Quality documents get compared line by line, so a plain, consistent letterhead with a clear signatory line matters more here than colour or decoration.
What a quality letterhead should show
- “Quality Control” or “Quality Assurance Department” in the header
- Accreditation or certification number, if applicable (ISO, etc.)
- Inspector or QA signatory with a signature line in the footer
- Company name, logo and registered address
Where it is used
- Inspection and testing reports
- Non-conformance and corrective-action notices
- Quality certificates attached to a shipment or batch
Keep the layout plain and the signature line prominent — inspection reports are read for accuracy, not decoration.

Frequently asked questions
Can I add an ISO or certification number?
Yes — enter it in the registration field and it appears wherever the design shows registration details.
