In the world of paper, there are two broad categories: uncoated and coated.
Coated paper refers to an offset paper that has been coated with a surface sealant, typically clay, to improve the paper’s brightness, smoothness, and other printing properties.
These papers come in numerous options: Gloss, Matte, Dull or High-Gloss (aka “cast coated”).
So what’s the difference between Matte and Dull?
Matte. A Matte paper is a non-glossy, flat looking sheet. It provides a glare-free, easy-to-read surface. Matte papers are considered the bridge between coated and uncoated paper. They are not super-calendered so they are less expensive and slightly bulkier than Dull coated sheets.
Dull. A Dull coated paper provides a smooth surface with little or no gloss, having a sheen rather than shine. Falling in between Gloss and Matte papers, Dull paper is great for high print definitions and low light reflection.
