A SoCal union shop, built for the work that has to land.
We're a Southern California print and mail team operating under Allied Printing Trades standards — same union bug whether you're mailing 250 invitations or four million political pieces.
OCUnionPrint exists because the print and direct mail buyers we serve — political campaigns, labor councils, FQHCs, school districts, nonprofits — need a partner who picks up the phone in California, understands union rules, and treats deadlines the way the work demands.
We operate as a division of Universal Mailworks Inc., a long-running union-shop print and mail operation based in Buena Park. Every job runs through Allied Printing Trades–affiliated facilities so the bug on your piece is real, not decorative — and printed on the press sheet, not slapped on as a sticker.
Our team has helped move ratification ballots in 36 hours, mailed county-wide school bond programs on tight in-home windows, and produced multilingual voter outreach across LA, OC, San Bernardino, and Riverside counties. We're not the cheapest printer in California — but if your work has a deadline, a council, or a bond measure attached to it, we're the team to call.
