A plugged, worn or chipped hole in a jet strip leaves a lane where fibers are entangled less or differently, which shows as a light, dark or weak line along the whole roll. Streaks are found by holding the fabric to the light or with cameras, and their position is matched to the strip. The fix is a strip change and better water filtration.
Jet streaks at 1.4 and 2.2 meters, both under injector three, so it's that strip.
Log streak positions in centimeters from a fixed edge of the fabric; that number leads straight to the injector and the hole.
