Buying Guide
What type of seal do you need?
- Self-inking: fast, clean impressions; good for high-volume stamping.
- Pre-inked: long-lasting impressions; easier for thousands of uses.
- Hand stamp: traditional, reliable; requires an ink pad.
Which state requirements matter?
- New York, California, Oklahoma, and other states have specific seal styles and image sizes. Confirm the required image size (commonly 1.75 inches) and whether a licensed seal is needed on each document.
- Some products advertise state-specific licensing; ensure the stamp matches your professional credentials for your jurisdiction.
How often will you stamp?
- For frequent use, choose self-inking or pre-inked options to minimize downtime and maximize imprint consistency.
- Occasional stamping may benefit from a hand stamp due to its lower upfront cost and simplicity.
Imprint quality and maintenance
- Self-inking and pre-inked stamps offer cleaner, more legible impressions; check for imprint sharpness and alignment.
- Pre-inked units generally require less maintenance but may need re-inking over time.

FAQ
- What is the main difference between self-inking and pre-inked stamps?
Answer: Self-inking stamps have a built-in ink pad that automatically re-inks the die after each imprint, while pre-inked stamps contain ink inside a reservoir and offer thousands of impressions without a separate pad. - Do these stamps require a separate ink pad?
Answer: Some models are self-inking or pre-inked and do not require an additional pad; hand stamps typically require a separate pad. - Are state-specific seals legally required on all documents?
Answer: Requirements vary by state and project; verify your state licensing board’s guidelines for seal usage and size. - Can I order a stamp for multiple states?
Answer: Yes, but ensure the seal pattern matches each state’s official design and size requirements to avoid compliance issues. - What maintenance is needed for pre-inked stamps?
Answer: Re-inking may be needed periodically to maintain imprint sharpness, depending on usage and ink capacity. - Is a stamp appropriate for official plans and regulatory submissions?
Answer: When it matches state requirements for an engineer seal and provides clear, legible impressions, a stamp is appropriate for official documents.
