Field notes

The editor uses preset categories and constrained controls rather than a freeform drag-and-drop canvas, keeping stamp text centered and legible. Its examples include a 38 mm circular design, company and notary layouts, deposit-only endorsements, date marks, and Chinese name seals. Export guidance distinguishes a transparent 6000px PNG for digital placement, outlined SVG paths for physical manufacture, and a PDF described as raster content placed at the stamp’s true physical size.
