A structure and method of using a reusable master printing plate is described. In one embodiment, the method uses an electric field to control a series of microvalves. The microvalves control a fluid flow that raises or lowers selected regions on a flexible printing surface to create a desired relief pattern. After creating the relief pattern, the pattern is fixed and used for printing. After completion of printing, the relief pattern is removed from the master printing plate and the printing plate may be reused by applying a new pattern.
