There is no single correct bleed amount, color profile or PDF preset for every job. This guide walks through the decisions to confirm and the checks to make before delivery.
Get the print provider’s specifications
Ask the receiving print shop for its required output settings before finalizing the file. Request the accepted PDF standard or preset, color profile or output condition, bleed amount, whether printer’s marks are needed, and any supplied .joboptions file. Also confirm whether the job uses process or spot inks and whether the shop handles trapping. Adobe advises consulting the print provider about output settings and working closely with it on separations: Adobe Illustrator printing guidance and Adobe separations guidance.

Set up color for the intended output
Use color management for the actual printing condition rather than converting artwork to a generic CMYK profile by default. Adobe’s preparation guidance includes monitor calibration and an Illustrator color setting; the printer’s specified profile and conversion instructions should determine the final setup. Check the document’s color mode and confirm which application or production stage is responsible for conversion.

Process-color printing separates artwork into cyan, magenta, yellow and black plates. Spot colors use custom inks, with each spot ink producing its own plate. Spot color is therefore a production choice as well as a color choice; confirm that the shop supports the required ink and plates. For color-managed spot workflows, Adobe recommends Lab values when the correct device profiles are in use. See Adobe’s separations documentation and Adobe’s spot-color guidance.
#1 Best Overall
When specifying a process color, a printed CMYK reference chart can help communicate the intended color. A chart is a reference, not a guarantee that the printed job will match exactly; the final appearance depends on the printing condition.
Extend artwork through the bleed area
Bleed is artwork that extends beyond the trim boundary. It gives the trimming process room for slight variation so background color or imagery can reach the finished edge without leaving an unprinted sliver. Extend any edge-touching artwork to the bleed boundary specified by the print provider; do not assume a universal measurement.
Rank #2
When saving the PDF, use the document’s bleed settings or enter the values the provider requested in the PDF’s Marks and Bleeds settings. Printer’s marks are separate from bleed: include them only if the provider asks for them. Adobe explains bleed and PDF marks and bleed controls in its printing marks and bleed instructions.
Inspect plates, transparency and overprinting
Use Illustrator’s Separations Preview to inspect process and spot-color plates and to check effects involving rich black, transparency and overprinting. The preview is diagnostic: hiding a plate on screen does not remove it from the exported output. Adobe recommends coordinating with the shop before and during separations work in its separations guidance.
Understand what overprint changes
In a knockout, an upper object removes the underlying color in its area. Overprinting instead lets inks overlap, so the top ink can appear transparent in relation to the ink below it. This may help avoid gaps caused by plate-registration variation; trapping uses a small overlap for the same general production problem. But overprinting also changes the way colors combine, and the result depends on ink, paper and printing method. Confirm the intended treatment with the print provider and inspect a proof for critical work. Adobe explains these effects in its overprinting documentation.
Choose the PDF standard the receiving workflow accepts
PDF/X is a family of standards for exchanging print-ready graphic content. Adobe distinguishes the workflows this way:
| Standard | Workflow characteristic |
|---|---|
| PDF/X-1a | Designed for a CMYK workflow. |
| PDF/X-3 | Supports a color-managed workflow. |
| PDF/X-4 | Supports a color-managed workflow and preserves live transparency. |
Adobe recommends PDF/X-4:2008 for reliable print-publishing workflows, but the provider’s accepted standard takes precedence. PDF/X-1a files require embedded fonts, appropriate marks and bleed, CMYK and/or spot colors, and information about the intended printing condition. Adobe’s overview of PDF options and standards is available at Adobe’s guide to creating PDFs.

Check export settings before saving
In Illustrator’s PDF options, verify the requested standard or compatibility, Marks and Bleeds, output conversion and destination profile, and any advanced font, overprint and transparency settings required for the job. PDF/X files also require an output intent, which identifies the intended printing condition. If the shop supplies a .joboptions file, use its instructions rather than substituting a generic preset. Adobe notes that appropriate PDF settings depend on the standard, color-management state and destination; see its PDF creation guidance.
Deliver typography and source files appropriately
A print-ready PDF is generally the most reliable way to preserve typography in the handoff. Do not assume you can send font files: permission depends on the font’s license, and Adobe Fonts terms do not permit copying or moving its font files. If the printer needs an editable Illustrator package, verify the applicable font license and ask whether the shop already has access to the required fonts. See Adobe’s font packaging guidance.
Quick Recap
Final preflight before delivery
- Confirm the job spec: obtain the provider’s PDF standard or preset, output condition, bleed, marks, ink requirements and trapping instructions.
- Check color: confirm the document mode and color-management responsibility, and verify that spot inks are intentional.
- Check page edges: extend edge artwork to the specified bleed and use marks only as requested.
- Preview production behavior: inspect separations, transparency and overprint; ask the shop about trapping and proof critical output.
- Export and verify: apply the accepted PDF settings, confirm the output intent when using PDF/X, and deliver the PDF plus any permitted editable files the printer requested.
