  • System of printing standardized cathode ray tube screens
    Patent number: 5158491
    Abstract: A system for standardized printing of CRT screens is disclosed. A preferred embodiment utilizes a standardized photoexposure stencil made without the use of a shadow mask aperture pattern and projection printing. The stencil is then placed in proximity to the screening surface during exposure. Front panel and mask support topography preparation methods and apparatus are disclosed, as are means and methods for compensating for variations among panel assemblies utilized in standardized printing of the screens. The system thereby produces high resolution screens which may accept interchangeable shadow masks.
