The ink is a liquid containing various pigments or dyes used for coloring a surface in order to create images or text. Although we know that the ink is commonly used in pens or with brushes; however, it is widely used in all sorts of impressions. Currently, inks for writing are all based on chemical dyes, except some manufactured for the particular uses of calligraphy, which can follow traditional recipes. Ink is used in different types of pen, most notably the fountain pen. Whereas, the ballpoint pen ink is originally a typographic printing ink, insoluble in water. The felt pen uses a dye dissolved in a non-aqueous solvent, such as gravure printing inks. Pen ink comes in different colors but mostly in black and blue, although red is also used as well.
