Techniques are described for inspecting a web and controlling subsequent
conversion of the web into one or more products. A system, for example,
includes an imaging device, an analysis computer and a conversion control
system. The imaging device images a sequential portion of a web to
provide digital information. The analysis computer processes the digital
information with an initial algorithm to identify regions on the web
containing anomalies. The conversion control system selects one of a
plurality of converting sites to convert the web into a product, and
analyzes at least a portion of the digital information with at least one
subsequent algorithm to determine which anomalies represent actual
defects in the web for the products.
