Abstract
In combination, a guide body/matrix body assembly and a precision punch set assembly and method, the combination forming a precision punching system for highly accurate registration hole placement in film and plate sheet material used in subsequent precision alignment thereof on printing presses and image platemaking. The punch set assembly includes a punch guide and a punch matrix which are precision installed into the guide body and matrix body, respectively, in highly accurate fashion with respect to substantially all lineal and rotational degrees of freedom through the use of slightly oversized holes in the guide body and matrix body and a curable adhesive which fixes the precision alignment when cured. Vibration applied to the guide body/matrix body assembly during precision alignment and orientation of the punch set assembly is preferred.
