Inspector Gadgets

However, the highest quality inspection systems aren't necessary for every converter, and with so many options and confusing characterizations of the newest technology, knowing what system to choose can be difficult.

What to look for

There are three basic requirements a web inspection system should include, said John Woolley, vice president of sales and marketing at PC Industries (Gurnee, Ill.): high-resolution digital cameras, high-speed computer processing, and automatic print defect detection. High-resolution digital cameras produce better image detail and clarity, and faster computers are necessary for 100 percent web inspection, Woolley explained. Automated defect detection capabilities automatically alert the operator to changes in print quality.
