Getting a sign made from the only logo file you can find

Sign makers and vinyl cutters all ask for vector artwork. How to make it from a small logo file or a photo of the old sign — and what to check at full size.

A sign is the largest your logo will ever be printed, and usually the only file anyone can find is the smallest copy of it that exists. Enlarging that file does not work — a sign maker who is sent a 200-pixel JPG for a three-metre fascia is being asked to guess at every edge, at a size where guesses are visible from across the street.

A blue letter R: on the left a small pixelated copy with fuzzy strokes; on the right a clean vector with straight stems and a smooth bowl.
Left: 170 pixels, JPEG quality 64. Right: Logo mode, two colours. 2 paths, 39 nodes — and every edge is now defined rather than averaged.

Why a vector matters more here than anywhere else

Vinyl cutters and routers follow the outline directly: whatever wobble is in the path ends up cut into the material. Printed signs are enlarged until one pixel of your original is a centimetre of sign. In both cases there is nowhere for a soft edge to hide.

The bowl of the letter magnified: on the left a visible staircase of blue and white pixels; on the right a smooth continuous curve.
Where the bowl meets the stem. Cut this staircase into vinyl and you can see it from the pavement.

If all you have is a photo of the old sign

  • Stand square to the sign, not at an angle — perspective becomes crooked letters
  • Shoot in flat light; a hard shadow across the sign becomes an edge in the trace
  • Fill the frame with the sign alone, and crop the rest away before vectorizing
  • Expect to redraw text: a photographed letterform traces as a shape, and matching the actual typeface will look better than tracing a photograph of it

What the sign maker wants

SVG, EPS or PDF for printed signs. DXF if it is being cut — vinyl, acrylic letters, routed aluminium. Ask which they prefer rather than sending all four, and tell them the finished width in millimetres, because the file itself has no size.

One honest limit worth saying out loud: vectorizing recovers the shape that is in your file. If the only copy of your logo lost a thin outline years ago, it is not in there to recover, and the right answer is to redraw that part rather than to enlarge a guess.
