Printing can be a process whereby text and images are reproduced on various materials. There are various printing methods and based on the printing method several types of inks are used. Inks utilised in printing could be classified into 4 different categories like aqueous, liquid, paste and powder.
Paste is usually used for offset printing and you will find different types of paste inks like cold set, heat set and curable ones. A few of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable provides the finest quality print, heat sets are most commonly used. Energy curable ones also require special equipment that makes it one of the most expensive different types of inks utilised in offset printing.
The temperature set one requires heat to put it after which it really is cooled rapidly mainly because it catalyses the curing process. In cold set inks, it really is set using the phenomenon of absorption into the stocks which are non-coated. Cold set ones usually are used for printing books, newspapers, insert printing and so are the most cost effective option in case you are on a tight budget.
Solvent ink comprises a combination of organic chemical substances and chemical toxins. These components have high vapour pressure and colour in this kind of ink is achieved through pigments causing them to be resistant against fading. Solvent inks enable you to print on uncoated vinyl substrates and they are generally economical. Banners, billboards, graphics and decals are normally printed using solvent ink. The benefit of using solvent ink for printing could be that the prints are UV resistant and waterproof however the issue with applying this is the disposal of the solvent along with the vapour produced by the solvent.
Aqueous inks are primarily utilised in desktop inkjet printers. These comprise a mixture of pigments or dyes, glycol and water. Aqueous provide you with the vivid as well as a variety of colour options the one downside of this ink is it isn't waterproof and could be washed outside the surface without lamination or specialized coating to shield the ink. Aqueous inks can also be inexpensive to fabricate.
UV curable inks:
UV curable inks have acrylic monomers coupled with an initiator package. After the printing job is done the printed material is confronted with strong UV light which cures the ink. Lower than replacement this ink is it dries quickly and the disadvantage is because they are incredibly expensive.
These are generally a few of the a variety of inks used in commercial printing services.
