Blank check stock is ordinary paper with security features and no bank details printed on it. Everything specific to your account is added by the printer, which is why one box of stock works for every account you have.
Formats
| Format | Layout | Typical use |
|---|---|---|
| Check on top | Check, then two stubs | Business, accounts payable |
| Check in middle | Stub, check, stub | Payroll |
| Check on bottom | Two stubs, then check | Business, varies by accounting package |
| Three per page | Three checks, no stubs | Personal use, lowest cost per check |
| Wallet | Narrow checks, three up | Personal checkbooks |
Choose one and standardize. Software configured for check-on-top will happily print onto check-on-bottom stock and produce three unusable sheets before anyone notices.
Security features and what they actually do
- Microprinting. Text so small it appears as a line to the naked eye and blurs when photocopied. On the signature line and borders.
- Watermark. Visible when held to the light, cannot be reproduced by a copier or scanner.
- Chemical wash detection. Stains or reveals a void message if the check is treated with solvent to remove ink. This is the feature that defeats "check washing", the most common form of check alteration.
- Toner adhesion coating. Makes printed toner harder to lift off mechanically.
- Heat-sensitive icon. Changes colour briefly when rubbed or breathed on; a teller-level verification.
- Void pantograph. The word VOID appears when the check is photocopied.
- Security screen on the back, with a warning list of the features included.
- Padlock icon. Indicates the stock meets an industry checklist of security features. It is a claim about the paper, not a certification of your printing.
For a business paying contractors, chemical wash detection and microprinting are the two that matter most in practice. Related reading: check security features and check fraud prevention.
Paper weight and colour
- 24 lb is the standard. 20 lb feels flimsy and jams more; 28 lb is unnecessary for most printers.
- Colour is cosmetic, with one exception: very dark or heavily patterned stock can interfere with optical reading of the MICR line. Light backgrounds are safer.
Where to buy
Blank check stock is sold by office supply retailers, online marketplaces and specialist check printers. Price per sheet drops sharply with quantity — a 500-sheet box is usually far better value than 100 sheets, and the paper does not expire.
What to check before ordering:
- Format matches your software configuration.
- Size is standard 8.5 by 11 inches.
- The MICR area at the bottom is clear of pre-printed design.
- Your printer can handle the weight — check the specification for cardstock and heavy paper.
Storing it
Blank check stock is not cash, but it is closer to cash than ordinary paper. Keep it locked, count it periodically, and shred misprints rather than binning them. If a stack goes missing, tell your bank — positive pay and account alerts exist for exactly this.
Pre-printed stock is different
If you order checks with your bank details already printed, that is pre-printed stock and the software prints only the variable fields — payee, amount, date, memo. It is the right choice if you already have a supply of bank checks and want to stop writing them by hand.
