Cut lines for acrylic & stickers
Open an illustration, set the finished size in millimetres and get a magenta CutContour line with margin, white plate and a keyring hole or stand base, ready as SVG or PDF for the print shop.
Always check the file against your print shop’s template and spec before you order: sizes, margins and layer names differ from shop to shop.
