ABSTRACT:
A densitometer apparatus (410) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (410) comprises a source light (580) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).
