The Science of Printing Ink: Understanding the Building Blocks

Printing ink is an essential material in the printing industry, used to enhance the quality level of decoration and packaging. It adds color, detail, and appeal to packaging surfaces. Over the years, the demand for high-quality packaging has significantly increased, and the printing industry has responded by improving the quality of plastic and paper packaging.

Currently, in the international market, most inks are composed of ink binders (Printing ink resins), ink pigments, ink additives, and organic solvents. The binder, comprising 20% to 40% of the ink, is an adhesive resin that binds the pigment and the printed material together, creating an adhesive effect and a shiny appearance. The pigment, comprising 5% to 15% of the ink, determines the ink's color. The organic solvent, comprising 40% to 60% of the ink, dissolves the resin, adjusts the viscosity and drying speed, and improves the wetting effect on the printing material. Finally, the additives, comprising 0% to 5% of the ink, play a role in improving viscosity, weather resistance, aging resistance, and increasing gloss.
