Printing tips
Print it right
- Print at 100% / "Actual size". Turn off "Fit to page" so stickers come out the right size.
- Printing a lot? B&W ink saver is the default: black on white, made for any office printer or copy shop. Want a splash of red? Pick Color ink saver.
- Copy shops can print the posters bigger. The codes stay sharp at any size.
- Going outdoors? Laminate posters or use waterproof sticker paper so they survive the rain.
- Test before you post: scan one copy with your phone. It should open qrvirus.world.
Rules of the outbreak
Spread responsibly
- Only post where it's allowed: community boards, your own space, or places where the owner said yes.
- Never cover signs, safety notices, art or other people's posters.
- No vehicles, no public infrastructure, nothing that causes damage.
- Follow your local rules on flyers and stickers.
A good outbreak is one nobody has to clean up.
