File Preparation Guidelines
Preferred file formats: Data Reproductions Corporation prefers file formats that are print-ready, predictable, and built for color-accurate, production-safe output. Here are the most commonly accepted and recommended formats:
1. PDF/X-4 (Top Choice)
Why it’s preferred:
- Industry standard for print.
- Supports live transparency, layers, and ICC profiles.
- Ensures fonts are embedded.
- Helps prevent color shifts and output surprises.
When to use:
Always, unless we request another standard. PDF/X-4 is the safest, cleanest workflow format today.
2. PDF/X-1a (Older but still accepted)
Why we can still use it:
- Flattens transparency (older RIP-friendly).
- Locks everything into CMYK + spot.
When to use:
If we are running your job on older equipment or specifically requests it.
3. Adobe InDesign Package (.indd + links + fonts)
Why it’s accepted:
- Allows us to make necessary edits (bleeds, color corrections, type fixes).
- Includes all linked images and fonts.
When to use:
If your job needs edits or if we request native files. Not ideal as a final print-ready format.
4. Illustrator Package (.ai + links)
Why it’s accepted:
- Similar benefits as InDesign.
- Useful for vector-heavy work (logos, packaging, labels).
When to use:
If the piece is mostly vector art and may require adjustment.
5. Press-Ready Flattened PDF (High-resolution PDF)
Why it’s accepted:
- Simple, reliable, minimal editing needed.
- Works well for clients who cannot export PDF/X-4.
When to use:
Digital press work, simple one-off prints, or when your design software exports limited print presets.
- Preferred file formats: Data Reproductions Corporation prefers file formats that are print-ready, predictable, and built for color-accurate, production-safe output. Here are the most commonly accepted and recommended formats:
- Resolution requirements
- Bleed & trim info
- Color settings
- Embedding fonts & outlining text
- Image compression guidance
- File naming & organization tips
- Packaging files (InDesign packaging instructions)
- How to supply variable data files
Formats We Do Not Prefer
These are workable, but only if nothing else is available:
Microsoft Publisher (.pub), PowerPoint, Word
Why they’re NOT accepted:
- Not considered “production files.”
- Fonts, image resolution, and color accuracy can be inconsistent.
