Pantone Coated vs Uncoated guides

Customers looking for differences between Pantone Colors specified with Coated or Uncoated suffix and their differences.The terms 'coated' and 'uncoated' are used in the PANTONE PLUS SERIES for printing, and refer to the paper on which the colors are printed.

Coated paper has a shiny gloss coating, and the ink sits atop the coating allowing for minimal ink absorption.  Uncoated paper has no surface coating permitting maximum ink absorption into the paper.   

The same PANTONE color printed on coated and uncoated paper will have quite a different visual appearance.  Although there is a variance in ink film thickness, the majority of the difference is attributed directly to the reaction of the ink to the paper.
