Founder
Mac McCormack founded Dupli-Graphic, now known as Dupli-Group, in Chicago just after World War II. Returning home from military service, Mac carried with him the discipline and dedication he learned while serving his country, and he channeled that work ethic into building a small, quality-driven print business from the ground up. As Founder, he established the core principles that still define the company today: meticulous attention to detail, honest craftsmanship, and a genuine commitment to customer satisfaction. Under his leadership, Dupli-Graphic quickly earned a respected reputation within the Chicagoland graphic design community and the broader Illinois printing industry. Mac's legacy as a hands-on, quality-focused founder laid the foundation for two generations of family leadership and nearly 80 years of trusted service to Chicago area businesses.

Second-Generation Leader
Walter "Wally" McCormack is the second-generation leader of Dupli-Group, building on the foundation established by his father, founder Mac McCormack. Taking the helm of the family business, Wally recognized the need to modernize and expand the company's capabilities to meet the evolving demands of the Chicagoland graphic design community. He spearheaded the company's transition into digital printing, direct mail, and wide-format services, and became a true industry pioneer by leading one of the first adoptions of the HP Indigo press in Illinois, enabling flexible, short-run, on-demand digital printing. Wally also championed environmental responsibility, guiding Dupli-Group to become an early adopter of Forest Stewardship sustainable printing techniques and transitioning the company to 100% soy ink usage by 2005. His forward-thinking leadership transformed Dupli-Group into a modern, full-service print solutions provider while preserving its heritage of quality and craftsmanship.
