Printing is often a process whereby text and pictures are reproduced on various materials. There are various printing methods and with respect to the printing method different types of inks are used. Inks applied to printing can be classified into 4 different categories like aqueous, liquid, paste and powder.
Paste can often be used for offset printing and you will find different types of paste inks for example 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 finest quality print, heat sets are commonly used. Energy curable ones also require special equipment so that it is one of the most expensive categories of inks used for offset printing.
The heat set one requires heat setting it after which it’s cooled rapidly mainly because it catalyses the curing process. In cold set inks, it is set using the phenomenon of absorption in the stocks which can be non-coated. Cold set ones are generally useful for printing books, newspapers, insert printing and therefore are the most cost effective option if you’re within a strict budget.
Solvent ink comprises a mixture of organic chemical compounds and chemical toxins. These elements have high vapour pressure and colour in this kind of ink is achieved through pigments making them resistant to fading. Solvent inks can be used to print on uncoated vinyl substrates plus they are affordable. Banners, billboards, graphics and decals are usually printed using solvent ink. Lower than replacement using solvent ink for printing is the prints are UV resistant and waterproof though the disadvantage to using this is the disposal in the solvent along with the vapour manufactured by the solvent.
Aqueous inks are primarily applied to desktop inkjet printers. These comprise a combination of pigments or dyes, glycol and water. Aqueous provide you with the vivid as well as a number of colour options the sole drawback to this ink is that it is just not waterproof and can be washed from the surface without lamination or specialized coating to shield the ink. Aqueous inks will also be inexpensive to manufacture.
UV curable inks:
UV curable inks have acrylic monomers as well as an initiator package. Following the printing job is done the printed materials are subjected to strong UV light which cures the ink. Lower than replacement this ink is that it dries quickly along with the disadvantage is they are very expensive.
These are generally some of the various kinds of inks used for commercial printing services.
