Printer inks are inks manufactured especially for printers. The caliber of printing depends on the kind of ink, form of paper and the kind of printer used. The quality of ink is reflected inside the quality of the final product.
Printer ink is made from a combination of dyes or pigments, distilled surfactants, de-ionized water, biocides and fungicides, buffering agents, humectants and resins. These combinations ensure that the ink produced matches the quality specification of OEM ink. Dye or pigment of your particular type and quantity can be used, and also the surfactant helps with balancing the paper wetting and surface tension. Resins ensure paper adhesions and humectants minimize evaporation.
Printer inks are generally dye based or pigment based. Dye based inkjet inks are brighter in color and may produce sharp quality printing. They're stable and can be stored for too long periods of time. One of the drawbacks of dye based inkjet inks is that they are slow in penetrating in most cases take up to ten seconds for drying. Since the drying time is long they often tend to blur. On the other hand pigment inkjet inks are light, fast, waterproof and fade resistant. Additionally they dry faster than the dye based ink and therefore are more fitted to color ink as they prevent blurring. There is also lower toxicity levels than dye-based ink. One of the leading goals of the inkjet ink manufacturers is to develop ink that is durable, fade resistant, and waterproof and it has a chance to print on any media.
