Printing is really a process whereby text and pictures are reproduced on various materials. There are several printing methods and with regards to the printing method several types of inks are employed. Inks utilised in printing may be classified into 4 different categories such as aqueous, liquid, paste and powder.

Paste inks:

Paste is usually used for offset printing and there are several types 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 highest quality print, heat sets are most commonly used. Energy curable ones also require special equipment rendering it probably the most expensive categories of inks used for offset printing.

Heat set one requires heat to create it then it is cooled rapidly since it catalyses the curing process. In cold set inks, it is set utilizing the phenomenon of absorption to the stocks which are non-coated. Cold set ones are often used for printing books, newspapers, insert printing and are the most affordable option if you’re on a tight budget.

Solvent ink:

Solvent ink comprises a mixture of organic chemical compounds and volatile organic compounds. These elements have high vapour pressure and colour in this kind of ink is achieved through pigments which makes them resistant against fading. Solvent inks enables you to print on uncoated vinyl substrates and they are affordable. Banners, billboards, graphics and decals are usually printed using solvent ink. Lower than replacement using solvent ink for printing would be that the prints are UV resistant and waterproof even so the disadvantage to employing this could be the disposal from the solvent as well as the vapour manufactured 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 offer the vivid plus a number of colour options the only real downside of this ink is that it is not waterproof and is washed away from the surface without lamination or specialized coating to safeguard the ink. Aqueous inks are also inexpensive to produce.

UV curable inks:

UV curable inks have acrylic monomers in conjunction with an initiator package. Following the printing job is completed the printed materials are confronted with strong UV light which cures a lot of it. Is generally considerably this ink could it be dries quickly and the disadvantage is because are extremely expensive.

They are a few of the a variety of inks used for commercial printing services.
