Printing is a process whereby text and pictures are reproduced on various materials. There are several printing methods and depending on the printing method different types of inks are utilized. Inks utilised in printing might be classified into 4 different categories like aqueous, liquid, paste and powder.
Paste is frequently applied to offset printing and there are a variety of paste inks like cold set, heat set and curable ones. Many of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable provides the highest quality print, heat sets are commonly used. Energy curable ones also require special equipment so that it is probably the most expensive different types of inks utilised in offset printing.
The temperature set one requires heat to create it then it’s cooled rapidly because it catalyses the curing process. In cold set inks, it is set utilizing the phenomenon of absorption in to the stocks which are non-coated. Cold set ones are usually useful for printing books, newspapers, insert printing and so are the least expensive option if you’re with limited funds.
Solvent ink comprises a mixture of organic chemical substances and chemical toxins. These elements have high vapour pressure and colour in this kind of ink is achieved through pigments making them proof against fading. Solvent inks enable you to print on uncoated vinyl substrates and they’re affordable. Banners, billboards, graphics and decals are generally printed using solvent ink. The benefit of using solvent ink for printing is the prints are UV resistant and waterproof nevertheless the issue with employing this is the disposal in the solvent as well as the vapour made by the solvent.
Aqueous inks are primarily applied to desktop inkjet printers. These comprise a variety of pigments or dyes, glycol and water. Aqueous provide the vivid as well as a various colour options the sole problem with this ink could it be just isn’t waterproof and can be washed away from the surface without lamination or specialized coating to shield the ink. Aqueous inks are also inexpensive to manufacture.
UV curable inks:
UV curable inks have acrylic monomers along with an initiator package. As soon as the printing job is finished the printed materials are subjected to strong UV light which cures a lot of it. The main advantage of this ink is it dries quickly and the disadvantage is because they are very expensive.
They’re a number of the different types of inks used for commercial printing services.
