Ink is used for drawing or writing with a pen, brush, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing. This product is particularly used in inkjet printers.
This product is known as water-based black ink containing porous black carbon nanoparticles with a size distribution of 20-50 nm.
Ink is a liquid or paste that contains pigments or dyes and is used to color a surface to produce an image, text, or design. Ink can be a complex medium, composed of solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescents, and other materials. Pigment inks are used more frequently than dyes because they are more color-fast, but they are also more expensive, less consistent in color, and have less of a color range than dyes. Pigments are solid, opaque particles suspended in ink to provide color. Pigment molecules typically link together in crystalline structures that are 0.1–2 µm in size and comprise 5–30 percent of the ink volume. Qualities such as hue, saturation, and lightness vary depending on the source and type of pigment.In nano-scale, carbon particles are dispersed better in ink than those of bulk matter which leads to better efficiency and quality of printing. Nanostructured inks are highly consistent with the advanced printers including the nozzles with diameter less than 500 nm.
