Abstract
A method of manufacturing a shadow mask tube for color imaging, in which, at least in one of several exposure stages used, a photosensitive layer, arranged in a window section of the tube, is exposed to the light from a light source by means of the shadow mask from two points located on each side of an exposure center, characterized in that optical correction means are produced between the light source and the window section that produce a virtual displacement of the light source, and why the said exposure phase is divided into at least two parts between which the optical correction means are rotated 180º about an axis that extends substantially at right angles to the section window.
