Uncoated paper has not been coated with clay or any other surface sealants. DIfferent to coated paper, uncoated paper drys ins by absorbing it into the paper. Printed paper that are uncoated comprise a large number of paper types and are available in a variety of surfaces; smooth and textured are two. Some uncoated quality sheets contain watermark.
