What file format should I use for aluminum printing?

Aluminum prints large and is often viewed up close, so start with a clean, high-resolution, print-ready file. A properly built PDF gives the most reliable results, keeping type sharp and colors accurate across the metal surface.

• Format: print-ready PDF is the safest choice for signage.
• Resolution: 300 DPI or higher at the final print size.
• Color mode: CMYK for the most accurate color reproduction on aluminum.
• Setup: outline fonts and include the required bleed so nothing is trimmed off.

It is worth having your file reviewed before it goes to press, since many printers will flag setup issues like low resolution or missing bleed before printing.
