An event organiser called us two days before a major trade show. She'd submitted her brand's backdrop artwork to the print shop — a 10-foot wide pull-up banner — and got a call back that the logo was "too low resolution to print."
She was confused. Her logo was a PNG. It was 1,200 pixels wide. That seemed big.
For a 10-foot banner, 1,200 pixels produces a resolution of about 10 pixels per inch. Print quality requires 100–150 PPI minimum for large format. She was short by a factor of 10.
The banner would have printed as an obvious smear.
She needed the logo vectorized in 48 hours so her print shop could proceed. We got it done. The banner looked sharp.
Understanding what large format printing requires — before you're two days out from a deadline — prevents exactly this.
Why Large Format Is Different From Other Printing
Standard commercial printing (business cards, brochures) works at 300 DPI because you hold it 12–18 inches from your face. Pixel density at close range is critical.
Large format prints — banners, billboards, vehicle wraps, trade show backdrops — are viewed from a distance. A 10-foot banner is read from 5–20 feet away. At that distance, you don't need 300 DPI. But you're covering a much larger physical area, so the file needs to cover that area at the correct resolution.
The problem with raster images: resolution is fixed at creation. A 1,200-pixel logo is 1,200 pixels, period. If you need to print it at 10 feet wide, those 1,200 pixels have to cover 10 feet. The result is blurry.
Vector files have no resolution. They're mathematical descriptions of shapes. Scale a vector logo to 10 feet, 100 feet, or 1,000 feet — it's always calculated fresh at the output size. This is why large format printers require vector files for logos.
Minimum File Requirements for Large Format
For the logo itself: vector is non-negotiable
Your logo must be a vector file — AI, EPS, or SVG. Not a PNG, not a JPEG, not a "high-resolution" JPEG at 300 DPI (which is still raster).
If your logo is "vector" but contains embedded raster images inside the vector container, it will fail at large sizes. See our post on checking whether your logo is truly vector before submitting any file.
The vector file must have all text converted to outlines. Live text requires the font to be installed on the printer's computer — if they don't have your font, the text reflows with a substitute. Outlined text is pure shapes and is safe on any system.
For the full artwork file (layout with logo):
The full design layout — background, additional text, images — is usually built as a raster file at reduced DPI. Large format print shops accept different specs depending on the print size:
- Up to 6 feet: 100–150 PPI at actual print size
- 6–20 feet: 75–100 PPI at actual print size
- Billboards and large outdoor: 25–50 PPI at actual print size
If your print shop asks for the file at 25% scale, that means you build at 25% of the final size at 100 DPI — which is equivalent to 25 PPI at full size. This is their standard way of managing workable file sizes.
The logo should be placed as a linked vector file within this layout — not rasterized into the layout at a lower resolution.
Colour mode
Large format printing is CMYK. Submit all files in CMYK, not RGB. RGB colours shift when converted to CMYK at the printer — blues often shift purple, vibrant greens go dull, and screen-bright oranges become muted. Convert to CMYK yourself and verify the colours before submitting.
If you have Pantone spot colours, provide both the Pantone value and its CMYK conversion. Some large format processes can't print true Pantone (they use CMYK approximations), so understanding what the CMYK equivalent looks like prevents colour surprises.
Our guide on why logos look different when printed goes deeper into colour mode issues if you've experienced colour shifts at the printer.
Common Large Format Sizes and Their Requirements
| Format | Common Size | Viewing Distance | Notes |
|---|---|---|---|
| Pull-up banner | 33" × 80" | 3–10 ft | Vector logo, 100 PPI layout |
| Trade show backdrop | 8–20 ft wide | 5–20 ft | Vector logo, 75 PPI layout |
| Vinyl banner | Custom | 5–30 ft | Vector logo, 75–100 PPI |
| Billboard | 14 × 48 ft | 100+ ft | Vector logo, 10–25 PPI |
| Window graphic | Custom | 1–10 ft | Vector logo, 100 PPI |
| Vehicle wrap | Full vehicle | 5–50 ft | Vector logo, 75–100 PPI at scale |
Bleed, Safe Zone, and File Setup
Large format prints require:
Bleed: Extra artwork extending beyond the finished edge — typically 0.5–1 inch on each side. This prevents white edges when the material is cut. Extend your background colour and any edge elements into the bleed zone.
Safe zone: Keep all text and logos at least 1 inch from the finished edge. This ensures content stays visible even if trimming is slightly off. Keep your logo further from the edge than you think you need to — 2–3 inches on large formats looks better and has more safety margin.
File size: Large format artwork files can be enormous — 1 GB or more for billboard artwork. Most print shops have an FTP or WeTransfer link for large file submissions. Don't email artwork.
What to Send Your Printer
A complete print submission for a banner or trade show backdrop typically includes:
- AI or EPS layout file with logo as vector, fonts outlined, CMYK colours
- PDF proof at actual size (or at a stated scale like 1:10) for sign-off
- Colour callouts — note exact HEX or Pantone values for critical brand colours so the operator can verify output
- Logo file separately — send the standalone logo file in case they need to place it themselves
If your logo needs to go from raster to vector before you can submit, our vectorization service delivers print-ready files within 24–48 hours. That's faster than most large format print deadlines allow for reprints.
Get Your Logo Banner-Ready
We vectorize and prepare logos for large format printing — clean paths, outlined text, correct colour mode. Ready for any print shop.
Raster images (JPEG, PNG) have a fixed number of pixels. Scaling them to banner or billboard sizes spreads those pixels across a large area, producing visible blur. Vector files are mathematical paths with no resolution limit — they render sharply at any size.
For pull-up banners viewed at 3–10 feet, 100–150 PPI at actual print size is standard. For large trade show backdrops (8+ feet), 75–100 PPI is sufficient. Billboards viewed from 100+ feet need only 10–25 PPI. The logo within the layout should always be a vector placed as a link — not rasterized.
300 DPI at what size? A 300 DPI, 4-inch PNG is 1,200 pixels wide. That's 10 pixels per inch at 10-foot print width — far too low. Resolution is meaningless without knowing the file dimensions. Only a vector file is guaranteed to be sufficient at any print size.
Bleed is extra artwork extending beyond the finished cut edge — typically 0.5–1 inch on each side. It ensures that when the banner is trimmed to size, there are no white gaps at the edges even if cutting is slightly off. Always include bleed on banners and signage.
RGB blues often shift purple in CMYK conversion because the gamut is different. You should convert to CMYK yourself in Illustrator (File > Document Color Mode > CMYK) and adjust the colour values until the CMYK output matches your brand colour as closely as possible. Then submit the CMYK file.
Yes, PDF is widely accepted. Use PDF/X-1a or PDF/X-4 preset when exporting — these flatten transparency and embed fonts, which prevents rendering issues. Make sure the PDF is exported in CMYK and includes bleed marks.
Quick Answers
My banner printed blurry. The printer said the logo file was too low resolution. What should I do?
You need a vector version of your logo. Vectorization rebuilds the logo as scalable paths — no resolution limit. Once you have the vector file, send it to the printer and request a reprint.
How big a file do I need for a 10-foot banner?
At 100 PPI, a 10-foot (120-inch) banner needs an image 12,000 pixels wide. At 75 PPI it's 9,000 pixels. Your logo within it should be a placed vector, not a rasterized element.
The print shop said my fonts need to be outlined. What does that mean?
Outlining fonts converts text to shapes (paths). The printer's computer then doesn't need your font installed — it just renders the shapes. In Illustrator: select all text, then Type > Create Outlines.
I have an SVG logo. Will that work for large format printing?
Most large format print shops prefer AI or EPS over SVG. SVG is technically the same underlying format but some print RIP software handles it less reliably. Export an AI or EPS from Illustrator using the SVG source.
Can I use my logo on a billboard without changes?
If it's a true vector file in CMYK, yes — vector scales to any size without quality loss. If it's a raster file at any resolution, no — billboards are enormous and even a 'large' raster file will look pixelated.
