Printing could be a method whereby text and pictures are a unit reproduced on varied materials. There are a unit completely different printing ways and looking on the printing methodology differing kinds of inks are a unit used. Inks utilized in printing are classified into four completely different classes like liquid, liquid, paste and powder.
Paste inks:
Paste is commonly utilized in offset and there are a unit differing kinds of paste inks like cold set, heat set and energy curable ones. a number of the various energy curable kinds are a unit electromagnetic wave curable and ultraviolet curable. Whereas energy curable offers the best quality print, heat sets are a unit most ordinarily used. Energy curable ones conjointly need special instrumentality that makes it one in every of the foremost costly varieties of inks utilized in offset.
The heat set one needs heat to line it then it's cooled quickly because it catalyses the hardening process. In cold set inks, it's set by victimization the development of absorption into the stocks that are a unit non-coated. Cold set ones are a unit typically used for printing books, newspapers, insert printing and are a unit the foremost value effective possibility if you're on a good budget.
Solvent ink contains a mix of organic chemical compounds and volatile organic compounds. These ingredients have high force per unit area and colorize this sort of ink is achieved through pigments that makes them immune to attenuation. Solvent inks are wont to print on uncoated vinyl substrates and that they are a unit value effective. Banners, billboards, graphics and decals are a unit generally written victimization solvent ink. The most advantage of victimization solvent ink for printing is that the prints are a unit actinic radiation resistant and waterproof but the drawback to victimization this can be the disposal of the solvent and also the vapors made by the solvent.
Aqueous ink:
Aqueous inks are a unit primarily utilized in desktop inkjet printers. These comprise a mix of pigments or dyes, glycol and water. liquid provide the vivid and a range of color choices the sole disadvantage of this ink is that it's not waterproof and might be washed far away from the surface while not lamination or specialized coating to shield the ink. Liquid inks also are cheap to manufacture.
UV curable inks:
UV curable inks have acrylic monomers let alone a leader package. When the printing job is completed the written material is exposed to sturdy ultraviolet light that cures the ink. The most advantage of this ink is that it dries quickly and also the disadvantage is that they're terribly costly.
