Do I need to provide a mask file for custom printing effects?

For special effects like spot UV, raised spot UV, or foil, 4OVER4 generally needs a way to show exactly where the effect should appear. This is usually done with a separate layer or mask that marks the effect areas on your artwork.

• Spot UV and raised spot UV: a mask layer marks where the coating goes.
• Foil: a placement file shows where the metallic finish is applied.
• Setup varies by product and effect, so the exact template can differ.

Review the product page file guidelines or ask 4OVER4 support for the exact template and how to supply the mask. Options and turnaround can vary by product, so confirm the latest details before you submit.
