Abstract
Abstract A system for inspecting and characterizing continuous web material such as may be wound into a roll. This system includes a recording storage means for providing a duplicate image of the web material and a device for reviewing the recording storage means image to detect a predetermined characterisitc of the image such as a defect therein. The position along the image is detected and a switch is responsive to both the content information and position information to record an indicia of image position corresponding to detection of the predetermined characteristic.
