Abstract: A method for producing a color kinescope having an image screen and a color-selection mask comprising final-size apertures. The method includes the steps of providing at least one perforated resist layer on a metal substrate and removing through the perforations of the resist layer both certain portions of the substrate so as to provide corridors of a given size through the substrate and other portions of the substrate adjacent to the corridors, so as to provide recesses extending only partially through the substrate thereby producing a preliminary mask. The image screen is produced with the preliminary mask, and, then, portions of the substrate located beneath the various recesses are removed so as to produce a color-selection mask comprising final-size apertures of larger size than the corridors. The color selection mask is then incorporated in a kinescope.
