This disclosure depicts a novel low cost, high performance color cathode ray tube of the shadow mask type, and methods and apparatus for manufacturing the tube. The tube has a novel envelope, on a faceplate portion of which is corner-suspended a lightweight, non-self-rigid shadow mask. The tube has a variety of features and is especially adapted to be made by manufacturing methods which permit the screened faceplates to be interchanged, each with all others, and the shadow masks to be interchanged, each with all others, with consequent economies in manufacture and enhanced tube performance. This disclosure stresses the structure of masters employed in the making of the screen.
