Printing is really a process whereby text and pictures are reproduced on various materials. There are different printing methods and depending on the printing method several types of inks are widely-used. Inks utilised in printing could be classified into 4 different categories such as aqueous, liquid, paste and powder.
Paste is frequently used in offset printing and you will find various kinds of paste inks including cold set, heat set as well as energy 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 commonly used. Energy curable ones also require special equipment that makes it the most expensive different types of inks utilised in offset printing.
The temperature set one requires heat to set it and after that it can be cooled rapidly mainly because it catalyses the curing process. In cold set inks, it’s set by using the phenomenon of absorption in the stocks which might be non-coated. Cold set ones are usually useful for printing books, newspapers, insert printing and they are the most cost effective option in case you are within a strict budget.
Solvent ink comprises a combination of organic substances and chemical toxins. These components have high vapour pressure and colour in this type 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. Is generally considerably using solvent ink for printing could be that the prints are UV resistant and waterproof nevertheless the disadvantage to using this is the disposal with the solvent and the vapour produced by the solvent.
Aqueous inks are primarily utilised in desktop inkjet printers. These comprise a combination of pigments or dyes, glycol and water. Aqueous provide you with the vivid and a variety of colour options the one downside of this ink is that it is not waterproof and could be washed from the surface without lamination or specialized coating to shield the ink. Aqueous inks may also be inexpensive to manufacture.
UV curable inks:
UV curable inks have acrylic monomers as well as an initiator package. After the printing job is finished the printed material is exposed to strong UV light which cures some of it. The main advantage of this ink could it be dries quickly and the disadvantage is because they have become expensive.
They are some of the various kinds of inks applied to commercial printing services.
