Abstract
A method for printing a viewing-screen structure including projecting, at least three times, a light field from a light source, through a lens, an optical filter and incident upon a photosensitive layer. During one of the projecting steps, the light source and the nominal axes of the light source, the lens, the filter and the layer (which are substantially parallel to one another) are aligned along a common axis. During each of the other two projecting steps, the light source and the axis of the lens remain aligned along the common axis, and the axes of the filter and the layer are offset prescribed distances on opposite sides of the common axis.
