Abstract
A method of detecting streaks in a web of, for example, moving paper which may be moisture, basis weight or caliper. A cross-direction profile is sensed and a moving average computed and then using minimum thresholds for the variation of the streak value from the average and its width in profile data boxes, the streak is detected.
