Quick answer
Send a print-ready PDF at the finished size plus 3mm bleed on every edge, with images at around 300dpi at final size, colours in CMYK, fonts embedded or outlined, and important content kept at least 3mm inside the trim.
The print-ready checklist
- PDF format (PDF/X-1a or PDF/X-4 where possible)
- 3mm bleed on every edge
- Safe area — keep text at least 3mm inside the trim
- Images around 300dpi at final printed size
- CMYK colour (or specified Pantone spot colours)
- Fonts embedded or converted to outlines
- One file with pages in order, unless asked otherwise
What artwork format should I send to a commercial printer?
A high-resolution PDF exported from design software such as Adobe InDesign, Illustrator or Affinity is usually best. Word and PowerPoint files can sometimes be used, but they're more likely to cause layout or colour issues.
Large format is different
Banners and displays are often supplied at a reduced scale with higher effective resolution. Always ask for the template and scale before designing.
