Modelling and Simulation of Complex Manufacturing Systems.

A magnetic master is provided by premagnetizing a magnetizable recording member, forming characters on the backing layer of the recording member with a typewriter or suitable marking means, and exposing the recording member from the backing layer side to flash energy to demagnetize the background areas and form a latent magnetic image. The latent magnetic image may be contacted with a magnetic toner and the developed image transferred to a receiving surface where it is permanently fixed. The magnetic master may be developed hundreds or thousands of times to produce the desired number of prints.
