Coated black and white paper

Coated black and white paper is a process where a white coating layer is applied to the surface of the paper, followed by partial printing of black patterns. The principle involves using the coating to conceal the original paper and create a printing substrate, with black patterns being displayed through ink adsorption. Its function is to provide background contrast for packaging and labels. It is used in applications such as food packaging and industrial labels that require high opacity.
Selection
When selecting, consider the matching between the base paper grammage and coating thickness, and observe coating uniformity to avoid substrate exposure. Determine the required black-and-white contrast based on the intended use, and check the printing clarity of black patterns. Test paper stiffness and printability to match the parameters of subsequent processing equipment. Verify the coating's resistance to peeling to ensure stability during storage and transportation.
