ABSTRACT Process and apparatus are disclosed for use in the manufacture of a color cathode ray tube having a shadow mask with a central pattern of apertures mounted in tension on a transparent flat front panel. The mask aperture pattern is registered with a catholdoluminescent screen pattern of corresponding geometry and position on an inner surface of the panel. The shadow masks and front panels are respectively interchangeable. In one embodiment, inter- registry of a screen pattern with a tension mask aperture pattern is achieved by stretching or otherwise expanding the mask to a predetermined standard. In other embodiments, signals are developed which are indicative of the positions of a mechanically stretched mask aperture pattern and an associated front panel screen pattern relative to a reference or to each other. Responsive to such signals, there is effect- ed a relative positioning of the mask and screen until registration between the patterns is achieved.
