Founded in 2007 as a small screen-printing shop, DKM Sales became Lancaster Specialty Printing after moving into a 38,500-square-foot facility in Lancaster, New York, in 2023. The company creates custom signs and graphics, with a production team whose design work is grounded in hands-on manufacturing experience. Its 2018 acquisition of RealEstateSigns.com also gives it a dedicated business serving real-estate agents.
