An improved method of forming a reconfigurable relief surface using an electrorheological fluid

摘要

A structure and method of using a reusable master printing plate is described. In one embodiment, the viscosity of an electrorheological fluid is adjusted using an electric field to control its flow and create the desired relief pattern in a flexible printed surface. 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.
