Print-Ready PDF Checklist for Designers
A file that looks perfect on screen can still print wrong: colours shift, edges get clipped, fonts go missing, and a low-resolution image turns to mush at full size. This twenty-point checklist is the pre-flight pass designers run before sending a PDF to print — bleed, colour mode, fonts, images, and proofs, in the order a printer checks them. Use it for flyers, brochures, posters, and anything that will exist on paper.
What’s inside this resource
The checks follow the print pipeline: page setup first, then colour, then type and images, then a final proof. The last five checks are the ones people skip under deadline pressure — and the ones that prevent the most expensive reprints.
The resource (sample)
- Page size matches the printer’s specification exactly.
- Bleed extends 3 mm (or 0.125 in) past the trim on all sides.
- Crop marks are included and sit outside the bleed.
- Colour mode is CMYK, not RGB, throughout the file.
- Spot colours are named consistently and used intentionally.
- All fonts are embedded — no missing-font warnings.
- Body text is at least 7 pt; small print is checked at 100% zoom.
- Images are at least 300 dpi at their printed size.
- No RGB images or elements remain hidden in the file.
- A printed proof has been checked under real light.
How to use this resource
- Run the checklist in order, and do not skip the proof — screen previews hide colour and resolution problems.
- Send the printer the exact file you proofed, not a re-exported “same” version.
- Keep a copy of the approved file with the job name and date for reprints.
- When a check fails, fix it in the source file, not by patching the PDF.
- Ask your printer for their specification sheet first — house rules beat generic ones.
A resource is only useful when it gets used — pick one item today, use it as written, and adapt it from experience rather than from theory.
Frequently asked questions
Why does CMYK matter if my screen shows the colours fine?
Screens use RGB light; printers use CMYK ink. RGB colours outside the CMYK range shift when converted, so designing in CMYK shows you the real result.
What is bleed, in plain terms?
Extra artwork past the cut edge, so trimming never leaves a white sliver. Without bleed, a 1 mm cutting shift shows as a white line.
Is 300 dpi really necessary?
For print at full size, yes. A 72 dpi web image printed large looks soft and pixelated, and no upscaling fixes it.
