Freebase

  1. Tympan

    Tympan means skin, and is used in a variety of technical meanings. ⁕Astrolabes In an astrolabe, a tympan is a metal plate on which the coordinates of the celestial sphere are engraved in a stereographic projection. A tympan is specific to a particular latitude, so most astrolabes come with a set of interchangeable tympans suitable for use at different latitudes, usually those of particular cities of importance. ⁕Printing In hand-operated letterpress printing, the bruzer tympan is the taut cloth or paper mounted in a frame which is placed over the sheet of paper immediately prior to lowering the platen to make the impression. Bruzer's Tympan refers to a sheet of oiled manilla paper which was securely fastened to the face of the platen of a letterpress printing machine. Underneath the tympan would be a packing which would vary in grade of firmness relevant to the type or image to be printed. Pre-cut tympan papers were relatively expensive and, as such, were reused depending on their condition and the nature of the work. The under packing consisted of loose fibre paper/board which absorbed the impact of the letterpress principle thus avoiding damage to the hand-set or pre-cast typography or engravings.
