Printing can be a process whereby text and images are reproduced on various materials. There are several printing methods and depending on the printing method different types of inks are widely-used. Inks used in printing may be classified into 4 different categories like aqueous, liquid, paste and powder.
Paste can often be used in offset printing and there are a variety of paste inks such as cold set, heat set as well as energy curable ones. A number of the different energy curable sorts are electron beam curable and ultraviolet curable. While energy curable provides the top quality print, heat sets are used. Energy curable ones also require special equipment so that it is probably the most expensive types of inks utilised in offset printing.
The heat set one requires heat to put it and then it is cooled rapidly because it catalyses the curing process. In cold set inks, it is set with the phenomenon of absorption into the stocks which can be non-coated. Cold set ones are often employed for printing books, newspapers, insert printing and they are the most affordable option in case you are on a tight budget.
Solvent ink comprises a variety of organic chemical substances and chemical toxins. These elements have high vapour pressure and colour in this type of ink is achieved through pigments causing them to be resistance against fading. Solvent inks may be used 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 is that the prints are UV resistant and waterproof even so the disadvantage to applying this will be the disposal in the solvent and also the vapour created by the solvent.
Aqueous inks are primarily applied to desktop inkjet printers. These comprise a combination of pigments or dyes, glycol and water. Aqueous offer the vivid and a number of colour options the sole disadvantage of this ink could it be is just not waterproof and could be washed from the surface without lamination or specialized coating to shield some of it. Aqueous inks will also be inexpensive to fabricate.
UV curable inks:
UV curable inks have acrylic monomers as well as an initiator package. Following your printing job is finished the printed materials are encountered with strong UV light which cures some of it. Lower than replacement this ink is it dries quickly as well as the disadvantage is they are incredibly expensive.
They're many of the different types of inks used in commercial printing services.
