The best file format for a custom LED lightbox design is a vector file. AI (Adobe Illustrator), EPS, or SVG formats are all suitable. If you do not have vector files, a high-resolution PNG with a transparent background at 300dpi at the intended print size is the next best option.
Why Vector Files Work Best
Vector files contain mathematics describing shapes, lines, and text rather than pixels. This means they can be scaled to any size without quality loss. For a custom LED lightbox design that need to be reproduced cleanly at sizes from 30cm table centres up to 1.8-metre standing displays, a vector file format ensures sharp edges and accurate colours at every size.
A raster file, such as a JPEG or low-resolution PNG, contains a fixed number of pixels. Enlarge it and those pixels become visible as blur or blockiness. For photographic images this is sometimes unavoidable, but for logos and text, vector is always preferable.
What If I Only Have a JPEG or PNG
If you only have a JPEG logo, the Boardsy team can assess it. If the resolution is sufficient at the required output size, it may be usable. If not, the team will advise. Common resolutions needed: minimum 150dpi at intended output size for a basic logo; 300dpi for anything involving fine text or detail.
Very low-resolution files, for example a logo extracted from a website at 72dpi at 100 pixels wide, are rarely usable and require recreation from scratch.
What About Fonts
If your design includes text in a specific brand font, supply the font file alongside the artwork or ensure the text is outlined in the vector file. Outlined text converts letterforms to shapes, removing any dependency on font files being installed on the production system.
Colour Specification
Specify Pantone or CMYK colour references if colour accuracy is critical. For RGB displays, the production team will translate your colour references to the appropriate LED calibration.
> “A clean AI or EPS vector file with outlined fonts and specified colours is the fastest route from brief to approved mock-up. The better the input, the faster the output.”
Submit your files via boardsy.co.uk/get-free-mockup/ and the team will confirm suitability before production begins. See the Best LED Lightboxes for Exhibitions and Trade Shows UK 2026.
