Offset
plate (part 3)
We
bought one of the first models of the Xerox machines. This had three
parts: a camera, a unit in which the toner and developer were
cascaded over the exposed selenium plate and transferred to the copy
paper or offset plate, and a fuser. We had to modify our paper plate
to permit proper fusing. When Xerox produce the later models of
electrostatic copiers without a camera and fuser, with the assistance
of Ken Shimazu, we made a paper offset plate which could be used for
this purpose. It required formulating the fountain solution with
ferricyanide. We built a small building attached to the wall of the
stencil coaters at the Alexander-Ashburton corner to install the
coater.
