Inspector Gadgets

One hundred percent inspection systems use a line CCD camera that takes a line of pixels from one side of the web to the other—covering every inch of the web, all the time—and memorizes the pixel formations, explained Shumaker.

Woolley added, "One hundred percent inspection can be accomplished using high-speed digital area scan cameras. The latest systems can merge multiple cameras mounted across the web and triggered down the web which provides true 100 percent continuous inspection of the web and a full image of the entire repeat."
