What are the file requirements for holographic business cards with foil printing?

For holographic and foil business cards, you supply two coordinated files: your main artwork and a separate mask that marks where the special effect goes. The mask tells the press exactly where to lay the foil or holographic finish, so precise alignment between the two files is essential.

• Keep both files the same size with identical alignment.
• Use solid 100% black to define the effect areas on the mask.
• Include proper bleed and keep key content inside the safe area.

For the exact setup of your chosen card, check the product page or contact 4OVER4 support, since options and turnaround can vary by product and may change.
