ABSTRACT:
A method of manufacturing luminescent screens (2) for, e.g., color picture tubes is described. It uses a printing apparatus with heated printing blocks (3) and tampons (4). The printing inks (D) consist of a mixture of a hot-melt adhesive and the respective luminescent materials. The printing inks are printed from the printing blocks directly on the inside of the faceplate (1) of the color picture tube. It is also possible to first print a black matrix (M) of a ceramic glass color.
