Printable Underground Roundel Designs

I’m putting together a set of Halloween outfits and need three authentic-looking London Underground roundels—Metropolitan, Victoria and Elizabeth lines—supplied as print-ready digital artwork. Each roundel must finish at 30 cm wide once printed, so please set the files up at true size with minimum 300 dpi resolution and a transparent or white background.

I’ll be printing them myself and then gluing or taping them onto the costumes, so leave a clean bleed edge and keep colours accurate to the official line branding. PDF and high-quality PNG (or SVG) would be perfect; if you work in Adobe Illustrator or a similar vector tool, please include the original file so I can tweak sizing if needed later.

When bidding, let me know your experience recreating transport or branding graphics and the time you’ll need to deliver the final files. I’m ready to award as soon as I see a strong portfolio match.
