Abstract: A colorimeter for reading color bars (403, 404) of printed sheets (401) or the like includes a longitudinally extending base (400) including a paper stop (442) along which a sheet to be tested for color may be positioned. An autonomously operating colorimeter head (410) is moved along the base in a direction parallel to the edge of the sheet by means of an electric motor (600) mounted on the base and driving an helical thread lead screw (418) engaging an X-axis carriage supporting the head. The head is moved by operation of the lead screw in a direction parallel to the edge of the sheet, referred to as the direction of the X-axis. The head includes an electric motor and a Y-axis transport supporting an optics unit (510). The optics unit is moved within the head in a direction parallel to a Y-axis, extending perpendicularly to the X-axis.
