An apparatus and process for the manufacture of silk-screens is provided for use in the printing of halftones, e.g. in a four color printing process. The angle at which the mesh of a silk-screen should be relative to the screen frame to eliminate or at least minimize or localize moire' is predetermined for each of the color film separations. This angle is then carried to stretching apparatus for the woven fabric from which the silk-screens are to be made. The stretching appararatus has a table that is provided with a plurality of rotatable members. A screen frame is placed on each of the rotatable members and the rotable member is rotated to the angle determined by the pre-registration apparatus. The fabric is stretched to the desired tension and the screen frames having been provided at the desired angles are adhered to the stretched fabric, resulting in the mesh in each silk-screen being at the correct angle with respect to the screen frame.

Process for the preparation of silk-screens for use in printing half

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 minimization 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.

The silk-screens are rotatably provided in a carrier so that the angle at which molre can be eliminated or at least minimized or localized for the printing of a particular color can be determined.

Apparatus for simultaneously manufacturing multiple annular shaped

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.
