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

Paste inks:

Paste is usually utilised in offset printing and there are a variety of paste inks for example cold set, heat set and energy curable ones. Many of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable offers the finest quality print, heat sets are used. Energy curable ones also require special equipment so that it is just about the most expensive different types of inks used in offset printing.

The warmth set one requires heat to create it then it is cooled rapidly since it catalyses the curing process. In cold set inks, it's set with the phenomenon of absorption to the stocks that are non-coated. Cold set ones usually are employed for printing books, newspapers, insert printing and so are the most affordable option if you are on a tight budget.

Solvent ink:

Solvent ink comprises a mixture of organic chemical substances and chemical toxins. These elements have high vapour pressure and colour in this kind of ink is achieved through pigments driving them to proof against fading. Solvent inks can be used to print on uncoated vinyl substrates and they're cost-effective. Banners, billboards, graphics and decals are normally printed using solvent ink. Lower than replacement using solvent ink for printing is that the prints are UV resistant and waterproof however the disadvantage in employing this could be the disposal of the solvent along with the vapour created by the solvent.

Aqueous ink:

Aqueous inks are primarily used for desktop inkjet printers. These comprise a mixture of pigments or dyes, glycol and water. Aqueous provide vivid plus a variety of colour options the only downside of this ink is that it is just not waterproof and can be washed outside the surface without lamination or specialized coating to protect some of it. Aqueous inks can also be inexpensive to make.

UV curable inks:

UV curable inks have acrylic monomers along with an initiator package. After the printing job is finished the printed materials are encountered with strong UV light which cures some of it. Is generally considerably this ink is that it dries quickly along with the disadvantage is that they have become expensive.

They're some of the several types of inks utilised in commercial printing services.
