AUXILIARY METHODS

There are other reprographic methods which although commonly used earlier, are now mainly used for specific purposes. We think you should be aware of these methods also.

Thermograph : Used mainly for preparation of reprographic masters, e.g. hecto, stencil, etc. A cheap method ideal for large originals, e.g. circuit diagrams, engineering drawings, construction plans, etc. (Blue prints)

Microfiche : This is a standardized form of microfilm storage of information. Such a system allows the storage of approximately seventy-two pages of A4 per slide. The slide is viewed by placing it into a viewer, which projects enlarged sections of the slide onto a screen.

Microfiche systems allow high density storage of any material which can be photographed.
