    Printing is often a process whereby text and images are reproduced on various materials. There are several printing methods and based on the printing method various kinds of inks are widely-used. Inks used in printing might be classified into 4 different categories like aqueous, liquid, paste and powder.

    Paste inks:

    Paste is frequently applied to offset printing and you will find several types of paste inks such as cold set, heat set and curable ones. Some of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable supplies the top quality print, heat sets are most commonly used. Energy curable ones also require special equipment which makes it the most expensive kinds of inks utilised in offset printing.

    The heat set one requires heat to put it and then it is cooled rapidly since it catalyses the curing process. In cold set inks, it really is set by using the phenomenon of absorption into the stocks which are non-coated. Cold set ones are usually useful 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 combination of organic substances and chemical toxins. These components have high vapour pressure and colour in this kind of ink is achieved through pigments driving them to resistance against fading. Solvent inks enables you to print on uncoated vinyl substrates and they are cost-effective. Banners, billboards, graphics and decals are generally printed using solvent ink. The benefit of using solvent ink for printing would be that the prints are UV resistant and waterproof though the downside to employing this may be the disposal with the solvent and the vapour manufactured 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 along with a variety of colour options the sole drawback to this ink is it is just not waterproof and could be washed from the surface without lamination or specialized coating to guard the ink. Aqueous inks will also be inexpensive to fabricate.

    UV curable inks:

    UV curable inks have acrylic monomers in conjunction with an initiator package. After the printing job is completed the printed materials are subjected to strong UV light which cures the ink. Is generally considerably this ink would it be dries quickly and also the disadvantage is they are very expensive.

    These are a few of the a variety of inks used in commercial printing services.
