Your logo is the face of your business. When it appears on your packaging, it needs to look immaculate. But moving your logo from your website or business card to a cardboard box isn't straightforward. Different formats, colour systems, sizing rules, and technical requirements can trip you up if you're not prepared.
Many brand owners approach this blindly and end up with logos that look fuzzy, colours that don't match their brand guidelines, or designs that don't fit properly on the box. Then comes the frustration of reprinting, the cost of wastage, and the brand inconsistency that customers notice.
This guide walks you through exactly how to prepare your logo for packaging boxes. You'll learn which file formats matter, how colour systems work, where to place your logo for maximum impact, and how to communicate clearly with your supplier so nothing goes wrong. Whether you're designing internally or working with a graphic designer, this gives you the knowledge to get it right first time.
Your logo probably exists as a JPEG or PNG on your website. These formats look perfect on screens but fall apart when printed on cardboard.
A JPEG or PNG is a raster file. It’s made of pixels, tiny coloured squares arranged in a grid. This works brilliantly for photographs and complex images. Zoom in on a JPEG, though, and the pixels become visible. The edges get blurry. Print that same image at large size, and it looks terrible.
A vector file, by contrast, is built on mathematical equations. Instead of pixels, it uses lines, curves, and shapes defined by coordinates. Zoom in infinitely, and a vector graphic stays perfectly sharp. This is why vector files are the professional standard for logos, which need to work at every size from a postage stamp to a billboard.
For packaging, you should have your logo in one of these vector formats:
Adobe Illustrator (AI): This is the gold standard. Illustrator is specifically designed for creating and editing logos and vector graphics. If you’re working with a designer, ask them to provide the Illustrator file (or the project file from their chosen vector software).
EPS (Encapsulated PostScript): EPS is an older but still widely used vector format. It’s compatible across platforms and is universally understood by printers and print-focused software. If your designer doesn’t have Illustrator, EPS is the next-best option.
PDF (Portable Document Format): PDFs can contain vector information, though they’re often used for final delivery rather than editable source files. For packaging, a vector PDF is acceptable, though a true vector file is preferable.
SVG (Scalable Vector Graphics): This is becoming more common, especially in digital-first workflows. SVG is perfect for vector information and widely supported, though not all traditional printers are equally familiar with it. Check with your packaging supplier.
What you don’t want: JPEG, PNG, GIF, or BMP for your logo on packaging. These are raster formats and will not print crisply.
If your logo only exists as a JPEG or PNG, you have options, but none are ideal. You can trace it in vector software (creating a new vector version based on the raster). This works well for simple, solid-colour logos. For complex, photorealistic logos, it’s harder.
Many graphic designers can trace logos for reasonable cost (typically £30 to £80 depending on complexity). This is worth doing if your logo is the face of your business. Alternatively, talk to your packaging supplier. Some have designers in-house who can help, though they’ll charge for the work.
Going forward, always keep a vector version of your logo. It’s a business asset you’ll need for packaging, signage, embroidery, merchandise, and more.
Colours look different depending on how they’re created. Your screen shows colours using RGB (Red, Green, Blue light). Print uses CMYK (Cyan, Magenta, Yellow, Black ink). They’re fundamentally different systems, and the mismatch causes endless confusion.
Print uses CMYK because those four colours, in different proportions, create every other colour the eye can see. When you print on cardboard, the press applies separate layers of cyan, magenta, yellow, and black ink. The overlapping creates the full spectrum.
RGB colours, which exist only on screens, can’t be directly printed. They need converting to CMYK first. And here’s the gotcha: the RGB red you see on your monitor might convert to a CMYK red that looks noticeably different when printed. Reds get darker, oranges shift, and blues sometimes appear purple. Blues are especially problematic.
This is why you must prepare your logo in CMYK, not RGB. If your designer used RGB, ask them to convert it to CMYK. In Adobe Illustrator, this is as simple as Image > Mode > CMYK. In other software, it might be Export > CMYK.
If your logo has specific brand colours that must be exact, you need Pantone numbers. Pantone is a universal colour system where every shade has a unique number. Pantone 185 is always the same red, whether printed in the UK, USA, or Japan.
Your brand guidelines probably mention Pantone colours. For example, Boxtopia’s branding might reference a specific Pantone for their primary colour. When you specify Pantone numbers, your printer can match them precisely using spot inks or by adjusting their CMYK values.
Ask your designer for Pantone numbers for your logo colours. If they don’t have them, get a Pantone guide (available online or in physical books) and find the closest match to your colours. Your printer then uses these numbers as the source of truth.
For packaging boxes, there’s a nuance: if your design is full-colour (photographic or complex gradients), Pantone isn’t practical. You’ll use CMYK process colours instead. But if your logo is solid colours (which most logos are), Pantone ensures consistency.
Before sending your files to the printer:
A logo that’s the right size on a business card is far too small on a cardboard box. Sizing for packaging requires thinking about distance and visibility.
Your logo should be visible and recognisable from at least a metre away when someone’s holding the box. This means it needs to be substantially larger than on digital or paper marketing collateral.
For a mailing box (roughly A4 size), a logo should typically be at least 5 to 7 centimetres wide. For larger boxes, go bigger. For smaller boxes, adjust proportionally.
Test by printing a mock-up at actual size and viewing it from arm’s length. Does the logo immediately stand out? Can someone identify your brand instantly? If yes, you’ve nailed the size. If you’re squinting, it’s too small.
The front (main surface) of the mailing box is prime real estate. This is what someone sees when the package arrives. Place your logo prominently here, usually in the top corner or centre.
Avoid the very edge of the box. During cutting and folding, the registration (alignment) can shift slightly. Keep your logo at least 1cm away from any edges. Your printer will tell you the exact safe zone.
Consider how the box folds. The flaps at the top and bottom have less prominent placement, but logos there are still visible and can reinforce branding. Some brands use a small secondary logo on the bottom, knowing that’s visible during unpacking.
Balance your design. If your logo is huge and unbalanced, the box looks amateur. Equally, if it’s tiny, it’s invisible. The goal is prominent but not overwrought.
Often, you’ll add text alongside your logo: your company name, website, social media handles, or a tagline. This should be sizeable enough to read from a reasonable distance. Minimum font size for packaging is typically 6 to 8 points, but 10 to 12 points is more readable.
Contrast matters. Light text on dark cardboard is readable. Dark text on light cardboard is readable. But light text on light cardboard or dark text on dark cardboard is illegible. Check your contrast.
Colours are where things often go wrong. Your brand colour looks perfect on your laptop but different on the printed box. Understanding why helps you prevent this.
Brown kraft cardboard is the default for many boxes. Any colour printed on it is influenced by the brown base. A yellow logo on kraft looks greenish compared to yellow on white cardboard. Reds look darker, blues look muddier.
If your brand colours are critical, specify the cardboard grade. White cardboard gives the truest colour representation. Fluting (the wavy layer inside) is usually brown, so even white-lined boxes have some brown influence from the sides.
Before committing to full production, request a physical colour swatch or proof showing your logo on the cardboard grade you’ve chosen. Digital previews are deceptive because your monitor displays colours differently than print.
Most printers charge a small fee for colour proofs (£20 to £50), but it’s worthwhile insurance. You see the actual ink on actual cardboard under actual light. This reveals unexpected shifts that digital previews miss.
If you’ve specified Pantone colours, the printer will do their best to match them using the available inks. In some cases, especially with metallic or fluorescent Pantones, exact matches are technically impossible. Discuss what’s achievable with your printer.
Process colours (CMYK) can’t perfectly match every Pantone, but they come close. Your printer might provide a bridge showing how your Pantone translates to CMYK.
The amount of ink applied affects colour. Solid, full coverage (100% ink) looks richer than a screen or tint (say, 50% ink). If your logo includes both solid areas and screened areas, specify these in your design.
A spot varnish (a clear glossy or matte coating) can be applied over your logo to make it stand out and protect it. This adds cost but significantly enhances the premium feel of packaging.
If you’re working with a graphic designer, clear communication prevents rework.
Explain that this is for packaging, not digital use. Give them your logo, brand guidelines, and the box dimensions. Ask them to design in CMYK and to provide vector files.
Mention any constraints: your logo must stay a certain distance from the box edges, it needs to work on kraft cardboard, it should include your website or social handles.
Request a proof or mockup showing the design on the box. This helps spot issues before production.
When you send files to your printer, include a brief specifications document:
Ask them to check your files for issues and request a digital or physical proof. Confirm their preferred file format and colour mode.
Be explicit: “My logo must be exactly as specified in the Pantone guide” or “Slight colour variation is acceptable” depending on your tolerance.
Once your printer has produced a proof, review it carefully.
If anything’s not right, communicate this clearly. Don’t say “the colour’s a bit off” – be specific: “the blue appears more purple than expected” or “the logo is too small and hard to read from a distance.”
Your printer will either adjust and provide a new proof or explain what’s not feasible. This back-and-forth is normal and important.
Solution: Always provide vector files. If you don’t have them, ask your designer to create them or arrange for your logo to be traced into vector format.
Solution: Before sending files, ensure they’re in CMYK colour mode. Ask your printer what colour mode they prefer.
Solution: Test sizing on a full-size mockup. Can you read and recognise your brand from a metre away?
Solution: Request a physical proof on your chosen cardboard. This reveals colour shifts that digital previews hide.
Solution: If colour accuracy matters, provide Pantone numbers. Your designer should have these in your brand guidelines.
Adding your logo to packaging boxes is a technical process, but it’s straightforward once you understand the fundamentals. Prepare vector files in CMYK, specify Pantone colours if precision matters, size your logo for visibility from a distance, and place it with breathing room from edges.
Work with a printer who reviews your files before production and provides proofs. Communicate clearly about what you want and why. Don’t skip the proof stage; that’s where problems surface and get fixed.
