ABSTRACT OF THE INVENTION A method for preparing a supplemental intensity- correction filter for an exposure lighthouse that is used to print viewing-screen structures for cathode-ray tubes. The method involves printing a screen structure without a supplemental filter, calculating how incremental areas of the light field must be modified at the surface of an optical element of the lighthouse to produce the desired screen structure, and then printing a supplemental filter on that surface having the transmission characteristics necessary to modify the light field as required.
