AAA Printing Company on Santee's Prospect Avenue has operated as a commercial print house since approximately 1971, producing offset and digital collateral from Suite F at 10054 Prospect Avenue in the Woodside-Prospect industrial corridor. Property-marketing packages including full-color brochures, listing sheets, and door hangers run through the facility's offset presses for brokerages such as Mission Realty Group at Town Center Parkway, where print runs align with new-listing launch schedules. The shop's offset-lithography capabilities handle multi-color Pantone-matched runs on coated and uncoated stock, while digital presses cover short-run variable-data jobs including numbered forms, personalized mailers, and serialized tickets. Bulk direct-mail campaigns route through the shop's USPS-compliant presort and tabbing line, a fulfillment channel that marketing firms including Ashlynn Marketing Group Inc on Hartley Road use to distribute branded campaign collateral across ZIP 92071. Production-floor equipment includes a multi-unit offset press capable of four-color process printing at 15,000 impressions per hour on sheet sizes up to 19 by 25 inches, fed by a plate-imaging system that converts digital files to aluminum printing plates without chemical processing.
