What file format do I need for holographic business cards?

Holographic cards need your standard print file plus a separate layer that tells the printer exactly where the holographic effect goes.

• Artwork - a high-resolution PDF at 300 DPI in CMYK.
• Foil / holographic mask - a separate layer filled solid black marking where the effect appears.
• Alignment - keep the mask perfectly registered to your artwork.

Check the printer's file-setup guide for the exact mask specifications before you submit, since holographic layers vary by process.
