Sponsor logos on an event backdrop: why one bad file ruins the wall

A backdrop is printed two metres wide from logos sponsors email at 300 pixels. What to ask for, and where tracing stops helping.

An event backdrop is the least forgiving printed thing most organisers ever order. It is two or three metres wide, photographed all evening, and made of other people’s logos — which arrive by email, at whatever size the sponsor’s marketing assistant had to hand. One 300-pixel PNG in the row is enough to make the whole wall look cheap in every photograph taken in front of it.

Ask first, trace second

Always write to the sponsor and ask for "the vector logo — EPS, AI, PDF or SVG". Larger companies have a brand pack and will send it within the hour. It is free, it is exact, and it carries their approved colour breakdown. Tracing is what you do for the three sponsors who never reply, or who send a logo lifted from their own website because nobody in the office has the original either.

What tracing fixes, and what it does not

It fixes edges. A traced logo has real boundaries, so at two metres the curve is a curve rather than a staircase of squares, and the printer’s RIP has geometry to work with instead of guessing. What it cannot fix is detail that the small copy never contained — a fine tagline under the mark, at 300 pixels, is a grey smear in the source and will be a clean grey smear afterwards.

Colour is a permission question, not a technical one

A trace reproduces the colours in the file you gave it. Those are the colours of a compressed web copy, which are often a shade off the brand’s real values. Where the sponsor has given you a brand guide, set the exact values by hand after tracing. Where they have not, say so on the proof — printing a sponsor’s logo in a colour they did not approve is the one mistake on a backdrop that generates an email the next morning.

Practical rules for the wall

• Build the artwork at a quarter or half of finished size and let the printer scale it — vectors lose nothing, and the file stays workable
• Keep every logo as its own group, so one late replacement does not mean rebuilding the layout
• Leave generous clear space around each mark; sponsors notice crowding faster than they notice anything else
• Keep the lower 40 cm and the top strip clear of anything important — heads and lighting rigs cover them

One last honest point: if a sponsor sends a logo so small that even the shape is ambiguous, the right move is not a better trace. It is a phone call. Nobody has ever been annoyed at being asked for their own logo.
