Print setup tips
For plotters or large-format printers, add 3–5 mm bleed and export at 300 dpi or vector/PDF to keep linework crisp. Center-align the artwork to reduce edge risk during trimming or mounting.
Common uses
Exhibition posters
Large visuals for events, trade shows, and storefront backdrops that need maximum area.
CAD and architectural plots
Full-size plan sets for review; keep line weights consistent and export as PDF to avoid scaling errors.
Mounted boards
Foam board or rigid mounts for presentations; leave margin for tape, clips, or frames.
