While the Silver or Chrome and Gold metallic options pretty much speak for themselves, how you print your design on them is up for interpretation.  Our proprietary print process allows us to add white ink as a baselayer on the metallic material, then print your art directly over to make a fully opaque color against the metallic material.  We also have the ability to print the colored ink directly on the silver or gold material to create multi-color effets like a metallic green, or rose gold.  We can print with this technique in some areas while printing opaque in others, all on the same design. To submit art in this fashion simply add callouts to your file showing the areas where you would like the art to be opaque, the areas you would like it to be transparent and the areas where you would like to be translucent color.
