Vandercook & Sons was a manufacturer of proof presses, founded in 1909 by Robert Vandercook. They dominated the 20th century proof press industry by developing the first and the most widely used proof presses that did not rely on gravity for the force of their impression. As a result, Vandercook's geared presses were easier and more precise for an operator to use. Vandercook was sold in 1968 to the Illinois Tool Works, when it became Vandersons. The company changed hands many times and is now called NA Graphics, a letterpress supply house, located in Silverton, Colorado. History In September 1909, Robert Vandercook founded Vandercook & Sons in Chicago, Illinois. The first press was a “rocker” proof press, made with a geared cylinder. Before the development of this press, all proofs were either made on a roller press, which depended on gravity for impression or on a Washington Hand Press. During the next 54 years they introduced 60 different press models. Over the course of its 75 year production history, Vandercook manufactured more than 38,000 presses under its brand name. The name of Vandercook & Sons was used until 1968 when E.O. Vandercook sold the company to one of their suppliers, Illinois Tool Works. They only kept the company for four years and then sold it to one of their managers, Hugh Fletcher, who renamed the company Vandersons Corporation. Vandersons stopped manufacturing presses in 1976 at which time they only made models HS27, SP20, SP25 and Universal I. After ceasing to manufacture presses, Vandersons continued selling parts and supplies for the thousands of presses that were still being used. In 1989 the company was sold to Stuart Evans. In January 1994, Tom Bell and Hal Sterne of NA Graphics bought the company and moved it to Cincinnati, Ohio. Then in October 1996 they sold NA Graphics to Fritz Klinke who moved the operation to Silverton, Colorado. NA Graphics is still selling parts and supplies for many of the models of Vandercook presses. Press models Before World War II, Vandercook developed 29 models, 17 of which were still being manufactured many years after the war. The most popular of these models was #4, which was first made in 1935 and not discontinued until 1960. Many are still in use today. In 1948 they brought out the model 4T, which was used to pull transparency proofs of type on acetate. The acetate proofs
