    Printing is a process whereby text and pictures are reproduced on various materials. There are numerous printing methods and depending on the printing method a variety of inks are used. Inks applied to printing can be classified into 4 different categories for example aqueous, liquid, paste and powder.

    Paste inks:

    Paste can often be applied to offset printing and there are various kinds of paste inks such as cold set, heat set as well as energy curable ones. A few of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable supplies the best quality print, heat sets are commonly used. Energy curable ones also require special equipment so that it is the most expensive types of inks applied to offset printing.

    Heat set one requires heat to set it after which it is cooled rapidly mainly because it catalyses the curing process. In cold set inks, it is set with the phenomenon of absorption in to the stocks which might be non-coated. Cold set ones are generally employed for printing books, newspapers, insert printing and are the least expensive option in case you are cheaply.

    Solvent ink:

    Solvent ink comprises a variety of organic substances and volatile organic compounds. These elements have high vapour pressure and colour in this type of ink is achieved through pigments making them resistance against fading. Solvent inks can be used to print on uncoated vinyl substrates and they’re economical. Banners, billboards, graphics and decals are usually printed using solvent ink. The main advantage of using solvent ink for printing could be 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 ink:

    Aqueous inks are primarily used for desktop inkjet printers. These comprise a variety of pigments or dyes, glycol and water. Aqueous provide the vivid along with a selection of colour options the only downside of this ink could it be is not waterproof and can be washed out of the surface without lamination or specialized coating to shield a lot of it. Aqueous inks are also inexpensive to make.

    UV curable inks:

    UV curable inks have acrylic monomers along with an initiator package. Following the printing job is done the printed material is exposed to strong UV light which cures the ink. Lower than replacement this ink could it be dries quickly and the disadvantage is that they are very expensive.

    These are many of the various kinds of inks applied to commercial printing services.
