Abstract
Silk-screens of annular-shape are provided for the silk-screen printing of halftones on compact discs. The silk-screens are rotatably provided in a carrier so that the angle at which moire can be eliminated or at least minimized or localized for the printing of a particular color can be determined. Following the determination of that angle for each of the colors to be printed, the screens are each then provided with photosensitive emulsion, exposed to light, and washed. The silk-screens are then placed in another carrier at the same angle as before determined for the elimination or at least the mimimalization or localization of moire, this carrier being capable of being placed directly into the nest of a print head of a conventional silk-screen printing machine.
