Vandercook SP25

Vandercook SP25

Paul Moxon

(1963-76)

The SP25 was specifically designed to print full newspaper page proofs and also large repro proofs, from metal type forms on specially formulated paper, which were then used to make photo-litho plates for offset printing. Unlike earlier Vandercook models, the impression cylinder is automatically in print mode when at the feed board, thus there is no movement of the eccentric during the forward carriage travel unless it is manually shifted into trip mode. It features the “quick change” rollers introduced with the Universal series. The SP25 was available with an optional power carriage. The gripper bar (simpler and lighter than earlier models) is the same style found on later Universals. Power ink distribution and an automatic wash up unit was standard. Optional features included a power cylinder and an ink fountain for handling volume proofs. Maximum form: 24 × 26″; maximum sheet: 24½ × 28″. A dozen SP25 presses are represented in the Vandercook census. See also SP15 and SP20.
