Inspecting Continuous Webs

Materials produced in a continous roll or sheet, such as paper, textiles, film, foil, plastics, metals, glass, or coatings, are best inspected by line scan systems. Line scanning offers unlimited pixels in the in the direction of a web's motion with zero smear even at high speeds, higher dynamic range, greater processing efficiency and much lower price/pixel.

100% print inspection

Large web inspection

Plastic film production

Glass inspection

Line scan systems provide higher resolution with fewer cameras and inspect 100% of a moving surface without smear or the need to process frame overlaps.
