How it compares
- The finish principles (matte for editorial, UV for photo, silk lam for keepsake) apply across most paper-stationery formats.
- Text-weight stock (60lb, 70lb, 80lb, 100lb) maps directly to brochures, notepads, and envelopes.

How should I prep my file?
Build at the final trim size plus 0.125" bleed on every outer edge. Keep important text and logos at least 0.125" inside the trim line. For folded products, account for the fold position when laying out panels — the configurator shows the per-panel safe zones. Export as press-ready PDF at 300 dpi in CMYK. Outline fonts before export.
Will the envelope clear USPS for automated mail?
Standard #10 business envelopes (4.125×9.5) clear USPS automation. Self-adhesive variants are pre-glued for sealing. Window envelopes have a clear panel cut into the front face for a printed address card. Always test a sample with your mailing partner before printing in bulk.
How long does production take?
Most paper-stationery formats run 3–5 business days from file approval, plus shipping. Specialty finishes (foil, spot UV, die-cut, lamination) add 1–2 days. Larger quantities don't meaningfully extend production because press setup dominates short to mid runs.
