Review of Related Literature and Studies
Related Literature According to Wikepedia Book, 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 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. 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 ink’s carrier, colorants, and other additives affect the flow and thickness of the ink and its appearance when dry.
Ink formulas vary, but commonly involve four components:
• Colorants
• Vehicles (binders)
• Additives
• Carrier substances
Inks generally fall into four classes:[1]
• Aqueous
• Liquid
• Paste
• Powder
Colorants
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.[1]
Pigments
Main article: Pigment Pigments are solid, opaque particles suspended in ink to provide color.[1] 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.[1] Qualities such as hue, saturation, and lightness vary depending on the source and type of pigment.
Dyes
Main article: Dye Dye-based inks are generally much stronger than pigment-based inks and can produce much more color of a given density per unit of mass. However, because dyes are dissolved in the liquid phase, they have a tendency to soak into paper, making the ink less efficient and potentially allowing the ink to bleed at the edges of an image. To circumvent this problem, dye-based inks are made with solvents that dry rapidly or are
