The Ingredients That Are Found In Ink

By Keren Kipfer


Every household in the United States has some use for ink, whether it is an ink pen or an inkjet printer. In addition, businesses use ink every day as well for a variety of important tasks. While ink is highly important, most people don't really know much about how it is made or what it contains, so here are a few interesting facts about ink.

Even when you use the same type of ink, every brand is just a little bit different from another one. However, you typically will find that there are three components found in the majority of all inks, one of which is the colorant. This comes from one of two sources, either a pigment or a dye. The advantages of dyes include the immense range of vivid colors and the cost, which is typically quite a bit lower. On the flip side, dye inks do tend to bleed and run and take longer to dry. They also fade more quickly than pigment-based colorants.

Pigments, on the other hand, are more expensive and have a lower color range. So why would anyone want pigment inks? These pigment inks are more water resistant and also last longer. Pigment inks also dry very quickly, which gives them another advantage. However, improvements in dye ink have made bleeding and fading much less of a problem. Typically, pigment inks are used on slicker surfaces while dyes are used when you want to showcase really vibrant colors.

The binder or vehicle is the second component of ink, and it servers several different functions. The binder provides viscosity which helps the ink flow onto the substrate, which is the object on which the ink is placed. This could be paper, fabric, plastic or some other surface. The binder, typically made from different kinds of resin, also helps get the ink to adhere to whatever you are printing on.

Additives are another component of ink, and while this is all grouped into one single category, there are many different additives used in inks. For example, manganese and cobalt are commonly added as drying agents, and these substances improve the oxidation of ink. Waxes are added to prevent marring. Other substances are adding to improve ink flow and the lubrication. These days soy-based additives often are used because of environmental concerns, but petroleum oils also are still used, as well as other oils.

Ink comes in several different forms, including liquid form, dry or as a paste. Make-up fluids are then added before the inks are used in a printer. If you own an industrial coder, such as a Domino coder, Altima coder or perhaps a VideoJet id printer, you can purchase low-cost, high-quality inks from a product id company that specializes in selling inks, parts and services for those businesses that use id coders.
