How do I setup artwork for Brown Kraft Cards with White Ink?

Brown Kraft cards can include white ink as an overprint, which matters because kraft stock is a natural brown. Printing a white base first gives your colors a bright surface to sit on, so CMYK inks show up vivid and accurate instead of being dulled by the brown paper.

• White as a base: a white layer prints first, then CMYK prints on top
• Brighter color: the white base keeps colors from muddying against the brown kraft
• Set up a white layer: mark which areas need the white underprint in your file
• Or go bare: skip white where you want the natural kraft brown to show through
