The Paper pigments are coloring and whitening agents used to enhance the appearance, quality, and performance of paper products. They are added during the paper manufacturing process to improve brightness, opacity, smoothness, and printability. Common pigments include titanium dioxide, calcium carbonate, clay, and various organic colorants. Titanium dioxide, for instance, is known for its high brightness and opacity, making it ideal for premium printing papers. Paper pigments also help prevent ink from bleeding or smudging and enhance color reproduction for vibrant printed materials. Beyond visual enhancement, pigments contribute to functional properties, including mechanical strength, surface smoothness, and durability. The development of eco-friendly, non-toxic pigments has enabled their use in food packaging and environmentally conscious applications. They are widely used in writing paper, printing paper, cardboard, specialty papers, and packaging materials, ensuring consistent quality and aesthetics. With the growing demand for high-performance and visually appealing paper, pigments have become indispensable in modern paper production.
