Coated paper and uncoated paper differ in their surface finish and the way they absorb ink. Coated paper has a smooth, glossy finish that is achieved by adding a coating of clay or other substances to the paper surface. This coating makes the paper more resistant to water and ink, resulting in sharper and more vibrant colors. Coated paper is commonly used for printing high-quality images, such as photographs, magazines, packaging boxes, greeting cards and catalogs.
On the other hand, uncoated paper has a rougher, more natural texture and is more porous than coated paper. This makes it more absorbent, allowing it to absorb ink more easily and resulting in a softer, more muted appearance. Uncoated paper is commonly used for printing books, newspapers, and other types of text-heavy documents.
In summary, coated paper is smoother and more resistant to water and ink, making it ideal for printing high-quality images. Uncoated paper has a rougher texture and is more absorbent, making it better suited for printing text-heavy documents.
