About this seal
SPECIMEN has long been the word printed across sample cheques, certificates and signature cards to show they are examples with no value. Banks, printers and certificate issuers use it on proofs so a design can be shared without creating a usable document.
Common uses
- Sample cheques and payment forms
- Certificate and diploma proofs
- Signature specimen cards
- Printed stationery proofs
How to create it
- Open the template — the red diagonal overlay stamp reading “SPECIMEN” is pre-applied.
- Edit the wording, or add a line underneath for a date, initials or a reference number.
- Change the colour if your office uses a different convention — red is the usual choice for this stamp.
- Download a transparent PNG (or SVG with Pro).
- Place it on a PDF or Word file with the document stamp tools, or print it on labels.
Frequently asked questions
Why is SPECIMEN printed diagonally?
A diagonal mark crosses the whole face of the document, so it cannot be trimmed off without the damage being obvious.
Does the mark stop misuse by itself?
It signals the document has no value; it is not a security feature. Keep specimens out of circulation as well.
Legal & usage
An office stamp is a status marking, not a signature, certification or official classification. Use it on documents you are entitled to annotate, and do not use it to misrepresent a document's status to others.
