uncoated

• Non-glare surface• Textured, Roughest -- minimally calendered

– Light scattered– Lowest paper gloss– Lowest printed ink gloss among coateds – Greatest amount of contrast between paper and ink

• Created to replicate look and feel of uncoated• End Uses

– Text, charts– Anywhere to minimize eyestrain– Writeable

• Marks more easily than dull (burnishing)– Pigments have not been compressed as much.

matte finish

25 xMAGNIFICATION

matte finish

• Non-glare surface• Micro-embossed surface, pattern from

rolls imparted by calenders• Excellent ink holdout for sharp halftone

reproduction• Softer images• Richer halftones and solids than mattes

silk/dull finish

25 xMAGNIFICATION

dull finish

• Coating formula and on line calendering technique produce a smooth, low gloss paper

• Looks like a dull -- prints like a gloss• Higher paper gloss than a dull• Similar coat weight to gloss• Smoother, harder surface than a dull• More uniform printing surface than a matte• Offers high level of contrast between paper

and ink film• Distinctive, silky feel• A.K.A. Satin, Suede

satin finish

25 xMAGNIFICATION

satin finish

• Calendered using smooth and polished steel rolls

• Smoothest surface • Highest printed ink gloss

• Highest plain paper gloss of coated finishes -- reflective

• Highest ink hold-out, lowest dot gain

• Best for showing fine detail

gloss finish

25 xMAGNIFICATION

gloss finish

• Brighter the Paper = Brighter the inks

• High Opacity = Heavy ink coverage Two-sided coverage

• Bulk/Stiffness = Dimensional stability Finishing/Bindery

• Surface Uniformity = Smooth ink lay

• Smoothness = Printed ink gloss

printability

• Elegant, sophisticated luxury items• Textured images• Illustrations• Textiles• Haptics

Dull and Silk Finishes

rich, tactile sense

• Text combined with imagery• Soft subject matter• Low-glare requirements• Financials

Silk and Dull Finishes

readability, clarity

• Detail in reproductions• Hard, shiny objects (cars, glassware)• Metallic inks• Solids and screen patterns• Reverse type• Tints and Varnishes

Gloss Finish

fine detail

• Flesh tones• Fine art reproductions• Product/Brand replications• Neutral white shade

Gloss and Dull Finishes

accurate, critical color

• Images rich in warm tones (furniture, food, fabrics)• Earth tones• Illustrations• Neutral and/or cream shades

Dull Finishes

warmth and depth

• Images using blue tones• High-contrast imagery• Hard, shiny, metallic objects• Black-and-white photography• Blue White shade

Gloss Finishes

cool and crisp

• Items handled by consumers• Brand communications• Point-of-purchase material• Inserts• Direct mail• Caliper to weight ratio
