Printing can be a process whereby text and pictures are reproduced on various materials. There are different printing methods and with regards to the printing method a variety of inks are employed. Inks used in printing can be classified into 4 different categories like aqueous, liquid, paste and powder.

Paste inks:

Paste is frequently used for offset printing and there are different types of paste inks including cold set, heat set and energy curable ones. A number of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable provides the highest quality print, heat sets are commonly used. Energy curable ones also require special equipment so that it is just about the most expensive types of inks applied to offset printing.

The temperature set one requires heat to put it then it really is cooled rapidly as it catalyses the curing process. In cold set inks, it's set by using the phenomenon of absorption into the stocks which can be non-coated. Cold set ones are usually useful for printing books, newspapers, insert printing and so are the most affordable option if you're within a strict budget.



Solvent ink:

Solvent ink comprises a mixture of organic chemical substances and volatile organic compounds. These elements have high vapour pressure and colour in this type of ink is achieved through pigments causing them to be resistant to fading. Solvent inks enables you to print on uncoated vinyl substrates and they're cost-effective. Banners, billboards, graphics and decals are generally printed using solvent ink. The benefit of using solvent ink for printing would be that the prints are UV resistant and waterproof though the downside to by using this is the disposal of the solvent and the vapour created by the solvent.

Aqueous ink:

Aqueous inks are primarily applied to desktop inkjet printers. These comprise a combination of pigments or dyes, glycol and water. Aqueous provide the vivid and a variety of colour options the one problem with this ink is it is just not waterproof and is washed outside the surface without lamination or specialized coating to protect some of it. Aqueous inks are also inexpensive to produce.

UV curable inks:

UV curable inks have acrylic monomers coupled with an initiator package. Following the printing job is done the printed material is subjected to strong UV light which cures a lot of it. The main advantage of this ink would it be dries quickly and also the disadvantage is they are extremely expensive.

They are some of the various kinds of inks used for commercial printing services.
