The present invention is directed toward a system to vary dimensions of a
template in order to attenuate if not prevent distortions in an
underlying pattern formed by the template. To that end, the system
features a compression device that includes a pair of spaced-apart
contact members to compress a perimeter surface of the template between
the pair of spaced-apart contact members. The compression device includes
first and second bodies, each has a contact member and an actuator arm.
One of the actuator arms is coupled to the first body to reciprocate
about an axis in response to variations of a volume of a bladder disposed
adjacent to the actuator arm. In this manner, the distance between the
two contact members may be varied.
