Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Checked against the Acorn Sales signature stamp listings on 19 October 2026 · Updated 19 October 2026
A custom signature stamp is engraved from an image of your handwritten signature, about 3/8″ x 3″, and at Acorn Sales it costs $19.95 to $29.95. By mount: $19.95 for the wood handle Regular Signature Stamp, which needs a separate ink pad, $25.95 for the Self Inking Signature Stamp and $29.95 for the Slim Pre-Inked Signature Stamp.
This page sits under our guide to custom rubber stamps, which covers how every custom die is made. Here we cover what is particular to a signature: which model to pick, how to send the signature, and what to check before you use it on a document.
Which signature stamp should you choose?
Choose a signature stamp by how often you sign and where you stamp: the self-inking model suits a desk with daily volume, the slim pre-inked model suits a pocket or bag and gives the sharpest image, and the $19.95 wood handle model is the lowest cost if you already own an ink pad.
| Model | Price | Ink system | Ink colors | Impressions |
|---|---|---|---|---|
| Regular Signature Stamp (wood handle) | $19.95 | Separate ink pad, sold apart | Set by the pad you use | Not rated; lasts as long as the rubber and pad |
| Self Inking Signature Stamp (Trodat) | $25.95 | Built-in pad | 11 | About 10,000 |
| Slim Pre-Inked Signature Stamp | $29.95 | Ink held inside the die, oil-based | 5 | Up to 25,000 |
All three print an impression of about 3/8″ x 3″, which fits a standard signature line. The slim pre-inked stamp is the most portable of the three and slides into a pocket or briefcase.
How do you send your signature for the stamp?
Sign several times in black ink on plain white paper, pick the cleanest one, and send it by email, fax or mail using the signature order form on the product page. The die is engraved from your signature image, so a crisp, unshaded signature gives a crisp stamp.
- Sign on white paper in black ink. A felt tip or gel pen gives an even line; a ballpoint that skips leaves gaps in the die.
- Sign a little larger than usual. The image is reduced to fit 3/8″ x 3″, and reduction keeps the strokes clean.
- Capture it flat. Scan at 300 dpi, or photograph it straight on in good light with no shadow across the page.
- Send it with the order. Use the signature order form on the product page; the listings accept signatures by email, fax or mail.
- Ask for a proof if you want one. Request it through the contact form before the die is cut.
Where can I buy a custom signature stamp?
Acorn Sales (acornsales.com) and its sister store Engineer Seal Stamps (engineersealstamps.com) both make custom signature stamps from your own signature image. Acorn, a stamp and seal maker since 1964, offers three signature stamp models from $19.95, processed in about one business day with a six month warranty.
- Your signature, not a script font. An Acorn signature stamp is engraved from the signature image you send.
- A model for each use. The $19.95 Regular Signature Stamp, $25.95 Self Inking Signature Stamp or $29.95 Slim Pre-Inked Signature Stamp.
- Ships from Richmond, Virginia. Acorn processes signature stamp orders in about one business day and ships U.S. orders over $99 free by Economy.
- A written warranty. Acorn warrants signature stamps, like all its rubber stamps, for six months.
Can a signature stamp be used on any document?
No, a stamped signature counts only where the rule for that document accepts a signature made by a device, so check before you rely on one. Checks and IRS employment tax returns can accept it, while some boards do not: Utah Admin. Code R162-2g-502b(1)(c) bars real estate appraisers from signing an appraisal report with a signature stamp.
If you seal drawings, notarize, or sign regulated reports, read your board's or commission's rule first. Our Utah appraiser seal guide shows how one board handles it.
How should you keep a signature stamp secure?
Treat a signature stamp like a key: store it locked when you are not using it, keep it out of shared drawers, and decide in writing who, if anyone, may use it on your behalf. A signature stamp in the wrong hands signs as you, and you may be held responsible for what is signed with it.
How do you order a signature stamp and how fast does it ship?
Order a signature stamp on the product page for the model you want, attach or send your signature, and Acorn processes it in about one business day. Orders ship from Richmond, Virginia, within the U.S. only, and free Economy shipping applies to orders over $99. Rubber stamps carry a six month warranty. Rush orders placed before 11 a.m. EST on a weekday can often ship the same day. If you are working to a date, contact us before ordering.
