Surface Treatment
Base sheets of paper receive a layer of mineral pigments and binders to improve their receptivity to ink and overall smoothness. High quality coated graphic papers facilitate the reproduction of fine detail and intense colors in commercial lithography or digital printing. These materials differ from packaging grades by prioritizing visual appeal and tactile consistency over structural burst strength.
Finishing Variety
Calendaring processes apply pressure and heat to the coated surface to create finishes ranging from dull matte to high gloss. The specific density of the coating on coated graphic papers affects how much ink sits on the surface and how much is absorbed into the fibers. A glossy finish maximizes light reflection and a silk finish reduces glare for better text readability.
Application Range
Magazines and annual reports rely on these substrates to convey a sense of quality through high brightness and opacity. Printers select coated graphic papers based on the grammage and the specific requirements of the binding process. Heavier weights provide the necessary stiffness for covers and lighter options keep postage costs manageable for large mailings.
Because these papers have a closed surface, they require specialized inks that dry through oxidation or ultraviolet curing.
