Abstract
A calibration station ( ) for a printhead ( ) adapted to provide a beam of electromagnetic radiation from a variable electromagnetic energy source onto a sensitive radiation medium, the calibration station ( ), incorporates a sensor ( ) disposed for sensing the beam ( ) provided by the printhead ( ), wherein the sensor ( ) provides an output sensor signal indicative of the sensed power of the beam ( ). A control circuit is adapted to accept the output sensor signal from the sensor and adjusts the variable electromagnetic energy source. A filter is disposed in the path of the beam ( ) between the printhead ( ) and sensor ( ), adapted to transmit to the sensor ( ) a portion of incident electromagnetic radiation over a predefined range of wavelengths, dependent upon a measured response characteristic of the radiation-sensitive medium.
