Bad artwork is the #1 cause of reprints and delays. A file that looks perfect on screen can print with dull colour, blurry text or a white edge. This guide sets the specs that pass first time at a commercial printer.
Spec checklist

| Resolution | 300 dpi | 72 dpi |

Choose your format
| Format | Use when |

| IDML | InDesign exchange |
Expert tips
- Convert to CMYK before export. RGB blues and greens shift on press; convert early to preview true colour.
- Add 3 mm bleed, not 0. Any element touching the edge needs bleed or you get a white strip.
- Outline your fonts. Embedded fonts occasionally fail; outlined text never does.
- Embed ICC profile. We print to GRACoL / FOGRA so colour matches your proof.
Four-step handoff
- Build at 300 dpi in CMYK with 3 mm bleed.
- Outline fonts and embed the ICC profile (GRACoL / FOGRA).
- Export PDF/X-4; keep the AI/EPS source as backup.
