Engraving can be used to create something special and unique. Engraving sets a higher standard for clients. Because engraving inks are opaque, you can specify PMS coated colors. Ink opacity also allows printing of light (or even white) ink on dark sheets.
You should engrave your design if it includes:
Fine detailed line art
Text with fine serifs
Light colors on dark stock
Image area smaller than 4.25″ x 8.75″
Quality uncoated stock
Single sided image
You should not engrave your design if it includes:
Photographs
Continuous tone images
Solid areas on dark stock larger than .25″
Image area larger than 4.25″ x 8.75″
Coated or varnished paper stock
