An X and Y coordinate plotting machine consisting of a fixed or rotating table and movable head, on fixed ways,
that is capable of precisely locating a point on a line or surface. Coordinatographs were commonly used with cutand-strip scribe-coat materials to generate artwork. Now they are mainly replaced by CAD production of artwork
master files. Coordinatographs can also be used for accurately measuring film work or flat parts.
