It is a common and frustrating moment. Your logo looks crisp and clean on your website, so you send the same file off for a banner, a sign or a batch of business cards — and what comes back is soft, jagged and pixelated around the edges. Nothing changed except the size, so what went wrong?
The answer is almost always the type of file, not the logo itself. And once you understand the difference, the fix is simple: get the right file and keep it somewhere safe.
The real reason: pixels versus shapes
There are two fundamentally different kinds of image file, and logos need the right one.
- Raster files (JPG, PNG, GIF) are made of a fixed grid of coloured dots called pixels. Enlarge one and you are not adding detail, you are just making the existing dots bigger — which is exactly what blurring and jagged edges are.
- Vector files (AI, EPS, SVG, vector PDF) store the logo as mathematical shapes and lines. There are no pixels to stretch, so the file can be scaled from a business card to a billboard and stay perfectly sharp at every size.
Your website almost certainly uses a PNG or JPG, because that is what browsers display. That pixel file is fine at small screen sizes and falls apart the moment a printer enlarges it. The logo is not the problem; the file is.
The fix: get your vector files
Somewhere, when your logo was designed, a vector original existed — the designer drew it in vector software. That is the file you need for print, and the one to hand the print shop. If you have it, your blurry-logo problem simply disappears.
If you do not have it, that is the thing to track down. This is exactly why it matters to know which files you should receive with a logo at the point of handover — not two years later when you need a banner.
What you should actually own
A proper logo package includes more than one web image. At minimum you want:
- The vector source (AI or EPS) — the master file.
- An SVG for the web and a vector PDF for print and sending to others.
- PNG files with a transparent background, in a few sizes, for everyday screen use.
- Versions for different backgrounds — full colour, all black, all white — so the logo works on dark and light.
A note on print colour
Two more things trip people up in print. Screens use RGB colour and printers use CMYK, so a colour can shift between the two if the file is not set up for print — a vivid screen blue often prints duller. And if you are forced to use a pixel image, it must be 300 DPI at the final printed size. A vector file sidesteps both problems, which is why print shops ask for it.
If the vector file is truly gone
If nobody can find the original and the designer is long gone, the logo has to be redrawn as a true vector by hand — quick for a simple mark, real work for a detailed one. Avoid automatic "convert to vector" tools; they produce rough, lumpy results that look worse up close.
The lesson for next time is to insist on the full file set at handoff. A logo that works is one you own completely and can use at any size, on anything — which is the standard our logo and branding work is built around. Get the vectors, keep them safe, and the blurry print problem never comes back.
