Business Paper with 25% Cotton

Southworth 403C business paper contains 25 percent cotton fiber for a distinctive texture and crisp feel. Each 20 lb sheet is watermarked and date-coded for document authentication. The wove finish provides a professional surface for letterheads, contracts and reports. Acid-free, lignin-free stock is compatible with laser printers, inkjet printers and copiers.

Suits Legal and Formal Documents

Professionals preparing briefs, pleadings or presentations gain a rich look and reliable feed-through. Buyers who need coated photo paper or heavyweight card stock for graphics should look elsewhere. The letter-size format fits standard office trays but does not serve wide-format or custom-size requirements. Coordinating envelopes are sold separately.

500 Sheets per Box

One box delivers 500 sheets of 8.5 x 11 inch paper for high-volume printing. FSC certification confirms the wood comes from a certified managed forest. The 20 lb basis weight balances substance with everyday handling. Watermark and date-code on every sheet support document verification.

Questions about this item

What paper size and weight does the Southworth 403C box contain?

Each box holds 500 sheets of letter-size stock measuring 8.5 x 11 inches at a 20 lb basis weight.

How should I load the watermarked sheets so the mark reads correctly?

Fan the stack, then place it in the tray with the watermark facing up and reading left to right; the date-code will then appear in the same orientation on every printed page.

Will the acid-free, lignin-free composition keep printed documents from yellowing over time?

Yes, the 25 percent cotton fibre stock is both acid-free and lignin-free, so letterheads, contracts and briefs resist discolouration and remain archival-quality for decades.
