Double-Side Coating: C2S stands for Double - Sided Coated. Coating materials are usually minerals such as kaolin and calcium carbonate or special polymers. The coating significantly improves the surface performance of the paper, giving it a smooth and uniform surface. This not only enhances the paper's gloss but also improves its ink absorption and retention capabilities. During printing, it can achieve more precise ink transfer, presenting sharp, vivid prints with rich details, which is suitable for fields with high requirements for printing quality, such as high-end art albums and exquisite posters.
High Gloss and Color Reproduction: Thanks to the high-quality coating, the paper surface has high gloss, which can effectively reflect light, making the colors of printed patterns more bright and full, close to or even surpassing the color performance of the original image. High color reproduction means that when printing color images, photos, or works of art, it can retain the original color information to the greatest extent, making every hue and detail vivid, bringing visual enjoyment to consumers.
Durability: In addition to the physical strength provided by thickness, the coating also enhances the paper's resistance to environmental factors such as water, dust, and dirt. In practical use, it can reduce the damage of external factors to the printed content and extend the service life of the product. When used for outdoor advertising posters, it can resist wind, rain erosion, and dust pollution for a certain period, keeping the picture clear and intact.
Production Process
Raw Material Selection: The main raw material for producing this product is high-quality wood pulp, usually long-fiber wood pulp. Because it has good flexibility and strength, it can endow the paper with excellent physical properties. To ensure the stability of paper quality, the source of raw materials needs to be strictly screened and controlled to ensure product quality from the source.
Pulping Process: Wood pulp undergoes a series of processing steps, including screening, purification, and beating, to remove impurities and adjust the fiber morphology. The beating process is crucial. By precisely controlling the beating degree, the fibers are fibrillated, increasing the bonding force between fibers, thereby improving the strength and uniformity of the paper.
Coating Process: Advanced coating equipment is used to evenly apply the carefully formulated coating material to both sides of the paper. During the coating process, the coating thickness, uniformity, and coating speed must be strictly controlled to ensure coating quality. Common coating methods include blade coating, air knife coating, and curtain coating. Each method has its own characteristics and can be selected according to product requirements.
Drying and Calendering: The coated paper undergoes drying treatment to remove moisture, so that the coating is cured and tightly combined with the paper. Then, calendering is carried out. Through multiple sets of calender rolls, pressure and temperature are applied to the paper to further improve the surface flatness and gloss of the paper, making the paper surface smoother and more delicate.
Quality Inspection: Multiple quality inspection links are set up in the production process. Professional testing equipment and technologies are used to conduct real-time monitoring and analysis of indicators such as paper basis weight, thickness, whiteness, gloss, and ink absorption. Only products that meet strict quality standards in all indicators can enter the market for circulation.
Application Fields
