ABSTRACT:
An alignment system for aligning the print plates of a two-sided contact printing station includes expanding pin assemblies each having an expanding collet and a mandrel for engaging and aligning match drilled holes in each of the print plates. An expansion cylinder moves the mandrel into and out of engagement with the expanding collet to cause the collet to expand into engagement with the match drilled holes. The outside profile of the expanding collet forms a straight-pin diameter which corresponds to the diameter of the match drilled holes when expanded. The expanding pin assemblies may be contracted to facilitate moving the print plates apart for advancing the working material.
