Cal Copy in Grantville has operated as a full-service duplicating and digital print shop for San Diego since 1984, making it one of the longest-running independent copy centers in eastern San Diego County. Owner Rahim Mansoorgholamshahi runs the production floor at 6367 Alvarado Court, Suite 104, a 92120 address tucked into the Alvarado Canyon commercial zone off Fairmount Avenue. The same Grantville corridor feeds custom apparel work to Shirts On Tap, which handles the garment side of promotional campaigns while Cal Copy covers the document and large-format output. The shop produces black-and-white and color copies, large-format posters, blueprint reproductions, laminated documents, spiral-bound and comb-bound presentations, and passport photos. The Better Business Bureau has maintained Cal Copy's A+ accreditation since the company's file opened in 2000, a 25-year compliance record. SDSU students and faculty use the shop for course-reader printing, thesis binding, and research-poster output sized for academic conference display boards. The Alvarado Court suite sits less than a mile from the Grantville Trolley station, giving the shop walk-in access from the Green Line transit corridor. Variable-data printing supports numbered forms, sequential invoices, and personalized direct-mail pieces. Businesses preparing event photography portfolios or trade-show collateral coordinate image capture with Paul Douda Photography in San Carlos, then route finished files to Cal Copy for large-format output and foam-core mounting. The shop also handles fax services and document scanning for law offices and medical practices in the surrounding Grantville office parks that still process paper-heavy intake files.
