Abstract
Web measurement system monitors properties of a web during manufacture without chopping measuring radiation during web measurement. A single chop is performed at each sheet edge or every nsheet edge to measure edge temperature and edge thermal radiation for correction for Planckian radiation. Correction factors, including Planckian radiation correction factors, are derived for each point in a web profile. The measuring system also enables derivation of correction factors during operation in a single point and similar machine operating modes.
