Print-Ready Files: PDF/AI/PSD Requirements and Pitfalls

Step one of online printing is uploading a file. Wrong format, missing fonts and low resolution are the top three rework causes — this checklist helps reduce rework before upload.

Recommended formats, in order

1. PDF (first choice): locked layout, consistent across platforms; export with a print-quality preset
2. AI: vector source — remember to outline fonts (Type → Create Outlines)
3. PSD/TIFF: image-based files; flatten layers, 300dpi, CMYK
4. JPG/PNG: only for purely photographic products, at full source resolution

Pre-upload checklist

• ☐ Size = trim size + 3mm bleed on all sides
• ☐ Fonts outlined (PDF may embed; AI must outline)
• ☐ Images ≥ 300dpi (no blur at 100% zoom)
• ☐ CMYK color (RGB shifts, especially vivid blues/greens)
• ☐ Multi-page files: correct order, page count matches the binding rules
• ☐ Single file ≤ 500MB

FAQ

Q: I only have Word/PPT — can you print it? A: Yes, but "Save as PDF" first — Office files reflow fonts and layout on other machines.

Q: File too big to upload? A: Linyeah Printing accepts single files up to 500MB; beyond that, place the order and attach a cloud-drive link afterwards.

Q: How do I know it's OK after upload? A: The system parses page count and dimensions on upload and flags mismatches against your selected product immediately — no waiting for manual preflight.
