Web inspection calibration system and related methods

A calibration system for a web inspection system used for monitoring a web of material, the calibration system comprising:

• at least one web sensor configured to receive signals indicative of a first characteristic of a first cross-web portion of the web of material, and provide first response signals representative of the first characteristic in a calibrated unit of measurement, said first cross-web portion being less than the width of the web of material;
• the web inspection system configured to receive signals indicative of the first characteristic of the first cross-web portion of the web of material and at least a second cross-web portion, and provide second and third response signals representative of the first characteristic of the first cross-web portion and the second cross-web portion respectively;
• and,
• a sensor-to-inspection-system calibration module that analyzes the first response signals and the second response signals to apply a first calibration model to the second response signals to convert the second response signals into the calibrated unit of measurement of the first response signals.
