Anastatic \An`a*stat"ic\, a. [Gr. ? up + ? to make to stand: cf.
   ? causing to stand.]
   Pertaining to a process or a style of printing from
   characters in relief on zinc plates.

   Note: In this process the letterpress, engraving, or design
         of any kind is transferred to a zinc plate; the parts
         not covered with ink are eaten out, leaving a facsimile
         in relief to be printed from.
