The need for annealing the internal magnetic shield of a cathode ray tube to eliminate registration errors caused by non-uniformity of magnetic properties of the shield resulting from the forming process, is eliminated by using a shader plate with a convex curvature to adjust the screen pattern to compensate for such errors.
