printing could be classified into 4 different categories such
as aqueous, liquid, paste and powder.
Paste inks:
Paste can often be
used for offset printing and there are various kinds of paste inks such as cold
set, heat set as well as energy curable ones. A number of the different energy
curable sorts are electron beam curable and ultraviolet curable. While energy
curable provides top quality print, heat sets are most commonly used. Energy
curable ones also require special equipment that makes it just about the most
expensive kinds of inks used for offset printing.
The warmth set one
requires heat to create it and then it is cooled rapidly since it catalyses the
curing process. In cold set inks, it really is set using the phenomenon of
absorption to the stocks that are non-coated. Cold set ones are usually employed
for printing books, newspapers, insert printing and therefore are the most cost
effective option in case you are within a strict budget.

Aqueous provide you with the vivid plus a selection of colour options the only real drawback to this ink is it is just not waterproof and is washed out of the surface without lamination or specialized coating to protect a lot of it. Aqueous inks may also be inexpensive to manufacture.
UV curable inks:
UV curable inks have acrylic monomers coupled with an initiator package. Following your printing job is done the printed material is exposed to strong UV light which cures the ink. The benefit of this ink is that it dries quickly and the disadvantage is because are incredibly expensive.
These are many of the several types of inks applied to commercial printing services.
