ABSTRACT:
An improved process is provided for forming at least one set of elements of a patterned CRT screen disposed in overlay relationship upon an opaquely defined windowed-webbing priorly applied to the interior surface of the tube viewing panel in accordance with an apertured mask. The invention concerns the placement of a reflective medium over the exterior surface of the panel during screen exposure. By this means the exposure radiation traversing the screen and panel is reflected back through the respective windows in the screen structure to augment the polymerization and adherence of the pattern elements.
