How is coated duplex board paper different from regular duplex board paper?

Coated duplex board paper differs from regular duplex board paper in terms of its surface characteristics and printing capabilities. Here are the main differences:

1.Surface Coating: Coated duplex board paper has a layer of coating applied to one or both sides of the board, while regular duplex board paper typically lacks this coating. The coating is typically made of clay or other materials and serves to enhance the smoothness, brightness, and printability of the paper.

2.Print Quality: The coating on coated duplex board paper allows for better ink holdout, resulting in sharper and more vibrant printed images. It provides a smoother surface for printing, which can result in finer details and improved color reproduction compared to regular duplex board paper.

3.Surface Smoothness: Coated duplex board paper generally has a smoother surface texture due to the coating layer. This smoothness contributes to better print quality and enhances the appearance of the final printed product. In contrast, regular duplex board paper may have a slightly rougher surface texture.

4.Finish Options: The coating on coated duplex board paper provides options for different finishes, such as gloss, matte, or satin. These finishes can be chosen based on the desired aesthetic appeal or functional requirements of the final product. Regular duplex board paper typically does not offer such finish options.

5.Printability: Coated duplex board paper offers improved printability, as the coating helps prevent ink from being absorbed into the paper fibers, resulting in less ink spread and sharper images. It also allows for better control of dot gain, which is the increase in the size of printed dots due to ink absorption. Regular duplex board paper may have lower print quality and limited control over dot gain.

6.Application Range: Coated duplex board paper is often used for applications that require high-quality printing, such as packaging boxes for consumer goods, cosmetics, pharmaceuticals, and promotional materials. Regular duplex board paper, with its lower print quality, is more commonly used for applications where printing quality is not a primary concern, such as backing boards, partitions, or secondary packaging.
