There is no universally “best” graphic format. The right choice depends on whether you need an editable master, a placed image, a scalable illustration or a finished delivery file. A reliable workflow keeps the source file intact and creates production derivatives only when required.
| Format | Best use in a print workflow | Watch for |
|---|---|---|
| PSD / PSB | Editable Photoshop master with layers, masks and adjustments | Keep separately; do not treat it as the final press file. |
| TIFF | High-quality placed raster image; supports lossless compression and common print workflows | File size can be large; agree on bit depth and compression if needed. |
| JPEG | Photographs where controlled lossy compression is acceptable | Re-saving repeatedly adds artefacts; inspect at final size. |
| Final page delivery, vector artwork or approved placed PDF | Use the requested PDF/X preset and inspect output. | |
| AI / EPS | Editable Illustrator source or legacy vector exchange | Retain the AI source; EPS is not a default modern delivery format. |
| SVG / PNG / WebP | Web and interface assets | Do not assume they suit a printer’s CMYK or transparency workflow. |
Raster images: preserve the master
For retouching, keep a layered PSD or PSB master. Photoshop’s current guidance also supports TIFF as a flexible format for high-quality raster exchange, while JPEG discards data to reduce file size. A JPEG can print well when it begins with adequate detail and is saved carefully, but compression does not improve an already soft image.
Check effective PPI after placing an image in the layout. For many commercial jobs, 300 ppi at final size is a sound starting point, but final requirements depend on the printing process and viewing distance.
Vector artwork: keep it vector until output
Logos, type and simple illustration are normally best kept as vector artwork. This protects crisp edges at any reasonable scale. Place the approved AI or PDF source into the layout, then export the complete document to a press-ready PDF rather than sending a collection of loosely converted fragments.
Do not confuse web formats with print formats
PNG, GIF, WebP and SVG are excellent tools for web work, but they are not automatically suitable for print. They may use RGB colour, transparency behaviour or compression that needs deliberate handling in a print workflow. Convert only when the printer or PDF workflow requires it, and inspect the final PDF rather than the original asset alone.
Practical handoff checklist
- Keep editable masters separate from placed or delivered files.
- Name versions clearly and avoid repeated JPEG saves.
- Embed or retain profiles according to the agreed workflow.
- Check placed-image scale, effective resolution and links in the layout.
- Export one controlled PDF with the printer’s requested settings.
- Use preflight and output preview before release.
