Ink is a liquid or paste that contains pigments and/or dyes and is used to color a surface to produce an image, text, or design. Ink is used for drawing and/or writing with a pen, brush, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing. Ink can be a complex medium, composed of solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescers, and other materials. The components of inks serve many purposes; the inkâ€™s carrier, colorants, and other additives control flow and thickness of the ink and its appearance when dry. Ink Jet, like other digital printing technologies, is increasingly becoming a commonly used printing method. The established geographical markets are in advanced industrial countries such as England, Germany, and the United States. However, large emerging markets like Brazil, Russia, India and China are already providing incremental opportunity in terms of acceptance of ink jet technology for various applications including packaging. The new entrepreneurs venture into this industry will be successful due to huge demand of the product.
