Uncoated Papers
Paper without a coating to provide a smoother printing surface. Printing on uncoated paper results in the ink spreading (dot gain) more than on the smoother surfaces afforded by coated papers. Images printed on uncoated paper appear duller than on coated papers.

UV Varnish
UV varnish produces a high gloss or matte coating to enhance the finish of a job and protect it from marking. UV varnish is not applied on a conventional printing press and requires a separate process.
