Apparatus is provided for the silk-screen printing of the top surface of a compact disc. Each compact disc is registered in a precise location prior to being printed. A compact disc is registered by an elongated registration pin which is raised vertically upwardly so as to intrude into the center hole of the compact disc from the bottom surface of the disc.

Multicolor printing system for the silk-screen printing of compact discs

Apparatus for the transfer of ware in step-wise fashion from one point to another with silk-screen printing of the ware between the remote points. The articles of ware, in spaced-apart locations, are moved by an elongated horizontally disposed beam having a plurality of spaced-apart wareholders from a rearward horizontally disposed rest position downwardly in an arcuate path and then upwardly to a second forwardly located rest position in the same horizontal plane. The articles of ware are then each clamped while the beam reverses direction. A further article of ware is placed in the first wareholder, the other forwardly located articles being received in respective forwardly located wareholders. The beam then again moves forward and the articles of ware are each clamped. The beam then reverses direction, receiving a further article, etc. At the print station the articles are each raised vertically upwardly in a smooth curve, printed, and then lowered vertically downwardly in an opposing smooth curve. The printed articles are then forwarded downstream to other work stations.
