A careful proof check can prevent clipped text, awkward cropping, soft images and costly reprints. Use this reusable poster print proofing checklist to review artwork before approving a poster, art print, photo enlargement, exhibition graphic or promotional design.
Overview
A proof is your final opportunity to compare the intended design with the file that will be printed. Whether you are ordering A1 poster printing, a custom size poster, an art print reproduction or a small batch of event posters, do not rely on a quick glance at a thumbnail. Review the artwork at full size, confirm the technical specifications, and check the details that are easy to overlook when concentrating on the overall design.
Start by confirming the printer's current requirements for accepted file formats, maximum upload size, colour-profile guidance, bleed and proof options. These details can vary between products and production systems, so use the instructions shown for the specific order rather than assuming that an older file will meet current requirements. A high-quality PDF is often suitable for poster artwork, but the correct export settings depend on the printer's instructions and the way the file was created.
For general guidance on resolution, bleed, colour and PDF export, see the poster printing file setup guide. If your design was made in Canva, the Canva poster export checklist covers the main print-ready checks.
Checklist by scenario
For a standard poster
- Confirm the finished width and height, including whether the order is portrait or landscape.
- Check that the document size matches the product selected. A1, A2 and A0 files should not be treated as interchangeable.
- Make sure background colours, images and patterns extend through the required bleed area.
- Keep important text, logos and contact details inside the safe margin.
- Read every heading, date, price, web address and call to action at the intended viewing size.
- Check alignment, spacing and consistency between repeated elements.
For a photo poster or personalised print
- Check the crop against the original image, especially around faces, hands, pets and important objects.
- Look for stretched proportions caused by fitting an image into a different aspect ratio.
- Inspect the image at actual print size. A photograph that looks sharp on a phone may appear soft when enlarged.
- Confirm personal names, dates, captions and messages character by character.
- Check that filters, shadows and overlays have not hidden detail or introduced unwanted colour shifts.
For more detail on aspect ratios and image quality, use the photo poster printing guide.
For an art print or reproduction
- Compare the proof with the original artwork or reference image under neutral lighting where possible.
- Check that the full artwork is present and that the border, signature or edition information has not been cropped.
- Review paper and finish choices alongside the proof. Matte and gloss surfaces can affect how colour, texture and reflections are perceived.
- Confirm whether the file includes a border and whether that border is intentional.
- Check that any colour adjustments preserve subtle highlights, shadows and fine details.
If the print is intended for display, you may also want to confirm how the chosen size relates to a mount or frame. The UK poster framing guide can help you check the finished dimensions before ordering.
For a business, event or exhibition poster
- Verify event names, venues, dates, times, ticket information and sponsor names.
- Scan every QR code from the proof or exported file using more than one device if practical.
- Check that the QR code has sufficient clear space around it and is not placed over a busy image.
- Confirm that logos are sharp, correctly coloured and used in the approved arrangement.
- View the poster from a realistic distance to check whether the main message can be understood quickly.
- Confirm quantity, delivery address, required arrival date and any separate versions needed for different locations.

What to double-check
Dimensions, bleed and safe margins
Measure the finished design rather than relying on the file name. A document labelled “A1” may have been resized, and a custom size may have been entered incorrectly. If the artwork runs to the edge, extend it beyond the trim line by the bleed amount specified for the product. Keep text and essential details away from that trim area. This reduces the risk of important content being cut or appearing uncomfortably close to the edge.
Sharpness and effective resolution
Review raster images at their intended output size, not only at 100% on a small screen. Watch for pixelation, blurred edges and compression artefacts. Enlarging a small image cannot create genuine detail. If the artwork contains a mixture of photographs, illustrations and text, check each element separately: a sharp photograph does not compensate for a low-resolution logo.
Colour and paper finish
Colours on screen are produced by light, while printed colours are affected by ink, paper and viewing conditions. Use the printer's colour-profile advice where provided, and avoid approving a print solely because it matches an uncalibrated monitor. Look particularly at dark areas, skin tones, neutral greys and brand colours. Consider whether matte or gloss is more appropriate for the viewing environment; glare can affect a glossy poster, while a matte surface may give a softer visual impression.
Text, fonts and alignment
Run a slow, line-by-line proofread. Check spelling, punctuation, capitalisation, phone numbers, URLs and social handles. Make sure fonts are embedded or converted as required, and confirm that text has not reflowed during export. Compare margins, baselines, headings and image edges. Small alignment errors are often more visible in a simple design than in a busy one.
QR codes and links
Test every QR code after export, not only in the design application. Confirm that it leads to the intended page and that the destination works on a mobile device. Also type out important URLs manually to catch missing characters. A code can be technically present but difficult to scan if it is too small, low-contrast, distorted or surrounded by insufficient clear space.
Common proof problems
| Problem | Likely cause | Action before approval |
|---|---|---|
| Text or logo is clipped | Important content sits too close to the trim edge. | Move it inside the safe margin and re-export the file. |
| Unexpected white border | The artwork and document have different proportions, or the background does not reach the edge. | Confirm the aspect ratio and extend the background or accept a deliberate border. |
| Image looks soft | The source file is too small for the selected print size or has been heavily compressed. | Use a larger original, reduce the output size or replace the image. |
| Colours look dull | Screen and print colour spaces, paper or finish differ. | Follow the supplied colour guidance and check the chosen paper or finish. |
| Font has changed | Fonts were not embedded or available during export. | Embed fonts, convert text where appropriate, and inspect the new PDF. |
| QR code will not scan | It is too small, distorted, low-contrast or obstructed by nearby design elements. | Restore its proportions, increase clear space and test the final file. |
Common mistakes
One frequent mistake is checking only the front page or first version of a design. Compare the exact file uploaded for production, especially if several revisions have been saved. Another is approving a proof while viewing it as a small email attachment. Zooming in is useful for detail, but also view the whole design at a realistic size and distance.
Do not assume that adding bleed will fix every edge problem. Bleed protects backgrounds and images; it should not contain essential text. Similarly, do not treat a PDF export as proof that the artwork is correct. Export can alter transparency, fonts, links, image quality and colour handling, so inspect the exported file rather than the editable document.
Finally, avoid combining approval with last-minute content changes. If a date, price or venue changes after proofing, restart the relevant checks. A small amendment can affect line breaks, alignment, QR codes or the balance of the entire design.
When to revisit
Use this checklist before every order, even when the artwork is based on a previous successful print. Revisit it whenever you change the poster size, image, paper, finish, frame, wording, QR code or delivery details. It is especially useful before seasonal campaigns, exhibitions, product launches and recurring events, when an old file may be duplicated and updated under time pressure.
Printer workflows and upload instructions can change, so check the current product page for accepted formats, upload limits, colour guidance, proof availability and ordering steps before submitting artwork. Keep a final approved PDF, the source file and a short record of the intended size and finish together. That makes future reprints easier to compare and reduces the risk of using an outdated version.
Final sign-off: dimensions confirmed; bleed and margins checked; images sharp enough; colours reviewed; fonts intact; spelling approved; alignment checked; QR codes tested; paper or finish selected; quantity and delivery details confirmed. Only approve the order once every item is complete and the uploaded file matches the version you have signed off.
