The large and small tympan are parts of the printing press. The former is made from a sheet of parchment glued to a wooden frame which is attached to the end of the carriage by two hinges. On this tympan , once it has been moistened with a wet sponge, is placed the sheet of paper in preparation for its pass through the press. The small tympan is also a sheet of paper glued to a smaller frame which folds over the back of the large tympan ; between these two membranes, or tympans , are placed the blankets and card. See Points, Blankets, Card.
