The Paper pigments are essential additives used in the paper industry to improve brightness, opacity, and visual quality. They are composed of finely ground inorganic or organic materials that enhance the paper's appearance and functional properties. Titanium dioxide is a widely used pigment due to its excellent brightness, opacity, and light-scattering properties, while calcium carbonate and clay improve smoothness, printability, and bulk. Pigments also help control ink absorption and prevent print-through, ensuring high-quality printed output. They are utilized in a wide range of paper products, including writing paper, printing paper, cardboard, packaging, and specialty papers. Environmental safety is an important consideration, and many modern pigments are non-toxic and environmentally friendly. Paper pigments provide a combination of aesthetic enhancement, functional performance, and regulatory compliance, making them critical for producing high-quality paper products that meet industry and consumer expectations.
