Blue Ink or Black Ink?
What Oregon Notaries Need to Know
By Oregon Notary Network
As a notary public in Oregon, you’ve probably encountered this question more than once: Should I use blue ink or black ink to notarize documents?
It really does seem like a simple choice—yet it can feel surprisingly complex. Clients may have strong opinions, documents may have specific requirements, and notary forums are filled with debates. So, what does Oregon law actually say about ink color?
Let’s break it down.
Here’s the good news: In Oregon, the statutes and rules do not specify which ink color a notary (or clients) should use when signing documents.
According to the Oregon Secretary of State, the law does not mandate black, blue, or any other specific color of ink for notarial certificates or journal entries. That means you're not violating any regulations by choosing one over the other. However, that doesn't mean ink color is irrelevant—because the real answer lies in context.
However, just because Oregon law is silent on ink color doesn’t mean the documents themselves are. Always read the document instructions.
Some documents—especially real estate, government, or legal forms—may include explicit directions such as:
“Sign in blue ink only.”
“Black ink required for recording.”
“No red or gel pens.”
These instructions should be followed precisely, even if they seem minor. Using the wrong ink color could cause a document to be rejected by a recorder’s office, a title company, or a legal entity. This could delay a transaction, frustrate your client, or lead to questions about your professionalism. Even worse, since Oregon does not require insurance, if one of the above-mentioned parties to the transaction decide to act on the financial loss of the delay, not reading the instructions for the notary and the document could end up being a very expensive mistake.
So, before you uncap your pen, scan the document for ink color instructions. If none are present, consider the type of document, the client’s preferences, and industry norms.
But Why is Blue Ink So Important?
Blue ink is often favored for one simple reason: visibility. A blue signature stands out clearly against black text, making it easier to verify that a document is an original and not a photocopy.
Some signers or companies request blue ink to distinguish the signature from printed content. It can also help reduce fraud by making it obvious when an original document has been altered or copied.
However, some scanning and faxing systems may struggle with lighter shades of blue ink, making legibility a concern if the pen quality is low.
Black Ink
Black ink is the traditional choice for many professional settings. It's bold, legible, and universally accepted across courts, banks, and government agencies. In some cases, black ink is specifically required for archival or imaging systems, as it's more consistently readable in scanned or microfilmed formats.
Because it’s often considered a default, black ink tends to be a safe bet—unless the document says otherwise.
What About Notary Seals/Stamps?
Oregon notaries are allowed to use an inked rubber stamp for their official seal. The ink color of your stamp should also follow one key rule: it must be legible and photograph reproducible.
Many notaries choose black ink for this reason, though blue can be used if it creates a clear impression. Avoid red or green, as these may not photocopy well or could be rejected.
Pro Tip: Make sure your seal ink contrasts well with your document paper color.
Best Practices for Ink Choice
Here are a few professional habits to help you stay compliant and confident:
Always read the document for specific instructions about ink.
Keep both black and blue pens in your notary kit. This shows preparedness and flexibility.
Match your signature ink to any client instructions or industry norms.
Use consistent ink color for the notary certificate, your signature, and the client’s signature when possible (unless otherwise directed).
Avoid using pencil, red ink, or erasable pens under all circumstances.
So, while ink color may seem like a small choice for notaries, it's another opportunity to show care, attention, and professionalism. Whether you reach for blue or black, your real power lies in being aware, adaptable, and well-informed.
When in doubt, ask the client or document issuer. And if you ever feel unsure—remember: the safest path is to read carefully, follow the instructions, and stamp with confidence.
