Abstract
A photographic printer control system of the present invention separates the operation of the printer into first and second working levels. The first (or 'operator') working level includes selecting the printing mode, loading or selecting one of a plurality of setup blocks, initiating printing, and applying color density button corrections. The second (or 'manager') working level includes determination of printer operating parameters for each setup block, selection of automatic corrections to be applied, color balancing, calibration, and totalizing. A control panel supplies input signals which select and control operation on the first and second working levels. A security system is provided to limit access through the control panel to the first working level for all persons except authorized persons such as the lab manager. The regular operator of the printer, therefore, normally cannot initiate operation on the second working level and thereby disrupt operating parameters, color balance, calibration, or totals which have been selected by the lab manager.
