Question
What file format should I use for custom sign printing?
Answer
PDF is the most reliable file format for custom sign printing because it locks fonts, colors, and layout exactly as you designed them. Most printers also accept the main vector and raster formats.
| Format | Notes |
|---|---|
| Preferred, most consistent results | |
| AI | Illustrator vector artwork |
| EPS | Vector artwork from most design apps |
| PSD | Layered Photoshop files |
- Outline your fonts before exporting so nothing gets substituted.
- Set the color mode to CMYK for accurate printed color.
- Include bleed and keep key elements inside the safe area.
