The quality of any printed product must consider the quality of the chosen media. Substrate quality is affected by the primers and overprint varnishes (OPVs). What should you know?

Coated papers being more expensive, we expect higher quality from the printed piece. Gloss coated, which holds the ink high on the surface, will show any defect from inconsistent pre-coating, print head jetting and even inconsistent paper coating.
