About Tandem Tandem Printing was founded in 1954 by Bob and Marilyn Jensen of Richfield, Minnesota. For 37 years the Jensen's established a reputation for quality, reliability, service and integrity as they built their company working in Tandem as a husband and wife team. As the years passed by, the appeal of retirement became stronger and in 1991 a new Tandem, John Kostka and Steve Kane, acquired the company and have continued the values and tradition that had begun several years before. Our experienced staff offers individuals and businesses both large and small the latest computer-to-plate technology, one-to-six color offset printing, large format printing and digital color and black and white
