The Dickerson Combination Press is a printing press invented by Edward "Ted" Dickerson. It was made for intaglio printing, relief printing, and lithography. It could be used either electrically or hand driven. It earned patents in the United States (U.S. Patent No. 3067676) and Great Britain (British Patent No. 238,946).
The acetate proofs could then be contacted to film for offset negatives. During World War II not many presses were made because Vandercook was heavily involved in manufacturing for the war effort, for which they received the E award. One press they made for the government during the war was a model 055, 51″ x 75″ in size.
