What Is the Difference Between Coated and Uncoated Paper? A Complete Guide to Paper Selection for Print Projects
Coated paper is paper substrate treated with a surface layer of clay coating (typically kaolin and calcium carbonate with latex binder) that creates a smooth, sealed surface for enhanced ink holdout and color vibrancy. Uncoated paper lacks this surface treatment, leaving the natural paper fibers exposed, which creates a more porous, textured surface that absorbs ink differently. According to the printing industry as of 2025, understanding the difference between coated and uncoated paper is essential for achieving optimal print quality and selecting the appropriate substrate for specific printing requirements.
