Envelopes Printing & Pre-Press FAQ

Direct specifications, customization details, and turnaround timelines for Envelopes.

What are the rules for custom envelope printing and the 10% ink coverage guideline?

The Office Annex prints custom #10 business envelopes, including high-open-rate Peel-and-Seal envelopes ideal for direct mail. Standard commercial envelope pricing applies to designs with less than 10% total ink coverage (typically a logo, return address, and teaser line). Our platform automatically detects ink coverage during pre-flight so you always get accurate, transparent pricing before checkout.

Pairing custom teaser copy on a #10 envelope with our machine-folded (Tri-Fold or Z-Fold) 8.5" x 11" flyers allows you to stuff and mail campaigns immediately upon delivery without manual folding.

Can you print recipient addresses or leads directly onto my postcards and envelopes?

Yes. On eligible postcards and #10 envelopes, you can upload or email your own CSV mailing list to be printed directly onto each mailpiece for $0.03 per address, or purchase targeted opportunity-seeker leads printed directly onto your mailers for $0.12 per piece.

Direct-to-piece Inkjet addressing eliminates sticky peel-and-stick labels, lowers your labor time, and gives your direct-mail campaign a clean, commercial mailhouse appearance.

How long does production and shipping take, and do you ship internationally?

Standard production turnaround at The Office Annex averages 3 to 5 business days from file approval. We offer multiple domestic shipping speeds across the United States as well as affordable international shipping for global marketers and businesses.
