Design tips that make a Rectangle stamp look official
- Export as a transparent PNG. A stamp with a white box behind it looks pasted-on the moment it touches letterhead; a transparent one sits cleanly over text and lines.
- Keep ring text short. On round seals, the company or authority name curves around the edge — 40–60 characters reads best. Put registration or licence numbers on the bottom arc.
- Use a light aging texture. A slight fade reads like a genuine inked impression instead of a sticker. The stamp maker has a texture slider for exactly this.
- Classic ink colors read as official. Deep blue and red are the conventions for Rectangle stamps; keep logos monochrome inside the seal.
Make it verifiable — the upgrade rubber can't match
The weakness of every physical Rectangle stamp is that one photographed impression can be copy-pasted onto anything. PDF Verified fixes this with serialization: each application can carry a unique serial number and a QR code that resolves to a public verification page showing who issued the stamp and which document it belongs to. A pasted image fails that scan instantly — which flips the forgery economics of the Rectangle stamp completely.
Is a digital Rectangle stamp legally valid?
In most jurisdictions the signature makes the document binding and the stamp is supporting evidence of authority — and electronic seals are recognised wherever commercial practice expects them (Kenya's KICA, the UAE's Electronic Transactions Law, eIDAS in the EU). A serialized digital Rectangle stamp actually carries more evidential weight than ink, because it comes with a tamper-evident record of when and where it was applied.
