Abstract: The present disclosure relates to a color measurement apparatus (100) for measuring a color on a printed item (9). The color measurement apparatus (100) comprises a first body (1), a second body (2) including a sensor (26) for measuring color data of a printed item (9), and a guiding rail (3). The second body (2) is movable relative to the first body (1) along a measurement direction (210) and the guiding rail (3) guides the movement of the second body (2) relative to the first body (1). The guiding rail (3) is positioned between the first body (1) and the second body (2). The second body (2) is slidingly mounted on the guiding rail (3) and can slide along the guiding rail (3) in a first sliding direction (210); the guiding rail (3) is slidingly mounted on the first body (1) and can slide along the first body (1) in a second sliding direction (310) parallel to the first sliding direction (210).
