ABSTRACT:
A registration board capable of dissipating static electricity through a conductive sink for use in a vacuum frame exposure system. The board comprises a bottom layer with channels and slots for registration pin flex plates, a middle layer for spacing and with guide holes for the registration pins, and a top layer of a conductive and resiliently compressible material. The static electricity that builds up from movement of materials in a vacuum frame printing process is bled off the conductive top layer through a conductive element placed between the top and middle layer and extending to the underside of the bottom layer which can either merge the static electricity with the greater field of the blanket or be selectively attached to an external ground connector.
