Abstract
A device and a method for exposure of visual data onto light-sensitive recording material, a light source which emits light in at least one color, and a control unit for regulating the light amount. The control unit is connected to a light measuring unit. The light measuring unit has at least two detectors, which measure at least two different spectral components of the same exposure color. The control unit and the light measuring device form a closed loop control circuit.
Claims20
In a device for exposing image data onto light-sensitive recording material, said device comprising a light source that emits light in at least one color, a control unit connected to the light source for regulating the quantity of emitted light, and a light measuring device, connected to the control unit, said control unit and said light measuring device forming a control circuit, the improvement wherein the measuring device has at least two detectors which measure at least two different spectral components of the same color.
In a method for exposing image data onto light-sensitive recording material, whereby a light source emits light in at least one exposure color, the emitted light is measured, and the light source is regulated according to measured light, the improvement comprising the steps of:
- measuring at least two different spectral components of the same exposure color and calculating control parameters from the measured values.
