Printing is often a process whereby text and pictures are reproduced on various materials. There are various printing methods and with regards to the printing method several types of inks are used. Inks applied to printing might be classified into 4 different categories such as aqueous, liquid, paste and powder.
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 supplies the best quality print, heat sets are most commonly used. Energy curable ones also require special equipment which makes it just about the most expensive different types of inks used for offset printing.
Heat set one requires heat setting it then it can be cooled rapidly mainly because it catalyses the curing process. In cold set inks, it is set using the phenomenon of absorption to the stocks which might be non-coated. Cold set ones usually are used for printing books, newspapers, insert printing and therefore are the most affordable option if you’re cheaply.
Solvent ink comprises a variety of organic compounds and volatile organic compounds. These elements have high vapour pressure and colour in this kind of ink is achieved through pigments driving them to resistant against fading. Solvent inks can be used to print on uncoated vinyl substrates and they are cost effective. Banners, billboards, graphics and decals are generally printed using solvent ink. Lower than replacement using solvent ink for printing is that the prints are UV resistant and waterproof however the disadvantage to employing this may be the disposal with the solvent and also the vapour manufactured by the solvent.
Aqueous inks are primarily used for desktop inkjet printers. These comprise a mixture of pigments or dyes, glycol and water. Aqueous offer the vivid plus a selection of colour options the only problem with this ink would it be is just not waterproof and could be washed outside the surface without lamination or specialized coating to protect some of it. Aqueous inks can also be inexpensive to manufacture.
UV curable inks:
UV curable inks have acrylic monomers in conjunction with an initiator package. Following your printing job is done the printed materials are encountered with strong UV light which cures the ink. The main advantage of this ink is it dries quickly and the disadvantage is they are very expensive.
They’re some of the various kinds of inks used for commercial printing services.
