Most modern jigsaw puzzles are made out of cardboard, since they are easier and cheaper to mass produce than the original wooden puzzle models. An enlarged photograph or printed reproduction of a painting or other two-dimensional artwork is glued onto the cardboard before cutting the jigsaw puzzle. This board is then fed into a press. The press forces a set of hardened steel blades of the desired shape through the board until it is fully cut. This procedure is similar to making shaped cookies with a cookie cutter. The forces involved, however, are tremendously greater and a typical 1000-piece puzzle will require a press which can generate upwards of 700 tons of force to push the knives of the puzzle die through the board. A jigsaw puzzle die comprises a flat board, often made from plywood, which has slots cut or burned in the same shape as the knives that will be used. These knives are set into the slots and covered in a compressible material, typically foam rubber, the function of which is the ejection of the cut puzzle pieces.
