Do I need to select a foil color for Holographic Postcards to get the holographic effect?

No. The holographic, rainbow-shimmer effect is built into Holographic Postcards by default, so there is no separate foil color to select.

• The holographic layer covers the stock automatically as part of the product.
• You do not pick a foil color the way you would for a stamped foil accent.
• Your artwork prints over the holographic base, and the shimmer shows through the lighter and unprinted areas of your design.
