The quality of an inkjet printing is very much influenced by the physico-chemical properties of printing ink. Here lies the importance of inkjet dyes. Dyes for Inkjet ink are a bit different from the usual dyes that are available for fibers. This is because of the fact that they need to have high purity, and do contain small salt and inorganic matters. Dye inks are prepared by dissolving of the liquid colored dyes into a fluid carrier. This makes the dyes easy to apply. When it is applied to a paper, the dyes are absorbed very uniformly so they reflect light very evenly. As the printing is a high precision job the inkjet dyes need to have superior quality in terms of colors, physical properties, and stability. Generally direct, reactive, and acid dyes are used as dyes for Inkjet Ink. Inkjet dyes can also come in the form of powders besides the usual liquids.
