Ball Point Pen Refill Ink

Ink is a liquid or paste containing dyes and pigments, used for writing or drawing by a pen, brush, or quill or for marking a text, design, image, or colored surface. Ink is a gel or solution that contains at least one colorant, such as a dye or pigment, and is used to color a surface to produce an image, text, or design. 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, fluorescents, and other materials.
